The Sun - 27th May 2020

[David Smith]

Clear-ish skies today. A bit of high cloud so took the AR102 out initially and grabbed white light and Ca-K full disks. Conditions seemed to improve a little and the seeing was ok so I grabbed the Evostar for some more fun. Managed to get a full 6 pane FD and some proms so worth the effort.

Nothing doing in white light but I had the AR102 on the mount and can do an FD so ....

Then on to the Ca-K full disk. The usual 6 pane pano processed with more tone-curve shenanigans for a partially inverted view which just about shows some proms if you look hard. I quite liked the mono version so here are both the mono and false colour versions. After tinkering with Firecapture the other day I can shoot in 16 bit now so this is 6 x 500 frames @ 16bit which equates to about 30GB of data! That took AS!3 a while to process. Not entirely sure 16bit is giving me anything extra so will try and do a 16 vs 8 bit comparison at some point.

 

 

Lastly some prom, shot binned as is commonly the case at the moment as this seems to work well.

Clouded up soon after this session so glad I got on with it!
