Session:  PEC Test Run

Detections: 

Submissions: 

Tonight I only checked the adjustments I made to the mount and PEC training.  The PEC seemed to help a little, but the scope and CCD is limited to about a 45 second exposure - unguided.  I took several 1 minute exposures and about half of them showed slight trailing.  I think with some further "very fine" adjustments in the polar alignment, the unguided exposure length will slightly increase.  I took a series of 45 second exposures of M27 and M57 and the images can be seen below.  The temperature tonight is supposed to drop to near 50F but it's partially cloudy outside.  The Orionids meteor shower is also tonight and if it clears, the All Sky Camera should pick up a few of them.

Messier Object M27 - The Dumbbell Nebula (~ 20 - 45 second exposures)

Messier Object M57 - The Ring Nebula (3 - 45 second exposures)
