What lenses should I get? I want to get similar photos!!!!
A Questar 3.5" telescope with 2 Dakin 2X Barlow lenses like I use will do nicely. I would expect that any high quality 90-100 mm long focal length Apo refractor could do as well, but would be less convenient than the Questar. Gathering the data is just the first step and the processing afterwards is just as important. I have a tutorial article on my day-lapse technique at: astronomy.robpettengill.org/daylapse.html
