Moon 91.4% (+) - A mineral test mosaic (3 panels) of the south-west (Schickard to Ptolemaeus)
During the night of May 2nd, I was working to get the C11 EHD operational (
see the story on the previous image). First thing, I aimed the C11 manually at the moon to configure the focusing/EAF (first crude manual focus, and then fix the EAF to the focuser)
Before trying to sort out polar alignment and the guiding, as a quick test, I took a couple of short video’s of the moon with the ASI2600MC. A bit short on frames (only 250 frames stacked), so this isn’t crystal sharp, but the aim was mainly to get C11 EHD step-by-step operational. The mount was only roughly polar aligned, so the moon was drifting a bit in the image (only allowing some short videos) and the ASI2600MC was running in USB2.0 (very low fps)
Four videos/images captured, three of them matching into a mosaic (the fourth as a separate post, if it is any decent). Quickly processed, and as this is a colour image, I decided to squeeze out the mineral colours, although the capture was a bit short on frames. Initial mosaic, and cropped/mineral version uploaded
Colours are perhaps a bit over-saturated and not 'deep' enough because of not enough frames captured. The moon looks like a big rusty rock. Considering these are test shots, I’m reasonably satisfied with the outcome ... especially given that this is nearly the only thing I'm able to capture these days because of the bad weather.
