Hi all,
It was almost a year ago, 2018 May 31. A dwarft AR12712 was seen on the disk. To be honest, this group was a group of pores, not spots. See here how small was this AR

I managed to take some images of this AR in CaK and H-a. In a large 11" telescope this group looks much more impressive and was very busy (in H-a).
The telescope was C11 280mm F/11 SC equipped with full aperture ARIES tri-band DERF filter and Quark Chromosphere etalon and CaK filter. Camera was Basler ACA 1920-155 with IMX174 chip.
See how much more impressive CaK images vs boring white light typical images. And compare how much more impressive H-a image vs image in the CaK.
Seeing was good at times, but not really excellent. I have recorded about a dozen of movies in each wave length and selected two best ones.
Thanks for looking.
Valery
