Sun in Ha in Cak - 4 June 2021

Post by smerral »

Cak done with the Altair Astro 60 EDF stopped down to 40mm and the Lunt CaK B600. DMK31 camera.
Ha is a 7 pane mosaic done with the double stacked Coronada PST and Altair GPcamV2 mono.
This latter camera actually gives me horrendous, closely spaced newton's rings, which are even visible in CaK. Fortunately the FFT filter plugin in Photoshop easily removes them.
Seeing was not great, especially for the CaK.
