2017-10-08 Nice Prom

Clear blue skies until the Sun got high enough over houses to image and then BANG cloud appeared from nowhere.  However during a brief break I managed to capture a nice prom. Nothing much on the disk today.

19/09/2017 New camera

I had the first chance to try my new solar camera and here are the results. The camera is an Altair GPCAMv2 130 Mono. As expected from the QE graph this is 20%-25% more sensitive than my previous camera (ASI120MM) & the noise levels appear low. I have also added a 2° dispersion prism, to remove Newtons Rings, to the image train.

Looking at the images there are some marks on the sensor of the new camera, probably from when I cleaned some dust off it. I have now cleaned it again and hopefully removed these, just need to wait for some clear skies to try again.

20/08/2017 AR2671 First animation attempt

My first attempt at an animation, cut a bit short due to cloud. Not great due to newtons rings and poor polar alignment giving image rotation.
