In Reply to: the "what's the best . . ." question and how to conquer it posted by Hi-Fi Nut on May 13, 2012 at 01:40:29:
It is a question that ends with questions.
If you wish to photograph nebulas and other large, colorful things, you want a lower power astrograph. That might be a Achromatic lens design, a reflector or compound reflector. You will need something like an SLR camera or a larger format CCD camera made for this (which normally has a cooler for he CCD).
If you’re into planetary pictures, you need a higher power telescope in the 1500-3000mm focal length. The hot lash for this now is a small format CCD camera like the 618 from imaging source. Taking video allows you to save only the sharp focus frames and stack them into a high res picture.
If you’re mostly a visual observer, it is hard to beat an 8-12 inch Cassegrain telescope with a selection of eyepieces. A motorized mount will make life much easier a computer driven GOTO mount (once aligned) makes looking at a list of things a breeze.
Fwiw one of the most gorgeous objects in the sky (and reasonably bright too) the great nebula in Orion will be to the south starting in a few months (late fall / winter).
Hi fi is the same thing, you have to know enough to know what technical questions to ask and it depends what you want to do exactly what works best and even at that, it is partly a matter of fashion and fad.
Those answers are often not best answered by those selling the goods in question but slow methodical investigation.
