    Joe,

    I know you are right about the 102mm. Fast F/5.0 scope, costing not a lot of money, I can't expect perfection.

    However, I will say that when used as an optical scope only, its worth every penny I paid for it. Open clusters for example are a real joy with low power eyepieces.

    It has taken my little foray into AP to highlight the CA problem.During visual I hardly notice it.

    Your other points are noted. Thanks as always for your help.

    Alec.

    Nice to see your first attempt Alec. I noticed you have an M70 award, does that mean you imaged 70 messier objects already? That was fast !

    I really enjoyed this thread. It reminded me my first adventure about 15 years ago when I attached my 35mm camera to a C8. My first pictures... They were so bad that I lost interest. In those days I didn't even know about processing. Within a year I sold all my stuff. What a mistake...

    When I moved to darker skies about seven years ago I started dreaming of AP again. So I purchased used equipment about 16 months ago. Fell in love with the hobby in not time at all, especially because of the goto technology and free processing software. I think you're hooked already...

    Like you, I'm stuck with an Alt Az mount, so I do short exposures only. I have the benefit of a good CCD camera though. I have an image of M45 with the exact same scope you have. It's actually quite a good little (and fast) scope. I recently upgraded to a triplet but I was quite happy with many of the images I took with my SW. You'll need to learn to process the CA out a little but that's not too hard to do.

    Keep it up Alec. It's such a wonderful hobby, and the people here quickly become your virtual family.

    Paul, no it doesn't. My M70 is the visual award only.

    One that subject, my Messier count has been stuck on 108 for ages now. I can bag M79 as its in Lepus. I will be left with only M83 to find but after studying Stellarium I must wait until April before it makes a brief appearance above the horizon.

    Very nice shot there Alec! I really like the color you got from it. Isn't AP fun after all?

    Now look here guys, I repeat I'm not going to do AP!!!!

    Anyway, last night at the observatory I did show a colleague a picture that I took a week or so back of M31.
    What this guy doesn't know about AP can't be worth knowing. Within minutes he put my feeble attempt into Photoshop and slid some sliders, bent some graphs and clicked some buttons. This software is so complex you must have to lock yourself in a darkened room for months on end to learn it.

    Anyway, it came out like this.....



    He told me that I had done the hard bit by gathering decent data (and freezing to death in the process!) I MIGHT try another target, but I aint apromising.
