Hickson 34 (GxG)

../images/dss/dss2blue_052147.00_+064100.00_5_web.jpg
Image source: DSS II (blue) - 5'×5'
Name: Hickson 34, HCG34, Arp327
Type: GxG
Constellation: Ori
Coordinates: 05h21m47.00s / +06°41'00.00"

Group Members:
NGC1875 13m.7 0.8'×0.7'
PGC17173 b18m.3 0.2'×0.2'
PGC17175 b17m.1 0.4'×0.2'
PGC17176 b17m.4 0.4'×0.2'
Southeastern of the dominant NGC1875 are the three much more fainter members, which are arranged in a curved chain.

8" f/6, 216x, Bortle 5+, SQM-L 20.9
Conditions in the target region: SQM-L 20.3
I've only tried the bright NGC1875 of course: Altitude of about 40°. Appeared round, almost evenly bright, difficult to hold with averted vision.

bei 131x ist NGC 1875 indirekt als zarte Aufhellung sichtbar - bei 160x blitzt der Kern mitunter etwas heller hervor
MODERATE

8" f/6, 150x, Bortle 4+, NELM 6m.0+, SQM-L 21.1
Conditions in the target region: SQM-L 20.4
Roundish with somewhat brighter center. Fairly well perceptible with averted vision, but not evident. Altitude of only 30°.

NGC 1924 (Gx)

../images/dss/dss2red_052801.97_-051838.33_5_web.jpg
Image source: DSS II (red) - 5'×5'
Name: NGC1924, H3.447
Type: Gx
Constellation: Ori
Coordinates: 05h28m01.97s / -05°18'38.33"
Brightness / Size: 12m.5 / 1.6'×1.2'

Only 2 degree west of M42! Very faint, appeared roundish, evenly bright.

12.5" f/4.5, 160x, SQM-L 21.3
Conditions in the target region: SQM-L 20.5
bei 85x ist die Galaxie als schwaches diffuses Nebelchen zu erkennen - bei 160x ist sie dann eindeutig sichtbar - der Kern ist leicht aufgehellt - die Galaxie bildet mit zwei schwächeren Sternen ein flaches gleichschenkliges Dreieck
