when you look at M34 it’s most appealing feature is the mass of multiple stars on view. I have details of those in M44. Open clusters are mainly young stars .
New stars are formed in the gas and debris loaded arms of spiral galaxies, you can observe new stars in the Trapezium of the Orion Nebula.In the early universe star formation gave a ratio of binaries to triples of 60:40. Later this evolved into a ratio of 65 binary : 25 triple : 35 singles. Gravitation pulls apart open clusters , one of the biggest we can see is Ursa Major . The whole of the plough is a moving cluster apart from the first and last star.
I got the whole wide view , but found a more detailed drawing showing the main multiple stars. Just using a 4″ scope , these are very accessible.
Next time I”lol use some more magnification to get these stars and increase the contrast. I also had look at Sigma Cassiopeiae, a lovely delicate view, under clear skies ! Nick.
