Ralph Copeland, observing on the 72", discovered NGC 2799 on 9 Mar 1874. While observing NGC 2798 he recorded "F, cL, vmE 125.9°, pos 102.7°, dist 97.9" from NGC 2798] or 8.7s f, 21.5" s. The offsets and description are a perfect match with UGC 4909. The NGC position is offset to the southeast as Dreyer used WH's poor position for NGC 2798.

400/500mm - 17.5" (4/6/91): faint, small, elongated 3:1 NW-SE, low even surface brightness. Forms a very close (interacting) pair with NGC 2798 1.5' WNW.

600/800mm - 24" (3/9/13): moderately bright and large, very elongated 4:1 NW-SE, 1.0'x0.25', brighter along a very thin streak of the major axis. Forms a 1.5' interacting pair (Arp 283) with brighter and larger NGC 2798.

900/1200mm - 48" (4/6/13): fairly bright, very thin edge-on, 6:1 NW-SE, 1.4'x0.25'. The disc is slightly warped, bending south slightly near the tips of both extensions. The galaxy is also asymmetric, with the NW end stretched out towards the core of NGC 2798. With careful viewing, an extremely faint tidal tail appears pulled out in the direction of the companion and it fades out just east of the core.
