Final color Calibration with eXcalibrator. This image is a straightforward LRGB
combine with Luminance layering. Final Image size is
approximately 2000x1494. North is to the
upper right in this image. NGC1023 in the upper left and lies in the
constellation of Perseus. IC 239 is in the lower right and lies in the
constellation of Andromeda. The Perseus / Andromeda border cuts diagonally from
upper right to lower left. A close inspection of NGC 1023 reveals a blue
"smudge" on the upper end. This is the companion NGC 1023A. This
smaller companion galaxy is thought to be interacting with the larger NGC 1023. This
pair is also known as Arp 135. IC 239 is a face on spiral galaxy hiding
among foreground stars of our own Milky Way. NGC 1023 is estimated to be 34
million light years distant from Earth; IC 239 is estimated between 30-40
million light years distant. Horizontal FOV is 55'
Image center is approximately - Equatorial 2000: RA: 02h 38m 18s Dec: +39°01'30"
