I made a little modify to the Etalon tuning ring so that now I have the “best” setting more at the centre.

Quality is improving and I’m going in the right direction also for post processing. I made a lot of videos today: close ups, full disk, surface, prominences… lot of material to play with.

One thing I notices is the 2 or 3 ghost images I got in full disks. They create a bad effect around the disk making prominences less clear. I have to find out where they came from.

Hardware: Coronado PST + ALCCD5
