H-alpha solar imaging on June 14th

A tilt mechanism was put together from a ZWO T2 tilt adapter plus a C to T2 adapter.

A nosepiece was attached and the lens from a Cemax x2 Barlow was attached.

The tilt is introduced into the light path to prevent Newton’s rings from appearing on the image from a CMOS camera.

A QHY 5L-II-M was attched to the tilt assembly which was then placed at the prime focus of a Coronado Solarmax II, 60, BF15 H-alpha scope.

The equipment setup

AstroDMx Capture for Windows was used to capture two 1000-frame SER files, one exposed for the disk and the other exposed for the prominences, which were very small.

The best 20% of frames from each SER file were stacked in Autostakkert!3, wavelet processed in Registax 6, combined and post-processed in the Gimp 2.10.
