Observations of the NGC 2805 group in Ursa Major
My observation of the January's Galaxy of the Month back in January 2017.
Positional sketch of the galaxies around NGC 2805 by Andrew Robertson with a 60-cm F4.5 Newtonian, 13mm Ethos eyepiece giving x208. I’ll type my scribbles: 00:30 hrs, 27th Jan 2017, 600mm F4.5, e/p 13mm Ethos giving x208. Seeing Ant II-III, misty low down, 21.1 SQM at time of observation. NGC 2805 low SB. The larger and smaller edge on GX’s (2920 & 2814) stood out more. Small companion to larger edge (2820A or IC 2458) was AV1. Designations identified the following day.
Inverted close-up of the positional sketch made in the notes. Andrew Robertson - 2 January 2021

Galaxies in Ursa Major from Kelling Heath Star Party 2016
Andrew Robertson (Norfolk) and his 600mm Newtonian on a driven Dobsonian mount were at Kelling again this year.
Observed with an 8mm Ethos for a power of 340x under Antoniadi II-III Seeing and NELM of 5.7 and 21.35 SQM.
With Ursa Major overhead Andrew made observations on Monday night of a couple of galaxy trios. Please click on the image of his observing record for a larger version that may be easier to read.
NGC2820 (1), NGC2814 (2) and IC2458 (3)
NGC2857 (1), NGC2856 (2) and NGC2854 (3)
