So, Skywriter how would one go about looking through the finderscope on such a large Dobsonian telescope? :D The eyepiece looks to be about 10 feet off the ground! You must need stilts or a step ladder to operate it.

This is 2011. They sell video cameras and cables and Silicon Graphics O2's.

for +15 Grand you can afford a ladder ;-) actually they are working on ones shorter focal length but still large aperture.

@hamei: to me, the idea of spending a so much money on light gathering, only to substitute a technology with such poor low light performance in place of my eye doesn't make any sense. people have put webcam's on them but it's just not right... astrophotography is though as well since they lack an equatorial mount for low-noise tracking on long exposures.

besides there are shorter ones that are more affordable, and portable which is something that's very important is you don't live on a low light pollution tract of land. This is my most likely Dobsonian purchase http://www.obsessiontelescopes.com/telescopes/22UC/index.php

Back in 2001 I purchased my first telescope. It was a simple low cost Bushnell 4" telescope without any GOTO features or electronics. I remember the first time I looked through the telescope I was amazed at how bright the night sky was. If I pointed the telescope at the full moon without the aperture reducer it would daze my eyes from the incredible brightness.

At the time I had a Sony Mavica floppy disk based digital camera. This picture of Saturn was taken using the Bushnell telescope with eye piece projection and the Mavica.

With a 22" telescope I can only imagine what the night sky would look like.
