Description

Another proof-of-concept for long focal length imaging using a guide scope. Five minute subs at 3910mm focal length, f/11. I'm pretty happy that the stars are reasonably round (close to the limits of seeing). I'm also very happy that the central star is visible. No flats, darks, etc. used for this image.
