The SE limb
Hi all,
After a 4 months dry spell, on April 21-24 I had a batch of decent
evenings to grab the Moon low above the western horizon.
On April 21 I attended at a local star party, so I wasn’t able to take
several images. This is the only one from that eve. People queued behind
my scope couldn’t wait any longer for looking at Saturn!
Here’s portraied the SE limb under favourable libration including main
craters as Neumaier and Helmhotz (top-right corner), Gill (on middle
top, close to the missing part) and Pontecoulant on the left corner.
The seeing was very variable with nice spells among very poor periods,
transparency quite good.
A severe drift along the DEC axis due to the mounting not aligned to the
pole (the polar star wasn’t yet visible at that time) caused the missing
part and some possible motion blur.
