Description

Test with C8 and unmodified stock DSLR continues with ISO1600 and 2 minute exposures, no filters, no calibration. In spite of a scary guide curve in PHD2 the stars in the center are looking pretty good. Next time three minutes exposures?

M8, M20, M16 and M17 are the jewels of Sagittarius in that I am planning to take more images of them until they vanish out of view.

Rev B: Caldwell 76 in Scorpius, 20 frames each 120 sec exposure at ISO1600, no filters, no calibration no noise issues.
