Lunar Images, Current
March 1, 2020 After a protracted absence while recuperating from a knee replacement, Chewie and I made it out to the
observatory tonight. Seeing was only average, but I took two sets of 14 thirty second videos of the moon using the ASI183MC camera at the f/11 focus of my C14. An exposure of 0.77
msec was used to take the videos and 280 frames were in each video. They were processed using Autostakkert 3, keeping the best 15% of the frames. The resulting stacks were sharpened
with wavelets using Registax 6 and composed into a mosaic using Photoshop Elements. Finally, 4 different images of progressivly brighter levels were saved out and converted into an HDR
image with Photomatix Essentials. The image displayed above was obtained from the second set of videos taken against the last part of twilight. Click on the image to expand it to full
screen. The clipping from the region around Theophilus, Cyrillus and Catharina below shows that reasonably good resolution was obtained in spite of the seeing. Also, see the region
around the craters Aristoteles and Eudoxus.
