best way to take an image of the supernova with Rebel??
I just picked up a Canon Rebel T3 today. Although I'm primarily going to
use the camera for family outings and such, I may do a bit of astrophotography. I'd be brand new at this, although I used to image planets in the past with a C-8 and webcam (all sold now). So.... all I have right now is the camera and the lens that comes with it (55mm I think). I do have an ETX-90RA scope, but it hasn't been used in several years. I was hoping to maybe grab a few shots or even a single shot of the supernova in M95. It this possible with just the camera, could I use the ETX and camera, or ?? Since I don't have much of a clock drive, I realize I'd have to make exposures short and probably stack them. I want to try and catch this SN before it's gone. Thanks in advance for any help/ suggestions. Ron |

So you'll need the telescope. Imaging will be a challenge with this ETX, but you might pull it off. You will need an adapter to attach the camera- something like a T-to-1.25 tube. The scope will have to be well polar aligned, because you don't want images shorter than about 30 seconds. Even a single 30-second exposure will show the galaxy and supernova; the more you can stack, the better the final appearance. |
