Re: Book Recommendation- 15 Million Degrees

Lucie Green's book (2016) complements and in places updates Jack Zirker's book Journey from the center of the sun (2002). Both really good reads.

Re: Testing a Calcium corrector on a C11 (New image added 27Dec)

Your calcium corrector certainly gives great results, I wonder how it would perform with a refractor.

Re: AR2791 & AR2790 | HA & 395nm | Dec 8th 2020

Always enjoy looking at your images and really appreciate all the info you provide. I see from a post on another forum that you are using an Altair Astro 395nm filter, do you find this better than the Baader K-line filter which appears to be very similar in passband and transmission?
