M13 (May 2017)
Well, here is a close-up of the great globular cluster in Hercules. This is 15x300" with the CFF290 Classical Cassegrain and SXVF-H9C, shrunk about 8%. The great photogenic thing about M13 is that none of the stars are bright enough to blow out the pixels in a 5-minute exposure, yet that same exposure captures some pretty dim stars. Great target!
