Koehler Urban Astrophotography

 09/08/2024 -- Testing the venerable Celestron 10" F4.7 Newtonian on the Celestron CGEM DX on the dolly with the Svbony 405cc, the Baader RCCI Rowe Coma Corrector and no other filters.  Initial configuration completed on 09/07, but found the balance wrong. Rotated the OTA in the rings to position the camera & finder facing down towards the mount.  This showed immediate improvements with a rapid calibration in PHD2 as well as within the Indi/Ekos guider calibration tab as well.  Conditions were reasonable with no moon and clear skies. Clear Dark Sky seeing forecast for 09/08-09/09 showing no cloud cover but marginal seeing conditions expected. Indi Allsky camera pseudo-sky quality metric captured on 09/08/2024 around 11pm showing a jSQM of ~4600 at 11 (dropping to ~4300 at 11:50pm). Meteoblue seeing forecast for 09/08-09/09/2024 showing few clouds expected overnight. Started a capture of 40x60s lights on NGC 6960 (Western Veil Nebula) in the scheduler set to run until 2:45am...
