Re: [Utah-astronomy] New Image - Veil Nebula Complex in Narrowband

Don, The ME is impressive. I ran PemPro to determine the raw periodic error: it came out as less than +/- 1 arcsecond. That is before applying PEC. Unbelievable! I don't know if PEC is even needed. On the last clear night I took several 10-minute unguided images and the stars in the middle of the frame are tiny round dots. I am also learning about "The Sky X" and its features. I especially like the automatic sky mapping routine. I can start it and sit back and watch. It selects random targets throughout the sky, slews to the target, takes a picture, precisely plate solves its position, and moves on. After the routine is complete, every object is dead center of the crosshairs. It is not a big deal with the Borg 45ED at 325mm, but it will be nice with the longer focal length. I love the mount!

New Image - Veil Nebula Complex in Narrowband
by Tyler Allred 25 Nov '12

25 Nov '12

Hi all. I have been selling nearly every astronomy item I have accumulated over my lifetime, to finance a new imaging system. Unfortunately, The only piece that is in place right now is the Paramount ME. I am waiting for the tube to ship from Germany, and probably won't be back in the imaging business for a few more weeks. In the mean time, I decided to try imaging with my guide scope, which is a tiny Borg 45ED. It does not provide anything close to a flat field on the FLI ML8300 camera, but it has been fun messing around with it anyway. I imaged the Veil Nebula the other night, taking a number of unguided 5-minute exposures in Ha and OIII wavelengths. I created a false color version by assigning the Ha channel to red and assigning the OIII channel to green and blue. I posted it to my gallery at the link below: http://www.slas.us/gallery2/main.php?g2_itemId=5484 <http://www.slas.us/gallery2/main.php?g2_itemId=5484&g2_imageViewsIndex=1> &g2_imageViewsIndex=1 I have imaged all the various pieces of this supernova remnant before, but never at a short enough focal length to see the whole complex. Considering it was taken at a focal length of 325mm and with a scope that was never intended for imaging, it turned out pretty nice. Just don't look too closely! :) Since the corner stars were really elongated, I just blacked them out. Enjoy! BTW - I will be posting images of the construction of my new astrograph over the coming weeks. It is based on a 12.5" Zambuto mirror and a 4" Antares secondary. I now have the van Slyke components in my possession, including a Tri-Cell, Spider, and Toadloader focuser. They are of almost unimaginable quality...truly unbelievable! The tube is a 390mm ID carbon fiber sandwich custom made for me by Klaus Helmerichs in Germany. The tube separates into two pieces for travel using a simple and robust alignment and clamping system that doesn't even need to be re-collimated after separation and re-assembly. I will be using an ASA 3" Wynne corrector, which provides a flat field much larger than my camera's chip. I built a mock-up of the scope to verify dimensions and such, using a double layer of 16" sonotube, but even doubled the sonotube wasn't up to the task. Some of you may be interested in the assembly of the scope, so I will try to upload a few pictures of the components soon, and of the finished scope when the tube arrives. Cheers, Tyler

Thanks, Tyler. I was roped into giving a talk at the library at that time, which I much regret.

45ED Imaging-You’ve Got to Be Kidding
by Dave Gary 24 Nov '12

24 Nov '12

Tyler, I was stunned you could do that with a 45ED. The ONLY resemblance to your astrophoto with the 45ED and ANY of my astrophotos is the vignetting. I’m going to switch to spectroscopy, exclusively, and give up the imaging stuff. It’s too depressing. You are, truly, gifted. Keep up the excellent work. Dave

Science Night Live, 5 December
by Wiggins Patrick 20 Nov '12

20 Nov '12

Coming up on the 5th of December. This is the same speaker who was originally scheduled to speak at SLAS's meeting tomorrow but has been moved to next year. Spying on Our Neighbors with the Hubble Space Telescope http://www.science.utah.edu/outreach/science-night.html Anyone else thinks it's odd that they continue to hold these talks in a place (a bar) where high school and even many college kids can not attend? I seem to remember last year seeing a school bus load of high school AP physics kids being turned away because of their ages. patrick
