M16 -- Eagle Nebula


I was at Kentucky Camp this summer with Charles and I only focused on one target.   So, this is 20 x 30 min of H-alpha stacked and processed in PixInsight, but also tweaked a little in Photoshop.  Taken with the Explore Scientific 80mm F/6 refractor and the Atik One CCD.

I have color data from the T3i taken through the Tak.  So, my next dreaded step is to figure out how to register this H-a image and combine it with the color image.  I know I can do it in theory...

NGC 281 ...what a pain!

From the Mountains of Madness...






NGC 281, aka Pacman Nebula...


I'm completely not happy with this image.   24 x 10 min exposures, Canon T3i, 1600 ISO.  Scope was the Tak TSA-102 at F/8.  So much noise and noise reduction that it was a miserable experience.   99% PixInsight, 1% Photoshop.   Probably about 40 hours of processing for this meagre image.

It's my fault that I didn't get out there again and collect another 2-3 nights of data.  That would
have made it much easier to process, and I would've had much more detail.

Yes, I'm aware of the halos around the bright stars!   Yes, I could put in another 3-6 hours to get the halos under control, but I'm exhausted and need to move on...

I still have a M16 image to process, but after that, I'm hoping to retire the T3i.
