Description

This image I have a two page list of notes on.  The mount worked perfectly, probably the best time ever.  I was able to pull 5 min subs with the Radian filter.  The dew heaters worked, the laptop worked, everything went well. EXCEPT the camera.  It got so cold that the USB and power plugs constricted and had connectivity issues.  Somewhere in the middle of this run I had a cable snag and did not catch it before it ruined an hour of images. Many of these evenings with short data capture had something go wrong resulting in a tear down in frustration.   This image was 20 subs each 300 seconds.  I was even able to get darks, flats and calibrate the lights!

Reprocessed with the new tools and software, I now have a baseline to use to get better. All things considered, I am very happy with this image.
