Description

After breaking my full spectrum converted Sony A6000 after it dropped to the ground,  I decided on a used ASI183 MC Pro as a replacement.  At first I struggled with the new smaller sensor, and it was another learning curve.  My Skywatcher 72ed was not focusing correctly, and losing focus when shifting targets.  I didn't know if the focuser was damaged.  After some tutorials online, I rebuilt the focuser by taking it apart and adjusting the tension.   I feel this shot is the culmination of all the efforts to re-start my setup.  Good news is with a fully cooled astrocam, I should have reduced noise and I can create a dark library so I spend less time than when I was using a mirrorless camera.
