NGC 2683 is a field spiral galaxy in the northern constellation of Lynx. It was nicknamed the "UFO Galaxy" by the Astronaut Memorial Planetarium and Observatory.
It was discovered by the astronomer William Herschel on February 5, 1788.
It is viewed nearly edge-on from Earth's location in space and is located about 30 million light-years away, although previous estimates also give distances between 16 and 25 million light-years.
NGC 2683 is receding from Earth at 410 km/s (250 mi/s), and from the Galactic Center at 375 km/s (233 mi/s). [Source: Wikipedia].

The image was captured with the iOptron CEM120 mount, the venerable Meade 12" LX200 SCT OTA, and my QHYCCD QHY294m Pro mono CMOS camera at F7.16 (2182 mm FL)
Astronomik's Lum, Red, Green and Blue broad band filters were used.
Image Information -- 2024
LUM : 78 subs (6.50hr) on Feb 5th and 12th.
RED : 17 subs (1.42hr) on Feb 5th.
GRN : 19 subs (1.58hr) on Feb 5th.
BLU : 20 subs (1.67hr) on Feb 5th.
All exposures were at 5 minutes (300s) each, 1600 gain, 56 offset, 1x1 bin and -10C.
Processing was done with PixInsight, following (for the most part) Kayronjm's tutorial of Feb. 24th from several years back.
Lum filter was used to develop the Luminance image. R, G and B were collected for the color mix.
North is to the right (pretty sure), and this is a slight crop due to better placement of the image.
Comments:
This is the 1st time I’ve run at this target.
ONE LAST THING:
The iOptron CEM120 mount RA excursions continue to annoy, but are being dealt with. However more recently, the system as a whole has been flaky upon startup, requiring lots of reboots and plugging/unpluggin USB cables.
I was able to diagnose the problem as being caused by a faulty 10ft. USB cable that connects to the Lodestar guide camera, the Atik EWS2 filter wheel and the Starizona Microtouch focuser controller. Replacing that cable mostly fixed the problem.
