Today's H-alpha sun. Seeing was not great, due convective cloud that is fairly typical of my neck of the woods (Sydney)
this time of year.

Re: Ha Disk November 19 2022
Thanks. Looks like I'll be retiring my 9Mp Point Grey/FLIR camera due the new QHY533m having a square format 1" sensor, almost double the frame rate, with no read-out artifacts, that you typically get with brighter objects and a CCD (similar to blooming). The cooled sensor is also a plus. The PGR would typically heat up to well over 40C. The QHY533m comfortably sits at zero, to -5C depending on the ambient temperature.

Superb picture.
I do not look at the sky with the eyes of an astronomer, but of a person looking for the beauty of nature.
