Armed with my new Baader Cool Ceramic Herschel Wedge, a William Optics Megrez 72, a DMK 21AU04.AS Mono camera and a Astrotrac mount, and at last being blessed with a gap in the clouds, I decided to capture some solar images this afternoon. Â The DMK reached focus easily with the ClickStop in place on the Herschel Wedge, but didn’t have enough in-focus using a Tele Vue 2.5x Powermate, so the images below are as prime focus, and then using a cheap Meade 2x barlow.
The WO Megrez 72 is f6 so the image size isn’t as magnified as I would like, so time to start saving for a larger refractor. Â Images were captured with IC capture (native software supplied by Imaging Source with the DMK cameras) and stacked in AVI Stack 2. Â 3000 frames used from 4000 captured.
Closeup of one of the sunspot groups (AR1731) taken with an additional 2x barlow placed between the Baader wedge and the DMK camera. Again 3000 frames used from 4000 captured, stacked in AVIStack 2.
Thanks for looking, Steve
