VENUS TRANSITS THE SUN
*VIEWING THE SUN WITHOUT THE PROPER FILTER MAY CAUSE PERMANANT BLINDNESS* 
On June 8th Venus will pass in front of the Sun. The event is very rare having last occured in 1882. The event can be 
seen using a telescope or binoculars with a suitable filter, solar projection or eclipse glasses. Using eclipse glasses, 
the image of Venus will be very small and may be difficult for some viewers depending on location and maybe age.

New Zealanders will unfortuneatly miss the event since the transition will start at sunset. As we move west, the event 
will start earlier in the day when the Sun is higher and easier to observe. Observers in Sydney will witness the start 
around 3.00pm. For observers in the middle of Australia (Adelaide), Venus will start its transition around 2.30pm. 
The entire event will be widely visible from the Europe, Africa and Asia. The transition will last for about 6 hours.

When Captain Cook made his original voyage south in 1769, it was to observe the transit of Venus from Tahiti. 
The scientific importance of the transit was to use it to measure distances in the solar system. Captain Cook 
was specifically chosen because he was amougst the very few who knew how to work out longitude. Together 
with his seamanship, he was a particularly special person, and only he could have made the voyage. During 
the voyage, he opened his secondary secret orders which reveiled he was to discover the great southern 
land (Australia) and claim it for Britain.

More information on the event will be on our web site which is currently being put together.

Eclipse Glasses $8AUD$. 
Telescopes and binocular Solar Film $45AUD$ per square foot. (any size available) 
Celestron telescope Solar Filters are available in all sizes.

For Solar Projection, eyepieces which are multi-elemented and use glue in their construction, will be 
damaged. It is best to use 2 element eyepieces (Huygen) or similar, and reduce some of the light 
entering the telescope. Reducing the light entering the telescope can be acheived by attaching a 
peice of cardboard over the end of the telescope which has a small hole cut out of it. This will make 
little difference to the image, and in some cases, improve the image.

31.8mm (1.25") Huygen Eyepieces $30


CURRENT COMET 
C/2001 Q4 NEAT - best seen between March 10th and 24th.

Comet NEAT is increasing in brightness, and according to current calculations, will be visable to 
the naked eye. The comet is postioned well for southern hemisphere observers and is visable now, 
although the brightness of the Moon will make things difficult. Once the Moon disappears, the comet 
will be easily observed through binoculars or telescope.

Here is a site which will make finding the comet easy:

FILTER SPECTRUMS by Terry Moon
Terry Moon (yes that's his real name) has completed some wonderful work on measuring the spectral 
transmissions of popular Wratten, Minus Violet and IR Filters. This information he has made available 
to everyone. The analysis will appear on our web site soon. However, anyone wanting the information 
now, can let me know, and I can send it in an email attachment.


ACCURATE FOCUSING OF TELESCOPE CAMERAS
The latest meeting of our local astronomical society (Astronomical Society of South Australia) had 
the usual array of guest speakers including Perry Vlahos (president of the Astro Society of Victoria) 
who spoke about the wonderful acheivements of William Hershel, Phil Rodgers who spoke on the 
use of binoculars for astronomy, and Blair Lade. Blair brought along his SkyWatcher Heavy Duty 
EQ5 Mount and 80mm refractor which had the Philips ToUcam attached. Using the setup, focused 
on black material with some white dots to represent the stars of the Southern Cross, blair showed 
us a way of accurately focusing the camera. He simply put a piece of paper over the end of the 
telescope which had 2 holes cut out of it. The star's images, represented by 2 holes each, were 
clearly seen by all on the projector screen through his computer. Blair then proceeded to focus 
the image by simply adjusting the focus until the 2 holes became one. This was greeted with a 
round of applause.


RARE JUPITER MOON TRANSITS
On March 28th, 3 of Jupiter's moons will transit (travel across) the face of Jupiter together. The event 
will be difficult to see due to the event occuring around sunset. The other problem is Jupiter will be 
quite low in the sky causing us to look through a fair amount of earth atmosphere. However the 3 
moon transit will not be seen again for another 41 years! As with all the moon transits of Jupiter, 
the shadows of the moons are the only feature which can be seen. The moons themselves cannot 
be seen as they are camouflaged too well by the planet.

Observers in the eastern states of Australia (EST) will see the event starting around 6pm. At this 
time it will be very difficult to observe. Observers in locations moving west will have even more 
difficulty in observing the event, since in Western Australia, the event will begin at 4pm. Obervers 
in other parts of the world will need to check for suitable observation times. There doesn't seem to 
be much information on the internet for the event.

The first true measurement of light-speed came in 1676 by Olaf Roemer. He observed that the 
time elapsed between eclipses of Jupiter, with its moons, became shorter as the Earth moved 
closer to Jupiter, and became longer as the Earth and Jupiter moved farther apart.


CELESTRON'S NEW LOWER PRICES
Celestron have announced new lower prices to improve competition. Anyone needing a quote on 
Celestron equipment or accessories can send us an email.


BULK MIRROR PURCHASE
We are once again organising a bulk purchase of product from Newport Glass in the US. Orders 
need to be in by the end of June. The bulk order enables purchasers to save money as we order 
the items in one large shipment. Newport Glass are specialists in telescope glass making materials 
including mirrors, blanks and tools. Blanks include pre-generated curves and Schmidt-Cassegrain. 
The products Newport Glass produce can be seen at their web site:

http://www.newportglass.com/


EXCELLENT SHORT FOCAL LENGTH REFRACTOR
Have you been searching for the ideal short focal length refractor? The Orion 80mm F/7.5 ED 
Apochromatic Refractor Optical Tube Assembly is $850AUD. The assembly includes a 2" 
Focuser with a 1.25" adaptor.

Company 7 do a number of optical tests on the refractor after they arrive from Orion to ensure 
the highest quality. A review of the refractor can be seen here:

http://www.company7.com/orion/telescopes/orion80EDf7.5.html


SKYMAP PRO SOFTWARE V10
The new SkyMap Pro V10 is now available. Full version is $190AUD$ or $129US$. Update 
Version is $98AUD$ or $68US$.

All information concerning SkyMap Pro can be seen here:

http://www.ttp.co.uk/abtskypro.htm

A free trial download is available.


UPDATED VIXEN PLANETARIUM PAGE
Although Vixen products are very good, everyone agrees they have a definite lack of information 
available. Maybe its because of the many Chinese copies of their products.

One of Vixen's products for which there is little information is the 800M Home Planetarium. 
We have used the 800M and found it to be a very good quality made product and useful for 
teaching purposes. The 800M isn't available in the US, although, we have them available for 
US buyers. Information on the 800M has been further updated on our web site:

http://www.telescopes-astronomy.com.au/vixen113.htm

Please call or email for pricing.

VARIOUS

ASTROSYSTEMS LIGHT PIPE/SIGHT TUBE & AUTOCOLLIMATOR
AstroSystems are well reknown for making quality telescopes and accessories. When it 
comes to collimating your telescope (alignment of the mirrors) accuracy is important especially 
if the focal ratio is short. The Light Pipe and Sight Tube is used in combination with the 
Auto-collimator to get an exact alignment. For those who already have an alignment tool, 
Chesire Tool or Laser Collimator, these tools only do half the job. The AutoCollimator is 
used to ensure exact alignment. More information can be read on AstroSystems site:

http://www.astrosystems.biz/coltlsm1.htm

Light Pipe/Site Tube Combination $99AUD$ 
AutoCollimator $95AUD$

If both are purchased there is a discount of $12AUD$ ($182AUD$)

GREEN LASER POINTERS
5mw Green Laser Pointers are $150. The lasers have a horizontal range of around 2km. 
Higher milliwatt lasers are available, although 5mw are ideal for astronomical purposes of 
pointing out objects. Green Lasers are dangerous if pointed into the eyes and need a degree 
of care when used.

URANOMETRIA 2000.0 DEEP SKY ATLAS (NORTHERN HEMISPHERE)
Error in your favour! We were sent the wrong edition of Uranometria, so its going out on 
special for $70AUD$ or $48US$. A description of the world famous atlas can be seen here:

OPPOSITION OF SATURN
On December 31st, Saturn will be at its closest and brightest for the year (opposition). 
What makes it special this year is the Rings of Saturns reached their full tilt (as far as 
they go over period of 15 years) towards us only a few months ago. This will allow 
observers to see the rings in good detail.

FILTERS FOR SATURN
Here's some filters which are useful for Saturn Rings: 
Wratten #11 - Yellow/Green 
Wratten #47 - Violet 
Wratten #21 - Orange

2X BARLOW / CAMERA ADAPTOR / FILTER HOLDER - SPECIAL!
$70AUD$ or $44US$ 
In stock are these marvelous 1.25" diameter adaptors. They are able to do a number of 
things. Firstly, its a achromatic 2x Barlow. Secondly, its a camera adaptor, which 
is threaded, and only the T Mount is needed to suit your brand of camera. Photos can 
then be taken through a telescope at higher magnification without using an eyepiece. 
Thirdly, the Barlow's lens can be removed by unscrewing for true focal projection 
photography. Fourthly, with the Barlow's lens removed, filters can be screwed in. - Crikey!

WHAT FILTERS ARE YOU USING?
Terry Moon of the South Australian Astronomical Society has completed testing various 
filters with some interesting results. Is your #23 Filter really a #23 or is it closer 
to somethng else? The outcome of his extensive tests will produce the correct filter 
for the application for which is was purchased for. If you are interested in the 
results, let me know, and once testing is finished, we can forward a summary of the 
conclusions. We will also place the results on our web site.

One of the results obtained is the Wratten #56 appears to match the Johnson V-band 
and can be used with CCDs for accurately measuring stellar magnitudess the Wratten 
#56 filters.

EYEPIECE DEAL - SPECIAL!
The Telescopes and Astronomy Eyepiece Deal was first initiated in February when 
the last of Celestron Eyepiece Deals had been sold and no more were on the horizon. 
Many people were left wanting similar deals. The major difference between our Deal 
and Celestron's Deal is you don't have to buy a telescope to receive the Deal.

We have now updated the eyepieces. The Deal no longer contains the eyepiece filters. 
We have reduced the price.

The Deal consists of 6 eyepieces. There are a number to choose from since most 
people already have a mixture of 10mm, 15mm or 25mm which are standard with most 
telescopes nowdays.

6 Eyepieces - Plossls. The rubber eyecup can be removed to attach a digital camera. 
$180AUD$ or $114US$ plus postage.

There are a number of eyepiece focal lengths to pick from: 
4mm 
6.5mm 
10mm 
12.5mm 
15mm 
20mm 
25mm 
30mm 
40mm

To work out the magnification of an eyepiece:

Divide the telescope focal length by the eyepiece focal length.

BINOCULARS - SPECIAL! 
25x100mm Binoculars $650AUD$ or $340US$ or £264

TELESCOPE CONSTRUCTION WEBSITE 
Building your own telescope from our supplied parts has many advantages: 

1) Allows the builder to choose standard or high performance parts. 
2) The telescope can be made to a particular budget. 
3) Allows the builder to make the parts he or she wants to and buy the rest. 
4) The eyepieces can be choosen to suit the telescope and user. 
5) Allows the builder to design the telescope according to the proper specifications. 
6) Allows the builder to choose a mount which is properly suited to the application. 
7) Depending on parts used, there is a cost saving. 

Telescopes and Astronomy's Telescope Construction web site hasn't been updated 
properly since Mars had taken over our lives. We will hope to complete the site 
within the next 2 weeks or by the time this Newsletter arrives. The site already 
contains much information and pricing:

It is intended for anyone who has looked up and wondered, whether it be with 
the unaided eye, binoculars or a telescope. It is intended to give a tourist's 
view of the sky as a 'use anytime' reference with realistic views identifying 
the positions of each object. It is also the easiest reference to use to find 
a planet's position in the night sky. The 2004 Edition contains 8 extra pages 
including the 2 expected bright comets, and the rare transit of Venus, both in May. 

For more information see it on our web page: 

http://www.telescopes-astronomy.com.au/telescopes062.htm

DECENT MOUNTS FOR ACCURATE TRACKING (FROM LAST NEWSLETTER) 
We've had a huge reponse to this article posted in the last Newsletter, so 
we've repeated it for those who are new or missed it. 

Having a decent mount for accurate tracking is becoming more popular as 
they become more affordable. Accurate mounts are used for a number of 
things including computer guided telescopes, accurate encoder locating 
(see below) and astrophotography. Of course, you only get what you pay for, 
although with right know how, many mounts can be improved to greatly increase 
their accuracy. Once these mounts are improved the Vixen SkySensor 2000 PC 
can be attached. 

VIXEN GP-DX
$1420AUD$ or $824US$ 
One of the best mounts available is the Vixen GP-DX. The mount comes as the 
'mount head only' with a tripod or pier needed to complete it. Included with 
the mount head is slow motion controls, polar alignment scope, bubble level 
and built in illuminator. The GP-DX can have a dual axis drive added. The 
mount can handle upto 10kg easily. Vixen SkySensor can be attached to the 
GP-DX (see below). 

SKYWATCHER EQ5
$499AUD$ or $313US$ - SPECIAL! 
There are a few copies of the Vixen GP-DX mounts available. The EQ5 comes 
complete with tripod. It can have single or double axis motor drive attached. 
Standard features of the EQ5 include a built-in holder for polar scope, a 
latitude adjuster with micrometer scale, an azimuth polar-alignment adjuster, 
slow-motion tracking controls, and a bubble level. The EQ5 can be greatly 
improved and the best way to do this is to follow the guidelines set out by 
AstroBoy at his site: 

http://www.astronomyboy.com/

Once the EQ5 has been improved, the Vixen SkySensor 2000 PC (see below) 
will work accurately and can be attached without difficulty (bolts straight on). 

SKYWATCHER HDEQ5MNT
$1099AUD$ or $656US$ 
This is the heavy-duty version of the EQ5 mount and is a smaller version of 
the sturdy EQ6 mount. It is able to handle around 12kg. (up to 10" reflector) 
The HDEQ5MNT includes dual axis drive, built-in polarscope for both North 
and Southern Hemisphere use, large R.A. and DEC. locking clamps and 
retractable counterweight shaft and counterweight. The tripod has 1.5"-diameter 
steel legs. 

Once again, when the HDEQ5MNT has been improved, the Vixen SkySensor 2000 PC 
(see below) will work accurately and can be attached without difficulty 
(bolts straight on). 

SKYWATCHER EQ6
$1485AUD$ or $936US$ 
This is the largest and heaviest mount. This mount can handle a 12.5" 
Reflector or similar (up to 18kg). Features include built-in polarscope 
for both North and Southern Hemisphere use, large R.A. and DEC. locking 
clamps, dual axis drive, and retractable counterweight shaft and counterweight. 
The field tripod has adjustable height, incorporating 2"-diameter steel tripod legs. 

Same again, once the EQ6 has been improved, the Vixen SkySensor 2000 PC 
(see below) will work accurately and can be attached without difficulty 
(bolts straight on). Further information about the SkySensor and the EQ6 
can be seen on this site: 

http://www.iteastronomy.com//products/accessories/overview.php?p=EQ-6+MOUNT


CELESTRON CG5 
$1042AUD$ or $616US$ 
The Celestron CG5 is basically the same as the EQ5. The CG5 has the Polar 
Alignment tool as an optional extra. AstroBoy gives the CG5 a full going 
over on his site: 

http://www.astronomyboy.com/

Same again, once the CG5 has been improved, the Vixen SkySensor 2000 PC 
(see below) will work accurately and can be attached without difficulty 
(bolts straight on). 

Call or email for further information. 

CELESTRON CG5 COMPUTERISED MOUNT
$1599AUD$ or $962US$ 
This is the same mount as the CG5 with computerised GOTO and object database. 
Celestron has all the specifications on the following page: 

http://www.celestron.com/prod_pgs/tel/c8sgt.htm

CELESTRON CGE COMPUTERISED MOUNT
$7640AUD$ or $4500US$ 
This is Celestron's top of the line mount. I haven't seen one personally yet, 
although, going by the reviews it is a very good mount indeed. The largest 
telescope Celestron place on it is the 14" Schmidt-Cassegrain which weighs 
20kg (45 pounds). This doesn't include any extra accessories which could be 
an extra 2kg. The best way to see the specifications is to go straight to 
Celestron's web page: 

http://www.celestron.com/prod_pgs/tel/cge_index.htm 

Any additional information can be obtained from us. 


VIXEN'S NEW SPHINX MOUNTS AND STAR BOOK
Vixen now has available its new SX and SXW Mounts. These mounts have been 
engineered with the latest innovations like using the motor drives as the 
counter balance instead of weights. Most of the telescopes Vixen produce 
are available on the new mounts. 

The new Vixen Star Book is a GoTo Controller with a planetarium screen for 
locating objects. 
Information on the new Sphinx Mounts and Star Book can be seen on the 
following pages:

ENCODERS FOR TELESCOPES (FROM LAST NEWSLETTER)
$540AUD$ or $328US$ 
Complete Encoders Kits available for Dobsonian and Equatorial Mounts. 
The Encoder Kits include the following: 

- 8192 step encoders 
- modular connector 
- enough cable for big Dobs

MAX or Celestron's Advanced Astro Master. 

JMI's NGC MAX 

http://jimsmobile.com/guide_search.htm

Celestron's Advanced Astro Master 

http://www.celestron.com/access/comp.htm

The Discovery Display includes R.A./Dec. display, timer, polar alignment 
help, Identify mode, RS-232 computer interface and a 12,046 object database. 

The Discovery Display database includes all 110 Messier objects in the 
Messier catalog and all NGC objects in an NGC catalog. The IC catalog 
consists of all IC objects which are not galaxies, galaxies which have a 
magnitude specified and all remaining galaxies which have a size of 1.9 
arc-minutes or more. There are separate catalogs for 928 stars and 386 
other non-stellar objects, including 19 black hole candidates and quasars. 
An additional user catalog includes 28 user-defined objects. A planet 
catalog is also included. 


2X BARLOW / CAMERA ADAPTOR / FILTER HOLDER - SPECIAL!
$70AUD$ or $44US$ 
In stock are these marvelous 1.25" diameter adaptors. They are able to 
do a number of things. Firstly, its a achromatic 2x Barlow. Secondly, 
its a camera adaptor, which is threaded, and only the T Mount is needed 
to suit your brand of camera. Photos can then be taken through a telescope 
at higher magnification without using an eyepiece. Thirdly, the Barlow's 
lens can be removed by unscrewing for true focal projection photography. 
Fourthly, with the Barlow's lens removed, filters can be screwed in. - Crikey! 


EXTRA COUNTER WEIGHTS
We have additional shaft weights available in 1.9kg. The weights are 40mm 
thick and 90mm wide (same as Vixen weights). 
$40AUD$ or $25US$ each. 


GREEN LASER POINTERS
Green Laser Pointers are available in differrent powers up to 28mw. 
Standard Green Laser Pointers (<5mw output) are $160AUD$ or $99US$. 


WHAT FILTERS ARE YOU USING?
Terry Moon of the South Australian Astronomical Society has been testing 
various filters with some interesting results. Is your #23 really a #23 
or is it closer to somethng else? The outcome of his extensive tests will 
produce the correct filter for the application for which is was purchased 
for. If you are interested in the results, let me know, and once testing 
is finished, we can forward a summary of the conclusions. 

One of the results obtained is the Wratten #56 appears to match the Johnson 
V-band and can be used with CCDs for accurately measuring stellar magnitudess 
the Wratten #56 filters. 


SURVEYOR TRIPODS
We've found the biggest, sturdiest Surveyor Tripods available. The smaller 
of the two handles up to 20kg and is priced at $250. Secondly, the larger 
one handles up to 40kg for $480. These tripods can be easily adapted to 
Mount Heads like the GP-DX for far less than other expensive tripods. 
Please call or email for further information.
