June 14, 2017: Quick early disks and Ca-K proms


Recommended Posts

Git some data just after breakfast. Seeing not brilliant, but the new AR swinging into view, so a set up the scope, snapped the data and rushed to work. The data has been stacking quietly, and I now have the first results.

WL, grey scale:

I also made a longer exposure Ca-K shot for proms:

Best seen at full resolution. H-alpha data are still stacking, and I will see if I can get more Ca-K prom detail later
