Moon - very good seeing (20221030)For almost one week already, we have very good seeing here in the Alps, with a theoretical resolution of 0.6 to 0.7 arc seconds: These are rare conditions which built up right in time for the
Partial Solar Eclipse 2022 on 25th this month, 5 days ago. I haven't noticed such a good and long lasting seeing period in my ~2 years astrophotography journey.
I captured 3 videos of 1000 images each from a tripod, less than 2 minutes each. From the first video (AVI) the 60 best images were aligned and stacked by
Planetary System Stacker[i] [/i]and post processed (histogram and sharpening tweaks only) by
ImPPG.
From this result I believe it is the most I can expect from the used equipment, in particular the 17+ years old
Canon EF 1:2.8/300 mm lens with the same aged
Canon EF TC 1.4x giving a mere F=420mm focal length only, shot wide open at f/4.0.
Side note:While the excellent seeing still lasts today and the young moon (after the eclipse) still doesn't disturb the dark nights, I had no chance to do some
deepsky imaging these days (nights) because there were always high thin clouds (cirrus mostly) covering extended regions of the sky. One night I tried it nevertheless and could capture images for 4hrs + 3 hrs (7 hours of data) but only received nice round stars with at best only a tiny hint of some nebulae I intended to capture – after stacking and stretching.That was annoying.
