B 40mm, 8x, Bortle 4-, NELM 5.7+, SQM-L 20.9
Evident, round, diffuse brightening with rather compact, brighter center. Several stars seen with averted vision, background still diffuse. Somewhat smaller than M38. Together with M37 & M38 an awesome view.

8" f/6, 37x, Bortle 4
Good contrast to the surrounding. In comparison to M37 and M38 fairly poor with some brighter and fainter stars arranged in chains. Slight concentrating toward the middle.

Awesome under dark skies. Under light polluted skies the cluster gets more lost due to its fainter members.

B 40mm, 8x, Bortle 7, NELM 4.5, SQM-L 18.9
SQM-L 18.5: Barely visible with direct vision, relatively large, diffuse, somewhat brighter center.

B 40mm, 8x, Bortle 4-, NELM 5.7+, SQM-L 20.9
Evident, round, relatively large, diffuse brightening with somewhat brighter center. Not resolvable. Together with M36 & M38 an awesome view.

|
4.5" f/8, 28x, Bortle 6-, NELM 5.0, SQM-L 18.9
Evident, but overall quite faint. Many fainter members visible with averted vision, similar in brightness, almost evenly distributed.

120mm f/5, 18x, Bortle 6, SQM-L 19.3
At 18x central star quite obvious, cluster itself appeared more as a granulous, almost round brightening. At 50x well resolvable with many faint members.

8" f/6, 37x, Bortle 4
Very evident. Extremely rich with mainly fainter stars. In the center a brighter, orange colored star is evident. Poor regions within the cluster, stars itself arranged in groups and chains.

B 40mm, 8x, Bortle 4-, NELM 5.7+, SQM-L 20.9
Evident, almost evenly bright, irregular shape. Some stars seen with averted vision, otherwise diffuse. Somewhat larger than M36. Together with M36 & M37 an awesome view.

B 70mm, 15x, Bortle 4
Altitude of about 13°. Similar to M36, but larger and fainter. Relatively evident, diffuse, not resolved.

80mm f/6.25, 20x, Bortle 6-, NELM 5.0+, SQM-L 19.6
Concentrated toward the center with radial star chains, so that the shape of the cluster appears irregular. At 50x there was an apparent star in the center with no stars in the direct vicinity (like a hole in the center).
|
EASY
|
4.5" f/8, 28x, Bortle 6-, NELM 5.0, SQM-L 18.9
Rather faint members. The cluster is more dominated by star chains, so it appears more irregular.

8" f/6, 37x, Bortle 5
Quite concentrated toward the middle, star rich, mainly moderately bright and fainter stars.

80mm f/6.25, 50x, Bortle 6-, NELM 5.0+, SQM-L 19.6
At 20x quite small, diffuse, slightly oval brightening. At 50x I could saw two stars (probably the two stars at the south edge) of similar brightness, otherwise the cluster appeared very diffuse.
