Hello all,

 

This popular group of four galaxies is known as Hickson 44.

It's in Leo, not too far from Algieba (gamma Leonis).

NGC 3190 dominates the central area, with the elliptical

NGC 3193 to the upper left, and the irregular (tidally-stretched)

NGC 3187 to the immediate upper right.  The interesting

barred spiral/ring galaxy NGC 3185 sits below these

three nearer to the bottom of this image, like a pendulum

in about the 5 o'clock position.  The group is roughly

25 Mpc distant.

 

OTA: 314mm Harmer-Wynne f/5

Camera: ASI 1600 (hence the ugly bright-star artifacts)

Exposure: About 3 hours of Luminance, and 35 minutes each of RGB in 5-minute subframes

Filters: AstroDon E Series Gen 2

Mount: Astro-Physics Mach1GTO

 

Down-sampled to ~33 percent, yielding about 1.5"/pixel

Always a nice target to see.  Well done.
