Richard; I use the equipment of the RAS Observatory in Cloudcroft NM. I do rent time on the scopes which allows me to use a variety of scopes and several different cameras at an affordable price and at a location with excellent observing/imaging conditions. The observatory has been receiving a fair amount of attention over the past year for the asteroid finding that has been going on there by international researcher from the US, Canada, and Europe. (It is one of the top sites in the world for discovering asteroids and for binary star research, all of which is done remotely as I do my imaging.) As for exposure times and processing details, I would be happy to share them for any specific image and hopefully I will find time in the future to include the information as part of the image caption. In general, I start with L=30x120sec. binned 1x1 and RGB=4x300sec each binned 2x2 for galaxies and Nebula. I use RGB=15x120sec binned 1x1 for globular and open clusters, and anything that seems to work for planetary nebula. Of course, I might modify the times and number of exposures depending on the specific object, blooming, seeing, etc., but the above exposure times are a starting point. For Narrow band images, I will use about the same exposure time but double the number of exposures for each image. This is primarily because I don't use guiding when imaging with the narrow band filters. I use MaxIm DL to calibrate and color combine the image and then curves, levels, etc. in PhotoShop CS for the final processing. I apologize for being a bit brief but until I find the time to include the imaging information as part of each image's caption, I hope this will do for a general answer. I would be happy to give specific information for a specific image(s). Thanks for your interest and please let me know for what images would would like specific information.

Ed,
Some lovely images. It would be nice if you included exposure times and processing details (if you don't mind).
How did you get access to this scope? Is it a pay-per-use instrument, or...?

Hi Everyone; This is my first post to the group and although it doesn't deal with the Science/Religion discussion, it does deal with Astronomy. With the help of Cynthia Blue, I was able to set up a photo album with a number of images that I have imaged over the past year. These images can be viewed at: utahastronomy.com My album is the fifth album on page three under the title of Ed's Album. I hope you enjoy them and, as always, any comments or questions are welcome. I have recently tried my hand at narrow band imaging of Nebula which has turned out quite well. The narrow band images are of M8, M16, and M17. Most of the others are LRGB images. Enjoy; Ed Lunt
