Sunspot AR2266

On my day off on Tuesday, as there was clear skies around 1pm I decided to take my telescope out for some solar imaging. The seeing has been fairly poor since the start of the year, which poses a particular problem when imaging at 9000mm effective focal length (900mm, 5x power mate, 2x crop factor of Micro 4/3rds camera).

Hence I decided to be less ambitious and use my Skywatcher ED80 in the setup so the effective focal length was 6000mm (600mm, 5x power mate, 2x crop factor). I found that the best images were taken at 1/2000 to 1/4000 sec (better than my 1/8000 sec images).

The images below are two of the best single exposure images I have managed to get of the Sunspot AR2266 – probably the best images I’ve managed of the sun this year. My aim is to get the fine details of the sunspots at very magnified views.

With the sun rising higher into the sky in the following moths, I’m hoping that I will be able to do some serious solar imaging and get some nice sunspot images.
