A faint, feathery solar prominence was the best the sun had to offer last week.

A rose colored sun captured on March 8, 2020 and processed today (Easter Sunday). The little disruption at lower left is active region AR 2758, identified by its reversed polarity to be a member of new Solar Cycle 25. Its appearance reminds us that activity, while still deep in the bottom of the curve, will return on the sun and on the earth too. A rosy and hopeful Holiday to all.

Three views of the magnificent solar active region 2192, which adorned the earthing facing side of the sun 5 years ago this week. Top-white light, middle-hydrogen alpha light, bottom-Calcium-K line light.

Have you ever done a writeup or a guide to your image processing techniques. I am a (very) novice solar astrophotographer - mostly h-alpha, and would love to improve my image processing. Thanks, and I love your work.

Thanks very much. I have given talks on this and will be speaking at this year’s Starfest in Ontario. There are links to my TEDx talk and a short video about my work linked here: http://www.avertedimagination.com/main1.htm

Hi just wondering what equipment you are using to get your solar images. I am currently using a sv80st with a daystar quark chromosphere filter. I get great surface detail but no prominence (I guess daystar works very well as advertised). My guess is you're using a Lunt, they're the only scopes I've seen that get that quality blend of chromo and prom.

I use a c.2000 Coronado 90mm solarmax etalon. You can see pictures and links to more info on the equipment here: http://www.avertedimagination.com/img_pages/little_big_man.html
