Description

A hard target for me in Bortle 7 with all the humidity this year.  Rejected 80% of the subs.  Nonetheless, could get better detail with the C11 than could have hoped for with my 5" refractor.

From Wikipedia:

NGC 925 is a barred spiral galaxy located about 30 [4] million light-years away in the constellation [url=mw-redirect=https://en.wikipedia.org/wiki/Triangulum_(constellation)]Triangulum[/url]. The morphological classification of this galaxy is SB(s)d, [3] indicating that it has a bar structure and loosely wound spiral arms with no ring.[6] The spiral arm to the south is stronger than the northern arm, with the latter appearing flocculent and less coherent. The bar is offset from the center of the galaxy and is the site of star formation all along its length. Both of these morphological traits—a dominant spiral arm and the offset bar—are typically characteristics of a Magellanic spiral galaxy.[7] The galaxy is inclined at an angle of 55° to the line of sight along a position angle of 102°.[3]The NGC 925 is a member of the NGC 1023 Group, a nearby, [url=mw-redirect=https://en.wikipedia.org/wiki/Gravitationally_bound]gravitationally-bound[/url] group of galaxies associated with NGC 1023.[5] However, the nearest member lies at least 650,000 ly (200,000 pc) distant from NGC 925. There is a 10 million solar mass (M☉) cloud of [url=mw-redirect=https://en.wikipedia.org/wiki/Neutral_hydrogen]neutral hydrogen[/url] attached to NGC 925 by a streamer. It is uncertain whether this is a satellite dwarf galaxy, the remnant of a past tidal interaction, or a cloud of primordial gas.[8]
