AR12546 in CaK 22nd May
I was really surprised at the quality of the seeing when I got the 100mm Tal100R refractor out at 7am on the morning of the 22nd. It's not very often that it works this well at 100mm aperture but today was of those days! Taken at 1750mm focal length with the home brew CaK filter and the PGR Chameleon 3 (IMX265) camera.
