AR12719 High Res at 390nm, CaK and H-a in a 280mm scope.

Post by Valery » Fri Aug 31, 2018 9:33 am

Hi all,

August 24 early morning I imaged the sun in H-a, Ca-K and at 390nm UV filter.
Seeing was average.

280mm F/10 standard Celestron equipped with the ARIES 295mm DERF, H-a etalon (alternative H-a eyepiece),
CaK PST filter, Edmund 390nm bandpass filter. Camera Basler 1920-155.

Thanks for looking and comments.

Wonderful images! It is fun and very interesting to see the same region in different wavelengths and to compare structures to see what is visible in which wavelength and how these features correlate. Thanks for showing!

Thanks, Frank

Too bad the seeing can be good enough only during short periods of time and only before the sun rises over 35 degree above the horizon.
