Processed my latest data on Messier 100 together with nearby edge-on companion NGC 4312 in Virgo.

This field is packed with faint background galaxies from the Virgo Cluster and turned out to be one of my favorite galaxy fields this season.

I tried to keep a balance between preserving faint galaxy detail and avoiding an overly sharpened look. Feedback welcome!

Seen edge-on from about 25 million light-years away, NGC 4631 is a highly active spiral galaxy shaped by gravitational interaction with nearby companions.

The turbulent star formation inside the disk drives enormous clouds of gas and dust far above the galactic plane, creating the faint halo visible around the galaxy.

Captured remotely from Spain with a PlaneWave CDK17 and ASI6200MM Pro over 22.6 hours of RGB integration.

My latest image of Messier 64, the famous Black Eye Galaxy in Coma Berenices, located ~17 million light-years away.

What makes M64 particularly fascinating is that its outer gas disk rotates in the opposite direction of the inner region—likely evidence of a past merger with a smaller galaxy.

My latest deep integration of the Whirlpool Galaxy (M51) captured from Fregenal de la Sierra, Spain.

This dataset combines broadband LRGB with 15 hours of Hydrogen-Alpha to reveal star-forming HII regions across the spiral arms and in the interacting companion NGC 5195.
