Taken with a vintage Vixen 102M achromat and a Daystar Quark Combo Chromosphere + a Bresser 2X Barlow and a 90 mm Baader D-ERF energy rejection filter.
Sharpening in ImPPG and PS CC2022.
A flat was created by taking a short video of the defocussed Sun surface. Flat correction was done in AS!3 and worked fine to eliminate the uneven illumination of the Daystar filter.
Good transparency medium seeing
