The region around NGC7635, the Bubble Nebula, has a number of other interesting targets, such as NGC7638, Dreyer’s Object, which is an active star forming region containing what is reported to be the largest protostar so far observed at 300x the size of the solar system (!) with a contracting core of 85-115 solar masses. (http://astronomydraw...citing.html?m=1).
Also in the same frame is the open cluster M52; HII region Sh2-159; dark nebula LDN1231 and irruptive variable star V628 Cas classified as a Herbig Be star which has strong outflow of matter.
The clouds cleared long enough the other night for me to collect 2h 36m of data.
