AR2824 and AR2826 my contribution May 27, 2021

Post by ffellah »

Hello all: after seeing all the magnificent images posted, I could not resist not imaging these two sunspot groups before they reach the limb. I took a half hour this morning before work. Seeing was not helping, as we just had a storm last night over southern New England, so lots of humidity in the air and warm weather. I tried using the sodium Quark, as it seems a bit less sensitive to seeing conditions.

Franco,
I have always liked the Sodium D line images. They often seem sharper and more contrasty than similar continuum images. I read that they capture the transition layer between the Photosphere and lower Chromosphere and adds a bit to the detail seen in continuum. I think Helium gives a similar view.

I hope to see you image in sodium more often.

Thank you Alexandra, Rainer, James, Ivan and Maurits for your kind words. I was pleasantly surprised the image made SPOD :) . Will try to use more the Sodium etalon going forward.

Thank you Brian and Martin for your nice comments. I used an Explore Scientific 152mm achromatic refractor and the FLIR Grasshopper 3 174 chipped camera. I shot 40 Gig of data, out of which only 1 Gig was used.

Nice and interesting capture, Franco. Looks like it worked out great despite the lesser conditions.

Clean looking setup as well.
