So here's the question. I can't afford both right now, or in the near future, so which have you found gave you the most enjoyment. I realize they are two different animals. One satisfying one's enjoyment at the eyepiece and the other a delayed, more technical pleasure. I like both ends and think I'd be happy going either way; but would like to hear some other observations/opinions.

Don't even know what these things are called, so the searches haven't worked.

Thanks in advance.

Hi folks,
I have an f6 newtonian on autostar driven GP mount.
I have a SOnt A-100 and Nikon D-80 DSLR. What do I need to get started, and I guess everyone prefers using the Nikon rather than Minolta? Do you think I need 2" T-Adaptor or is 1.25 sufficient? Obviously if I have to get 2" barlow it will be $$$.
Any quick suggestions, and what do you use for image processing from DSLR? Do you take a good few shots and stack them like on webcam?

Any advice much appreciated.
Martin

I bought one from scopestuff (here http://www.scopestuff.com/ss_adt2.htm), but....

I want to use this on my AT66ED which is a problem. This adapter assumes you are screwing it into the back of an SCT so the butt end of the adapter hits the back of the SCT and stops. With the AT66ED, it just keeps going and there is no way to tighten the adapter. I need one with and internal stop.

Anyone know of such a beast? Yes, I know I can have one custom made....

TIA,

roland

Just want to know how you do a precise polar alignment with the Titan.
Do you guys use a torpedo level to level the top of the mount when the weights shaft is down pointing streight down ?
I just want to have an exact polar alignment before I start getting into the PEC or so. My mount is on a portable pier and I will use it for astrophotography and want an exact aligment as possible.
Just want to know how you guys are doing this.
Is there a avi or picures aviable how to do it right ?

I have a few questions for the group on DSLRs. First, is there a way to process out amp glow from a D70 when pushing it to higher ISOs? I am sure there probably is (dark field sub?) but not sure how this is done if you have a DSLR. I am familiar with doing it in AIP for ccd fits files or with automated functions of SBIGs software, but haven't a clue for dslr JPEG images.

Second, What is the latest best choices on a budget? I would get a body only for astro use. I have a D70 that seems to work great for daylight. XTi? 40D? Is a 20Da the premier camera or one of the newer standard cams with live view?

Third and last, whats the best XT/XTi mod for astro only through a APO?

clear skies,
Kevin

Hi all, I recently bought a used Celestar C8. It was not abused but perhaps a bit neglected. I see some smudges etc on the front corrector. I've seen some methods for cleaning but wondering how risky it is. I don't want to make it worse. also, the focus knob seems to catch once per revolution in the same spot. Is this normal? Is it a common problem? is it something that me a novice can fix?

any help greatly appreciated. also any tips that will help me get the most out of it

Thanks in advance, Jerry Mead
