Very good H-alpha SHG imaging conditions -- 10 June

Post by thesmiths »

Conditions were very good early in the morning and also quite stable so I collected a lot of data. The following image corresponds to 90 GB of SER files (30 full disk scans). Technical details and other versions of the data are here: viewtopic.php?t=41173. Click on the first image to see at higher resolution. To see the second image at full resolution you need to open in a new tab.

There were some technical problems when I tried to do Ca-H. Here is the top and bottom portions of the solar disk (there was a issue with the portion in the middle). The top one shows the fairly large prominence on the right side.

Superb photos.

I do not look at the sky with the eyes of an astronomer, but of a person looking for the beauty of nature.

WoW, I am blown away! SHGs rule, that's for sure. The second, negative full disc is totally impressive!

Two thumbs up!!!
