Returned to M56, SYNCed on it. Mounted the D7200 DSLR at prime focus to image the globular cluster M56. Focused on the star Vega, locked the mirror. This is a StarLock autoguided, 30 seconds, ISO 4000, WB 3570K image of M56:
Removed the DSLR, SYNCed on the star Antares, and viewed Saturn, 163X and 325X. Occasionally had some nice views at 325X.
