Description

No luck again with the weather, so far could just get data from one night. Hope to add more exposure time but forcasts are not good.
NGC 7538 is home of the largest Protostar known so far.

Main target has been the little bright NGC 7538 with a huge but faint emission nebula to its north and northwest. As the field with this scope and camera combination has been large enough, I framed it so the famous Bubble Nebula and open cluster M52 are too in the final image.
