M101 Luminance - Nocturne Observatory

Hi all. I got another good night and decided to image M101. Again, I spent the entire night collecting luminance, but this time I went for 10-minute subs. I combined 34 for this image. I attached a reduced version. For the full version, take a look here...

Be sure to click the image a few times to get to the full version. I think this one is worth taking time to look around. There sure is a lot to look at in this image.
Cheers,
Tyler

That's tasteful.
Here's another vote for the monochrome, Tyler.
What do they say "Everything that was old, is new again"?
This image sure has the legs to stand on its own.

Really Nice, it is amazing what a 5.1 APO with a CCD can see!

Compare some of the faint galaxies seen through the arms to a Hubble image and you have captured many small, faint and very distant background galaxies. Your long (10 min) exposures also reveal the extent of M101's arms. I wish the nights were longer and weather better so we can gather more photons.

Thanks for sharing.

Ty, That looks super! Processing in PixInsight by any chance? It has the look of their HDRWT algorithim. Very nice!
