Cluster:    Abell 278 Tri (Abell distance class 3)
Site: Sölden, Tiefenbachgletscher (Austria), 2800 mtrs. over sea level 
fst: 7m,2
Instr.: 457/1850-Newton
Mag. 276 ×, 308 ×
Description: Rich galaxy cluster, although it contains only faint objects. The brightest galaxies in this area (1 - 4) are situated outside of the clusters border. Many galaxies are extremely difficult even under excellent alpine sky conditions. A compact central region (about 4' × 4'), quite similar to a difficult HCG or SHK compact group. It consists of only three but very difficult galaxies. Some MAC objects at the very limits of visual detection, however objects no. 8 and 12 suspected only. 

GUIDE lables MAC 0157+3224 as "PGC 7350" and MAC 0157+3214 as "PGC 7346". Another galaxy - PGC 7346 - is identified by MegaStar, but only a 15 mag nonstar in GUIDE. Nonstar's are no. 7 and 12 also. Object no. 3 is PGC 7448 and 11 is PGC 7348. MegaStar chart shows four (!) galaxies labeled as MAC 0157+3214. Only one of them - C, situated close to E to PGC 7349 (9) - seems to be visible.
