UGC 4609 - Spiral Galaxy (PGC 24779)

UGC 4609 (Lynx) Ring Galaxy, J.Lowrey List Alias: PGC 24779 (catalog mag +15.3) Target imaged using incorrect target offset of  W 0',  N -2.5' which had the effect of moving the offset glare star even closer to the field centre. (Target to be rescheduled with a target offset of  W 0',  N 2.5' in order to move the bright offset star out of the field of view as originally intended )

UGC 4609 - Earlier Detail  (2020-10-25) Trace of ring structure is potentially just visible in image below, but is difficult to prove due to glare from mag +8 star HIP 43280 Target to be repeated with a target offset of  W 0',  N -2.5' in order to move  the bright offset star well out of the field of view. The galaxy in lower left of image is PGC 213535 (catalog mag +16.9)
