Observations of the NGC 750 group in Triangulum
My observation of the September's Galaxy of the Month with a 60-cm F4.5 Newtonian, 8mm Ethos eyepiece giving x338 and a 18’ field of view (FOV). Magnitude 5.5 skies, Ant III, at 02:15 UT on the 2nd September 2019.
The 750 group was pretty straightforward. I identified 6 galaxies in total (NGC 736, NGC 738, NGC 740, NGC 759, NGC 751 and NGC 761) ranging in magnitude from magnitude 13.1 to magnitude 15.9. NGC 750/NGC 751 is Arp 166.
NGC 738 was almost stellar with a bit of 'fuzz'. The group was spread over half a degree so with the 8mm Ethos (x340) used to observe them I had to move around and missed ngc 739 (magnitude 14.9) and NGC 733 - dubious this one re mag etc. MegaStar5 and Sky Tools 3 give slightly varying magnitudes.
Positional sketch of the galaxies around NGC 750 by Andrew Robertson with a 60-cm F4.5 Newtonian, 8mm Ethos eyepiece giving x338 and a 18’ field of view (FOV). The double star I noticed which I estimated to have a separation of 2" - 3" was A 1920, magnitudes 9.4 and 9.2 with a separation of 1.7".
N.B. Having since read Harold Corwin’s notes he states NGC 733 is almost certainly a star.
