Clean Sun October 7th 2017

The weather hasn't been right for any astronomy so far this season. But today, the Sun was shining, so I had to give it a go. Obviously, it has been some time since the last time I did any solar imaging. The camera wasn't very square in the telescope. Hence the left side of the image is a bit out of focus. Not much going on on the surface, but a nice little proturberance.

Tech det : Lunt 35mm H-alpha telescope, ASI178 camera, Gain 0, exposure 1.5ms, FireCapture for imaging, AS!2 for processing and Registax for wavelet sharpening. Final touchup in Irfanview.
