Total eclipse La Silla Observatory July 2nd 2019

I used an 8 bit cmos camera (the camera itself is 14 bit, but I only used 8...) this time to take photos of the eclipse. It was obvious when I was processing that I had limted range of values to work with. But after a few attempts, I managed to get this. Not my best image of an eclipse, but ok. I will attempt more later. Click on image for full size.

Tach details : ASI178MC camera, gain 100, exposures from 0.5ms to 2s. SkyWatcher Evoguide 50ED telescope on a SkyWatcher StarAdventurer. FireCapture for capture, Gimp 2.10 for processing.

Images from Namibia with short exposures.


 I had brought my new ASI071MC Pro cooled camera to take photos with, but I also brought an ASI178MC uncooled camera. Mostly to take photos of Jupiter, but I also wanted to try it out on deep sky. And I did dedicate one entire night for just deep sky photography with this camera using short exposures. And the images came out quite good. So maybe I will use the camera more on another occasion. All the images are through a Williams Optics 98FLT with a WO AFR-VI reducer-flattener. ASI178MC camera. All images about 1 hour total exposure. Stacked with DSS, processed in Gimp.
