Hi, Shot M97 last night from remote scope in New Mexico: http://www.astroshow.com/Nebulae/M97.html Semi-pleased with the result. Slight elongation of stars in the Dec direction is making me moderately unhappy. Need to consider recalibrating guiding. Thanks to Mike Zele in China who suggested using binning for guiding! I was able to guide reliably on a star of Magnitude 10.45 at bin 2 which was impossible at bin 1. This is essentially the same as averaging 4 images so it improves the signal to noise ratio. The scope is operating at f/10, and the guider at bin 2 is operating at 1.1 Arc Second per pixel which is the limit of seeing on the best of nights. So the Dec guiding error was not because of the binning. At least that's what I think at the moment... Probably need to recalibrate guiding. Need a night of good seeing, no clouds, no wind... Hard to come by lately! Thanks, Howard http://www.astroshow.com -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
