At around 200,000 light years in diameter, NGC 772 is somewhat larger than the Milky Way Galaxy, and is surrounded by several satellite galaxies – including the dwarf elliptical, NGC 770, whose tidal forces on the larger galaxy have likely caused the emergence of a single elongated outer spiral arm that is much more developed than the others arms. 
Halton Arp includes NGC 772 in his Atlas of Peculiar Galaxies as Arp 78, where it is described as a "Spiral galaxy with a small high-surface brightness companion".
Two supernovae, SN 2003 hl (discovered August 20, 2003) and SN 2003 iq (discovered October 8th, 2003), have been observed in NGC 772. Both were Type II. 
NGC 772 probably has a H II nucleus, but it may be a transitional object.  [Source:  Wikipedia] 

CAPTURE Information: 
The image was captured with the iOptron CEM120 mount , the venerable Meade 12"LX200 SCT OTA, and my QHY295m Pro mono cmos camera at F7.16 (2182mm FL).  Image subs were taken through Astronomik's broadband filters of Luminance, Red, Green and Blue. 

IMAGE information -- 2022
LUM (300s): 50 subs (4.17 hrs.) on Dec 13th, 20th and24th, 2022.
RED (300s): 30 subs (2.50 hrs.) on Dec 13th, and20th, 2022.
GRN (300s): 28 subs (2.33 hrs.) on Dec 13th, 20th and 24th, 2022.
BLU  (300s): 30 subs (2.50 hrs.) on Dec 14th, 20th and 24th, 2022.

The Luminance subs along with the R, G and B were were shot at 300s and -10C.  All exposures were done at 1x1 bin, Gain 1600 and Offset 56.  Lights, Darks, Flats and Flat Darks were used for processing. 

Processing was done in PixInsight following, for the most part, kayronjm's tutorial of Feb. 24th from several years back. 
This is a slight crop to trim for alignment.

COMMENTS:
This is the 2nd time I’ve run at this target.  The first was in 2017 with my de-forked Meade 12”LX200 OTA mounted to my gone (but not forgotten) Celestron CGE Pro mount, using the Atik 383L+mono CCD camera.
This time we’re on the iOptron CEM120 using the QHY294 pro mono cmos camera.  In each case we employed only broad band filters. 
I was not satisfied with the earlier work and did not even take it to a finished product. I don’t want to cuss this latest, since I am posting it on the Astrobin website.

I had taken approximately 20 Ha subs with the intent of highlighting the star generation in the spiral arms.  However, there proved to be no effective Ha as collected with my equipment.

ONE LAST THING:
My previous postings cover the saga of the CEM120 iOptron mount going back to the Massachusetts service center twice for problematic tracking.  As described, I loosened the RA drive belt and things have improved measurably.  This particular target lost only one (1) sub due to RA excursions.  I have yet to hear back from iOptron since the update on the drive belt adjustment.
