| 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. |
