Second attempt last night. Above average seeing.
Focus was better and didn't change all night noticeably.
But there's always something conspiring against me
High cirrus cloud drifted in and got worse close to midnight.
I got frame 3 done just as Eta Car was totally closed out.
I think because of the cloud, I had to do slight brightness
adjustments to merge the images. (on Jan 18 version I did not
have to).
The Fickle Finger feature turned out well also, thanks Mike S. for
the tip
Also attached is part of Humunculus maybe showing with a slightly
different curve applied to Eta C.
