Hello everyone, despite my login name you can call me Pete. I am a 68 year old great grandfather who has been dabbling with astronomy who now see's away to get the gr-grand kids introduced to the Universe in a manner they might even slow down enough to see. That and lugging around the 10 in Dob has lost my enthusiasm! I had been researching the move to Goto and Gem but was being challenged by the size of an APO to accommodate my experience of the DOB. This looks more doable. So I will be using this site to get up to speed and will appreciate recommendations. Good viewing to everyone. 1st question How do I view the Beginners Videos? They are marked private. Thanks

Welcome to the forum, Pete!
The great thing about Video Astronomy is that the sensitivity of cameras can effectively multiply your aperture by a factor of 3. So a 80mm APO (I got mine used for $500US) acts like its a 240mm (almost 10"). And if I do a little live stacking, I can increase it from there. I usually don't need to do so. I had an 80mm APO on an AVX Mount with a video camera blowing away a 6" refractor with a $250 eyepiece - getting colors in my objects where the visitors were seeing it in B&W thru his visual setup.

G'day Pete, welcome mate. Fantastic that you want to pass along your experience and knowledge and share it with your grandies  As for the Beginner Videos, if you mean these ones of mine: astrovideoforum.proboards.com/thread/1198/introduction-video-astronomy-tutorialsI have blocked them from public view because after posting them on 'You Tube' I realised they are more like 6 x 5 minute long advertisements for one particular Camera Vendor. I intend to make a new series with no particular brand bias. Sorry about that if they are the ones you mean. |

Hello Pete
Wecome to the group.
I'm pretty new here and my astronomy background (and age) is very similar to yours.
Video astronomy is great. Dim eyes and sore back don't matter and as Rick says you can get amazing views from a small scope and inexpensive CCD/CMOS camera.
