Details:
Normally I expect good and stable seeing conditions under a clear morning sky. But this pair of images tells a different story - even around noon time the air can be really quiet! That´s why these SolarContinuum-filtered and CaK image look so sharp. I used a TS115mm triplet refractor and a TeleVue 2.5x PowerMate to extend the focal length to 2,012mm, the camera used is a QHY533M.
