Sombrero galaxy

One of my favorite galaxies out there. I love the shape and the shadows that it's tilt casts.
I captured this with the CHI-3 100cm telescope. It is an advanced request of an RGB image with one hour total exposure time. 2 subs 600sec each for every color channel.
I love the quality of this telescope.
I used AstroPixelProcessor for stacking and stretching the data and also for the RGB composition. Then I processed in photoshop which utilized further stretch, per channel noise reduction, sharpening, bad pixel removal, luminance masking with a differently edited stretch to ninimize noise and emphasize the halo without burning out the core. I also applied some color balancing and a faint color grading.
I love how well it turned out with only a single hour of exposure.

My favorite Messier too!
How did you remove the bad pixels in photoshop (filter dust&scratch or ...)?
