New Image - Veil Nebula Complex in Narrowband
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
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:

Thanks Patrick! The ME looks ridiculous with that <2" scope sitting up there. I hope it can handle the load. :) Tyler -----Original Message----- From: utah-astronomy-bounces@mailman.xmission.com [mailto:utah-astronomy-bounces@mailman.xmission.com] On Behalf Of Wiggins Patrick Sent: Friday, November 23, 2012 12:30 AM To: Utah Astronomy Subject: Re: [Utah-astronomy] New Image - Veil Nebula Complex in Narrowband 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.

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.

Thanks a lot Don. It has been fun messing around with a tiny scope, but I am ready to get the new astrograph up and running. I haven't imaged much since Kanab, and I haven't even finished processing images from that trip yet. Life has been hectic, especially with the passing of my dad and all the related issues of getting my mom situated. I hope all is well with you. Cheers, Tyler PS - Congrats on all the great images recently. Your work is excellent. -----Original Message----- From: utah-astronomy-bounces@mailman.xmission.com [mailto:utah-astronomy-bounces@mailman.xmission.com] On Behalf Of Don J.

Thanks Tyler. Most of what I know about imaging I learned from you. I hope the new astrograph meets all of your expectations. Have you had a chance to put the ME "through its paces"? Is it as good as advertised? -----Original Message----- From: utah-astronomy-bounces+djcolton=piol.com@mailman.xmission.com [mailto:utah-astronomy-bounces+djcolton=piol.com@mailman.xmission.com] On Behalf Of Tyler Allred Sent: Saturday, November 24, 2012 10:52 AM To: 'Utah Astronomy' Subject: Re: [Utah-astronomy] New Image - Veil Nebula Complex in Narrowband Thanks a lot Don.
