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 __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
Holy cow! What were you using with the Horsehead photo -- camera, telescope, etc.? These are beautiful. Thank you for sharing them. -- Joe
Hi Joe; The camera I used is a Takahashi Mewlon locate at the RAS Observatory in Cloudcroft New Mexico. The Camera is a FLI-IMG 1024 Dream Machine. The image is a RRGB. I used 12x300sec for the R unbinned, and 4x300sec for each of the RGB binned 2x2. Total time: 2:00hrs. The wide field was with a Sky 90 camera also located at the RAS Observatory. Thanks for looking; Ed L --- Joe Bauman <bau@desnews.com> wrote:

Ed, really a nice set of images applying the "NASA" three color technique using SII, OIII and Ha filters. (Wasn't that discussed in last month's S&T.) It really brings out the structure of the gas clouds. What are you using for the night Ha filter? Where do you buy an SII filter? How much? I though they were running around $80 in ads in S&T. - Canopus56(Kurt) __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Hi Kirt; Glad you liked the images. The images were taken remotely through a telescope (a Takahashi Mewlon) and camera (a FLI-IMG 1024, Dream Machine) located at the RAS Observatory in Cloudcroft, New Mexico. (Co-located at New Mexico Skies). As for narrow band filters, two good sources are: AstroDon filters: www.astrodon.com and Custom Scientific, Inc.: www.customscientific.com/astrostand.html The specific filter for this particular Horsehead image (the close up)was not an Ha filter. The image is a RRGB image where I used the R filter for both the L channel and for the R channel. The Ha filter I use for the Narrow band is usually the AstroDon. Yes, the NASA technique was discussed a month ago in S&T. I actually like the images better using their technique of having the SII image in the Red channel and the Ha image in the Green Channel, better than the traditional order of Ha for Red and SII for Green.

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...? -Rich --- Edward Lunt <lunco@yahoo.com> wrote:

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.
