Part of a Leo Triplet Mosaic I'm working on. My FOV is just too small to get all three in frame with decent composition. This is fairly tightly cropped - the sensor size is 4096x4096.

Happy with the detail I'm getting inside the galaxy! I found that bringing down the highlights before going non-linear and then applying two different scales of un-sharp masking brought the most detail.

14 total hours L26 R20 G26 B16, all 600 seconds. A super-luminance was used.
