M65 (NGC 3623)

Telescope: Planewave 17" CDK reflector, 1940 mm FL
Camera: FLI-PL6303E, 3072 x 2048 pixels
Exposure: Lum:12x3 minutes. Processed with PixInsight.
Location: Mayhill, New Mexico (Elevation 7380')
Image Center (J2000): RA 11h 19m 10s, Dec 13° 04' 22"

Intermediate spiral galaxy, part of the interacting Leo Triplet and the least disturbed galaxy of the three. Apparent size 8 x 2, mag 10.2. The galaxy's tight spiral arms, intricate spiral dust lanes and lack of prominent spiral arms indicate a low amount of interstellar dust and gas and consequently make it less visually interesting than many other galaxies although M65's disk appears slightly warped. The galaxy core is visible although some foreground stars lie in front of the galaxy. There are about 40 small galaxies in this image brighter than mag 20.
