Quote:Abell12 1/30/2008 00:15UT; Pickering 9, NELM 6, SQM 20.816" SCTUnfiltered at 260x the PN is lost in the star's glare. However, if you move the star around the in a circle just outside the field-stop, an egg-shaped section of the glare remains when the star is off the ESE edge. PN easy in averted, and sometimes direct vision with aggressive filtration (OIII). No structure in PN, but it does have somewhat of an egg shape.

Quote:As a quicky, rough example, here's sort of what I meant. I'm not very good at this at all.
Quote:I see the spiky version at a much smaller scale, surrounded by the halo.
Quote:Jeff,You need to ask "yourself" some questions at some point- which way "do I think is best"? Am I trying to make a pleasing sketch for myself or others? Am I trying to make a realistic sketch as I see it? Am I trying to do all of these at the same time? If the seeing is very good you may see diffraction rings in addition to spider diffraction spikes. Should I put all this in a sketch? If the seeing is bad the stars may be blurred. Should you sketch the stars blurred if they look that way? Should you sketch them the way they look under ideal conditions if conditions are not ideal?These are the kinds of questions you are asking yourself now. Jeff, your sketches are fantastic and continue to get better. Certainly better than anything I have done. I don't feel there is any one best way. I have yet to make a sketch I am completely happy with. It may never happen. But the quest is the fun part anyway.The variations in sketches submitted here makes this a wonderful place to visit, look and learn.For me there is no one best way to sketch anything astronomical. All sketches are the mind-eye-hand of our fellow beings. Vive la difference!Frank
