White Spots west-limb (19/07/2016)
Date of image 19/07/2016
Equipment: SW Skymax 150 (f12) at prime focus. The telescope was mounted on an EQ5 pro. Camera: Canon 550D in 640x480 movie crop mode set at 1/1000s exposure ISO400, the frame rate was 60fps.
I wanted to capture some solar detail near the limb of the Sun, I saw these light spots so I thought of capturing those. I did not ramp up the wavelets because I was getting ringing effects at the suns horizon. I also did not like the smoothen effect of the de-ringing feature in Registax.
The total movie duration was about 5 minutes. The weather was great for solar imaging. The best 25% of frames were selected and decompressed by Pipp, Stacking and editing was done with RegiStax 6. I used about 15 alignment points.
The telescope was tracking well. Focusing was done by trial and error (by slowly tweaking the focus and watching 15 seconds of live view).
