Hi Tyler, I did not know what a Borg 45ED was so I goggled it and found: http://www.optcorp.com/product.aspx?pid=4178 That you are able to get such great images with just a 45mm scope (most binoculars are bigger than that) just blows me away. I look forward to seeing what you do when your new setup is complete. patrick On 23 Nov 2012, at 00:14, Tyler Allred wrote:

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:

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

Hi Tyler, Great image and amazing field size. -----Original Message----- From: utah-astronomy-bounces@mailman.xmission.com [mailto:utah-astronomy-bounces@mailman.xmission.com] On Behalf Of Tyler Allred Sent: Friday, November 23, 2012 12:14 AM To: utah-astronomy@mailman.xmission.com Subject: [Utah-astronomy] New Image - Veil Nebula Complex in Narrowband Hi all.
