You're right Ryan and I'm not sure where I got the other two numbers from. I obviously didn't pay attention to the golden rules : Read the question carefully and always check your work before handing it in!
This would be a great target for your new scope. More focal length and bright enough to overcome your higher focal ratio. I took this at about 3.30am this morning from my suburban front yard, there were no clouds until about 4.45am when traces of high cloud appeared and thickened by 5.00am. I got to bed at 5.30am.
