H-alpha solar images

1. 2 images taken with a Lunt 50mm solar scope and an Altair 178M Hypercam. Best 30% of 2000 frames for surace and promenences. Region of interest selected giving me a frame rate of around 140 frames per second. I was getting around 50 frames per second at full resolution. I knew I needed a new laptop!

2. 1 image taken using Jim's Quark on an Altair 80mm f7 telescope and a GPCam. It's got larger pixels than the Hypercam so better suited to longer focal lengths. The Quark has an integral 4.2x barlow. Best 25% of 1000 frames surface and prominence. I did get some of the prominence showing on the surface image.

All videos stacked in Autostakkert!3 and surface ones sharpened in IMPPG. Images tidied up, coloured and combined in PS3.
