Solar Observations 26th May 2017

Not only was the evening observing good at the last RAG meeting, earlier in the day afforded the opportunity for some Solar observing. Although we are approaching the next Solar minima, there was a sunspot group present and some prominences were visible. The prominences were more of the spicule type that are very short lived and at the end of the imaging session the prominences recorded had disappeared, checking on GONG time-lapseĀ  these prominences appeared and disappeared.

First 3 images taken in H alpha using Coronado PST and DMK41 mono CCD, best 50 of 1000 frames stacked in Autostakkert, wavelets in Registax 6, Photoshop CS^ for combination of disc and prominences, colourising and final tweak.
