Hey Loopy, just a bit of advice on the EQ2 and 3 mounts for photography.
*Dont do it*.
They are just not sturdy enough. I have a 102mm celestron refractor on a modified EQ2/3 (no one seems to be able to tell me exactly which one it is ) and if my neighbours f**t in bed the thing shakes. And thats after I've stripped it down, cleaned, smoothed rough gears and bearings, regreased and tightened as far as I dare (thats the mods as per
http://www.astronomyboy.com/cg5/index.html guide for EQ4/CG5 mounts).
Its ok for quick photos of the moon, as long as you have a prefire or mirror lock on your camera (or using digital) especially for exposures slower than 1/90 sec. Exposures longer than 1 sec I have to use the timer and set long exposures, 6 - 10 sec and use the black hat teqhniques to help reduce the shakes showing up in the image. I'd hate to see what these mounts are like with a 5" or 6" refactor on them.
Visually they hold the scope well, but expect quite a few seconds for the shaking to stop after every time you try to refocus, which is a challenge in itself. Part of the problem is the "tinny" aluminium legs and partly the internal mount engineering and construction, and partly they are just too small for even a modedrate refractor. Reflectors may be lighter but I think you would be disappointed
There are also RA drives available but the Periodic Error is terrible (the one I have any way). However to be fair the poor performance may simply be from the difficulty getting accurate polar alignment. I've gotten fairly good at visually polar alignment using this scope (forget about trying to get a polar scope for it, I tried for months and could only get Northern Hemisphere scopes that would fit), and once I have gotten a relatively good alignment I would slew to a star only 30 - 50 degrees away and slew (manually using the clutches, RA and DEc drives only have 2X an 8X guide rate unless you modify one) only to find I was then degrees away from polar alignment.
Having said all that if you do get one I guarantee that you will very quickly learn how to recognise a good mount and a poor one and how to work within the limitations of your mount.
Good luck with your choices
Paul
