Compact with well defined edges. Very bright.

EASY
B 50mm, 7x, Bortle 8, NELM 4.0
Despite of massive light pollution (city & half moon) and large exit pupil of 7mm I could easily see M3 with direct vision as a quite small, but bright nebula.

EASY
70mm f/5.7, 22x, Bortle 6, SQM-L 19.2
At 22x quite conspicuous with very bright, well defined center, getting much fainter towards the edges. At 57x the outer parts appeared slightly granulous with averted vision.

SKETCH

EASY
80mm f/6.25, 25x, Bortle 7
Apparent with direct vision due to the bright, well defined center. Outer regions much fainter. At 62x the outer regions seemed slightly granulous.

EASY
102mm f/11, 125x, Bortle 6-, SQM-L 19.2
Very nice view. At 125x the outer parts were quite well resolved and the cluster appeared granulous close to the center. With averted vision I could also glimpse some individual stars.

EASY
4.5" f/8, 50x, Bortle 5

The whole cluster appeared clearly granular, the edge areas were very well resolved. Many individual stars were visible with averted vision close to the center. The edges appeared irregular due to star chains.

EASY
8" f/6, 37x, Bortle 4, NELM 6.0
Extremely bright center. Outer regions granulous. At 150x the cluster was resolvable close to the center, especially the outer regions. The center was still granulous.

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.
