Solar imaging from 1/11/15

After imaging with the Olympus E-PL5, I decided that I would try my hand at imaging with the Celestron Neximage 5 with a 1.25″ 0.5x focal reducer on the Daystar Quark. I had removed the protective UV/IR cut filter and was hoping that this would help with the Newtonian rings phenomenon.

Sadly the Newtonian rings are still present, and I had not done flats to subtract these out from the images. Worse of all, the horizontal band which appears on the Neximage 5 was very much visible in the image, which affects the image capture unfortunately. But here are the images I managed to capture – all 1 minute videos at 2×2 bin, processsed with PIPP, AutoStakkert! 2 and Registax.

Unfortunately the Neximage 5 is a poor imager for h-alpha, and I do not think I will be using it for this purpose again. May have to look for the ZWO ASI174MM imager, as it should work very well for H-alpha solar imaging (and also lunar, planetary and DSO).
