Hi Peter. 24 x 210 second light frames, but 40 would be much better. f/5.6 - you will get iris diffraction spikes. There is a lot of detail missing, it could do with reprocessing. The camera has been modded with a spectrum enhanced filter - that is the IR filter has been removed and replaced with an Astronomic filter.

There are several ways of obtaining good focus, a basic method is using live view at 10x magnification, focusing on a bright star until the diameter of the star is as small as can be. Focus at f/2.8 and then stop down to f4 or f5.6.
