Arp 25 (Gx)

../images/dss/dss2blue_072714.48_+854516.20_5_web.jpg
Image source: DSS II (blue) - 5'×5'
Name: NGC2276, UGC3740, Arp25
Group: Arp114
Type: Gx
Constellation: Cep
Coordinates: 07h27m14.48s / +85°45'16.20"
Brightness / Size: 11m.4 / 2.8'×2.7'
NGC2276 & NGC2300 together are also known as Arp114.

152mm f/8, 171x, Bortle 6, SQM-L 19.3
Not seen for sure at 133x and 171x. At 171x at least an extremely faint brightening was indicated.

FAILED
152mm f/8, 92x, Bortle 4-, SQM-L 20.8
Conditions in the target region: SQM-L 20.7
At 92x quite faint, roundish, very diffuse, almost uniformly bright. The southwestern edge sometimes appears slightly brighter. At 133x not better.

MODERATE
8" f/6, 80x, Bortle 6
Not seen at 80x & 200x.

FAILED
8" f/6, 80x, Bortle 4
Barely seen with averted vision nearby a brighter star as very faint glow.

12.5" f/4.5, 111x, SQM-L 21.3
bei 45x ist die Galaxie indirekt flächig nahe des 8m1 hellen Sterns HD 51141 sichtbar - bei 111x kämpft die Galaxie gegen die Helligkeit des Sterns an, zwischen ihr und dem Stern wird noch ein schwächerer 13m6 heller Stern sichtbar - indirekt wirkt die Galaxie homogen hell und rund - bei 206x wird sie unruhiger, aber echte konkret fassbare Strukturen sind nicht erkennbar

Arp 29 (Gx)

../images/dss/dss2blue_203452.33_+600913.24_12_web.jpg
Image source: DSS II (blue) - 12'×12'
Name: NGC6946, UGC11597, Arp29, H4.76, Fireworks Galaxy
Type: Gx
Constellation: Cep
Coordinates: 20h34m52.33s / +60°09'13.24"
Brightness / Size: 9m.0 / 11.5'×9.8'
Bright spiral galaxy, which is located only 40' southeast of the also evident and rich open cluster NGC6939. Both objects together give a nice view!

B 8x40, Bortle 4, NELM 6m.1, SQM-L 21.1
Fairly faint, round, evenly bright. Less evident with averted vision.

MODERATE
80mm f/6.25, 25x, Bortle 6-, SQM-L 19.5
Roundish, rather faint and less evident brightening.

MODERATE
8" f/6, 37x, Bortle 4, NELM 6m.1, SQM-L 21.1
Large, round, faint, somewhat irregular shape. At 100x I could rudimentarily percept the northeastern spiral arm with averted vision. Overall the galaxy appeared slightly mottled.

12.5" f/4.5, 111x, SQM-L 21.3
bei 45x zeigt sich die Fireworks Galaxy schön in einem GF mit dem OS NGC 6939 - die Galaxie ist noch ohne Struktur - bei 85x ist sie sehr hell und 3:2 elongiert - bei 111x werden Strukturen und Helligkeitsunterschiede erkennbar, von der Sichtbarkeit der Spiralarme wage ich aber nicht sprechen

Arp 114 (GxG)

../images/dss/dss2blue_072940.00_+854400.00_12_web.jpg
Image source: DSS II (blue) - 12'×12'
Name: Arp114
Type: GxG
Constellation: Cep
Coordinates: 07h29m40.00s / +85°44'00.00"

Group Members:
NGC2276 (UGC3740, Arp25) 11m.4 2.8'×2.7' (50°)
NGC2300 (UGC3798) 11m.0 2.8'×2.3' (80°)
NGC2276 is also known as Arp25.

152mm f/8, 171x, Bortle 6, SQM-L 19.3
NGC2300 is with averted vision at 133x relatively well visible, at 171x almost conspicuous. The galaxy appears roundish, moderately condensed. From time to time a stellar brightening appeared in the center, probably the nucleus. NGC2276 was not seen for sure at 133x and 171x. At 171x at least an extremely faint brightening was indicated.

MODERATE
152mm f/8, 92x, Bortle 4-, SQM-L 20.8
Conditions in the target region: SQM-L 20.7

Very nice, uneven pair of galaxies.

NGC2276: At 92x quite faint, roundish, very diffuse, almost uniformly bright. The southwestern edge sometimes appears slightly brighter. At 133x not better.

NGC2300: At 30x very compact, slightly condensed brightening. At 92x and 133x very conspicuous with averted vision, getting significantly brighter towards the center, roundish. From time to time the stellar core appears in the center.

NGC2276: Not seen at 80x & 200x.

NGC2300: Barely seen with averted vision as round brightening.

DIFFICULT
8" f/6, 80x, Bortle 4
NGC2276: Barely seen with averted vision nearby a brighter star as very faint glow. Difficult.

NGC2300: Bright core with faint, round halo. Barely seen with direct vision, very evident with averted vision.

NGC 2276: bei 45x ist die Galaxie indirekt flächig nahe des 8m1 hellen Sterns HD 51141 sichtbar - bei 111x kämpft die Galaxie gegen die Helligkeit des Sterns an, zwischen ihr und dem Stern wird noch ein schwächerer 13m6 heller Stern sichtbar - indirekt wirkt die Galaxie homogen hell und rund - bei 206x wird sie unruhiger, aber echte konkret fassbare Strukturen sind nicht erkennbar

NGC 2300: bei 45x wirkt die Galaxie noch stellar - bei 111x bleibt die Galaxie klein und kompakt und das Zentrum blitzt immer wieder stellar auf - die Galaxie wirkt jetzt deutlich heller, als die Nachbargalaxie NGC 2276 - bei 206x zeigt NGC 2300 jetzt ein leicht flächiges helles Zentrum und sie verliert schnell an Helligkeit zum Rand hin
