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 

http://www.solarham....1_2018_disk.jpg

 

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.

Very nice captures Valery.  Very detailed and well processed. waytogo.gif

 

I'm still learning.  Are both images at the same scale?  In the Ca K it is easier to see the 4 pores.  In the Ha I find it a much more interesting wavelength although a bit harder to pick out the pores locations.
