Hi,

OK, so this is rather an ignoramus question, but would I be able to capture the Rosette Nebula with an unmodded Canon DSLR on a 900mm focal length scope with an expo length of say, 1:00-1:30?

On a serious note, (not wanting my humour to get me banned)!

What would you suggest as the best method for taking white frames? I've been having trouble with vignette, but as my sensor is large, its more one-sided. (I'm ok with dust as my DSLR auto cleans the sensor every time it turns on or off).

Hi,

Nice pic, mate! Perhaps some photoshop to bring out the details?

I don't know whether this counts...?

Taken with a point and shoot cam, held up to the eyepiece of an Explorer 130 'scope. Expo of about 3 secs, undriven.

I'm hoping to get some proper DSOs with a DSLR I'm asking for at Christmas. If I had used the RA drive that I got a few months later, I bet it would have looked great, but, of course, the cam broke before then!!!
