Empty sun in H-alpha

The activity of the sun is very low and there's not much to see.


This is part of today's equipment testing campaign. I got a new Quark under warranty and this one, while being mechanically better, does not show protuberances nearly as well as the previous one. Hopefully there will be some sun spots coming up so I can see if this Quark produces better surface detail than the previous one.


D-ERF, 80/480 APO, Quark, 0.5x reducer and ASI178MM. 5000 frames, full resolution and bin2. Best 5 % is stacked.


Imaged at lat: 60° 13.1259'
