Yesterday evening I could sketch the wonderful pair of craters Atlas and Hercules with charcoal and chalk on black cardbox. This was the second sketch I did of these craters. I had a look into my archive and compared the current sketch with the one done on May last year.
Both sketches have been done with my 5” Celestron MAK. What we can see is the different lighting conditions based on moon age and libration. Furthermore, the seeing conditions last time have been much better than yesterday – I could not go up to 300x yesterday but had to leave it with the 7mm EP.
The real difficulty with this sketch was not to see the object in the eyepiece, but mostly the cold temperature (below -20C with humidity and wind). Unfortunately I couldn’t see the nebula, probably mostly due to its large apparent dimension
