Hi all,

I have to get a 10" mirror re-aluminized. Can anyone give me contact details/web addresses of any place that does this?

Thanks in advance.

Lens cleaner

Posted By Maurice Clark

Hi all.

I have to try and clean a 100+ year old 10" clark refractor. Since the lens is air-spaced I am reluctant to do it with detergent/propanol in case some of the liquid seeps between the lens elements.

I believe that there is a solution that can be sprayed onto a lens and then peeled off, taking dirt with it. Anyone know how good/safe this stuff is? Also, if it is suitable, where can it be obtained. I am in central Pennsylvania.

The lens is uncoated. (not counting dust, grime etc! :-()

Thanks in advance.

Stolen 30-inch Starmaster

Posted By Maurice Clark

Hi everyone,

This email just came over the amastro mailing list. Hopefully the @@##$$%%*&*&& will be caught and the scope returned to its owner! It must hurt!

Might also be worth keeping an eye out on all second-hand scope sites.

A StarMaster 30" telescope w/ an Argo Navis DSC and a White 17' Haulmark "V" nose, tandem wheel trailer which has a ramp rear door and a 36" side door on the right. Items were taken from my residence in Albuquerque, New Mexico in the early morning on Thursday, 13 November, 2003. Also included in the trailer was a Craftsman brand tool cabinet that contained hand tools of approximately $1500 value, and two 10 ft Tripod ladders (Louisville red fiberglass and Tallman aluminum).

Any information on the whereabouts of these items would be greatly appreciated. Please contact the Albuquerque Police Department.

Comet Encke

Posted By Maurice Clark

Hi all,

Some time back the question was asked about comet Encke's visibility. It is very well placed for viewing now and quite bright. (as far as comets go!) However it is very large and diffuse, so low magnification is best for viewing it.

Here is an image I managed to get last weekend before the clouds rolled in. It is processed to show the central condensation of the comet and approximates a high magnification view of the comet.

2 minute exposure, 8" f/6.3 LX200 and ST-9E

Cheers

Want a good laugh?

Posted By Maurice Clark

Hi everyone,

While searching for something on the web, I came across a page of astronomy humour. Some of it is very good! Here is one section entitled: "You know you're a Deep Sky person when...."

1. ... you consider the moon a major annoyance.
2. ... you consider Jupiter 'light pollution'.
3. ... you spend most of your time looking at or for objects you can barely see.
4. ... your favorite objects are objects you can barely see.
5. ... you enjoy looking at faint fuzzies with the smallest possible aperture.
6. ... you enjoy looking at faint fuzzies with the largest possible aperture.
7. ... you like to choose objects that are easier to imagine than to see.
8. ... your observing schedule demands that you search for objects in twighlight.
9. ... you keep thinking that if only the stars would go away, it might really get dark.
10. ... you wonder how your favorite objects missed getting included in the New General Catalog or the Index Catalog.
11. ... you're not sure that anything in this solar system counts as astronomy any more.
12. ... you're amazed that anyone needs artificial light to read charts.
13. ... you could do a Messier Marathon from memory, if you still bothered with Messier objects.
14. ... you can read all the NGC abbreviated visual descriptions without using the key, but you have to be careful not to cheat by just remembering what things look like.
15. ... you view a major earthquake as an opportunity for a close-in dark-sky star party.
16. ... you welcome (and have even considered instigating) power cuts, but only if they occur on clear moonless nights.

A few test images M33

Posted By Maurice Clark

Hi everyone,

Finally had some clear skies and managed to take a few test images with my C-14/TITAN/ST-9 combo. This one is M33 and is a combination of 2 10 minute images. The C-14 was used with a focal reducer to give a focal ratio of about f/7.

Dark subtracted and initial processing with CCDSoft and then touched up with Photoshop using curves and levels, and a light unsharp mask.

Enjoy
