First attempt white light sun spot


This is my first attempt at solar imaging in white light. 

Date of image 12/07/2016

Equipment: SW Skymax 150 (f12) with a TeleView 2x Barlow lens. The telescope was mounted on an EQ5 pro. Camera: Canon 550D in 640x480 movie crop mode set at 1/60s exposure ISO400, the frame rate was 60fps. 

The total movie duration was about 2 minutes (clouds were very frequent and heavy). Stacking the frames was done with RegiStax 6. I may have overdone some of the wavelets as well (I'm still getting used to Registax!).

Some first comments: The telescope was tracking reasonably well considering I only did a rough PA and the FoV was so small. I tried my best to properly focus but in the 1 minute of imaging I may have not got exact focus.

The image shows some stacking artifacts probably because some frames used cut off the sun spot.
