1 Frame Wonder M8, M20, & M21

Recommended Posts

Hi all!

After a very long hiatus from anything astronomy I took a vacation and went to the Nebraska Star Party. My main goals there were to do some visual observing with my 20" Obsession Classic telescope from a pristine dark site. The goals were achieved in spades! I took one night there to set up the AT72ED and do some imaging. Well things went wrong all over the place and needless to say due to blue screens and a portable storage device failure I thought I was left with nothing. I did find 1 image that somehow was saved. It was a single raw frame of 180 seconds at ISO 800 with an unmodified Canon T3i. I shot this with the AT72ED on a guided Sky Watcher EQ-6. Image was processed with Digital Photo Professional, Photo Shop Elements 2018, and Astronomy Tools for Elements. After many iterations, I am satisfied that I have pulled as much information out of one frame of data as I am capable of with the tools I have. I tried very hard not to over cook or use to much noise reduction. I was lucky to be at such of a dark site that just one frame held so much information.

Wow, one sub! The question begs, why do we need an hours worth if you are getting results like that with one sub? I was in the U.S recently. I was in San Fran, San Diego and then Tuscon. Tuscon has the dark sky laws for Kitt Peak Observatory, the skies were amazing.

Thanks guys.

I know it is hard to believe that is just one frame so I made a link to to the original CR2 file it came from. I would like to see if you all can get even more from the data than I did with my limited tools. Looking forward to seeing your results.

Very nice Shane. Makes me realize that I did get heavy handed with the noise reduction and saturation! Wish I could have salvaged more of the images. Micro SD card took a dump or I would have had 30 dithered of these images.

30 images like that one would have been an amazing clean final image.

Yeah totally agree with Shane. That light pollution map is good.
