There are probably a few more non-stellar items in this huge 4deg x 4deg FOV, but those in the title are the main objects.

So here is the next STX image, but Ha only to demonstrate the camera's response given its 20% increase in efficiency at 656nm over the STL. 15 minute subs were used for a total of 4 hours exposure. The 65mm Baader Ha filter has a bandpass of 7nm.

Thanks!

P.S Under 4feet of snow here so plenty of time to catch up on the processing.
