Messier 34 NGC1039 is a lovely open cluster in the constellation Perseus some 1,500 light years distant, with an estimated 400 member stars. It subtends about 35', one moon diameter, giving it a radius of about 7 light years.

From a paper: SPECTROSCOPY OF STARS IN THE GALACTIC CLUSTER NGC 1039 (M 34) PHILIP A. IANNA° The Ohio State University Received March 23,1970

The brightst members of this cluster are B-type main-sequence stars (B V). B-type stars are extremely luminous and blue. These stars have from 2 to 16 times the mass of the Sun and surface temperatures between 10,000 and 30,000 K.

I had some extra time in the early evening and decided to finished data collection that I started a few years ago still only a few frames six each RGB for (18) total. This combines data from 2012 taken while camping at 9.000' with remote observatory data taken more recently. All integration used the home made 8" F/2.6 astrograph.
