    I've heard AP is one of those "slippery slopes" in astronomy. We only have one serious AP guy in our group but several others have nice photography equip so they hack around and occasionally come up with very surprising results. I'm slipping a little too. It does give you an excuse to buy more gadgets though. Have fun, WEK.

    The appeal of AP for me, even casual AP, is that a short, 15 or 30 sec. exposure with a DSLR, will pull out some details clearly that you would barely (or never) see with your eye, even in a 16" monster scope.

    Keith, I suspected that the focus was probably a major cause. But its impossible to see just on the little screen of the camera that its perfect. I have heard "Bahtinov mask" being thrown around here on Astronomy Forum.

    I was going to look it up, but as I say, I'm NOT going down the AP route.

    Very good point David. I hadn't thought of it like that.

    Also, I really like your phrase "Casual AP". It kind of fits!

    Your photo is much more realistic than mine. Your stars look like stars, mine look like targets! Well done nice pic.

    That is true David. I have some pics with my camera on a fixed tripod and have noticed that I had caught, in my light polluted spot, the fuzzy blob known as Andromeda without trying for it.

    You have a longer exposure on yours and your image seems to have more content than mine.
