Quick question: When I was in college years ago, we attempted astro-photography with a telescope you had to manually adjust, even though it had "tracking". Are things different now? I assume a lot of it is automated. Henry, Our mount tracks pretty well. We have gotten up to 2 min exposures w/ minimal trailing. We have not graduated to guiding yet, as our skys have too much sky-glow to make it feasable, but mostly because we are early in our learning curve. You are right, guiding can be automated for a surprising small cost. The software, PHD, is free & requires an inexpensive camera & spotting scope. The whole picture taking process can be automated, if fact, but I'm not sure we want to go in that direction. Rich

rich, you can build a 16" for less than the cost of a commercial 8"!! You can build it shorta short for the Messier imaging or kinda long for planetary stuff. Here is a link to one super nice one.jamesp, you can have your old mirror re-silvered for almost nothing. Hell even that is DIY!! Neat video, but I'm not sure I want to play with those chems. You guys are really tempting me though. Rich

you can send a self made mirror out for pro silvering.

Wow nice pictures. I have tried a few pics myself but got lost in the whole stacking process. I have one of the Orion nebula that I like. It's not highly detailed but I can tell what it is. Haven't used my telescope in a while...maybe I should drag it out.
