Nicely done Aaron, that shows a lot of detail! Love to know your method; very impressive!!
All the best,
Wow Thank You Mark !
I only just the other day decided on a name for what I do as I now call it spectroheliofiltergraphy or the practice of using colour filtered pixel groups to hyper tune custom arranged colour and other filters stacks to specific broadband and narrowband wavelengths via my own specially modified photographic wedge and array of filters ...
This method lies between single double sided and coated glass filters like you use for
Ca k and something like the multi stacked elements of a quark.
The three elements preventing me so far from sharing all I know are that the solar imaging crowd is a bit stuck in mono sensor land and my methods and filters are developed specifically for and with colour cameras in mind while using one for every phase of experimentation, testing & development.
The second is wedge modification, I run a 1.8nd in my wedge and employ a 1.25 nd filter set to adjust exposure over a broad selection of light intensities and plan to add a 1.2nd next season and eventually hit zero point neutral density in my solar wedge allowing for proms in some of my filtered wavelengths.
The third is a composite of reasons, one being the site I share all these methods and recipes on and how handing off information to enable individuals to save thousands on filtering the Sun and have way more flexibilty and fun might not go over so well
with some and there will likely be the that talk of the parasitic light seen in my filters and I see it too comparing my 100 dollar filters to thiers that cost thousands...
Then the final points of the 3rd composition being interest or when my imagry gets noticed enough for other SH's to invest themselves knowing all production filters have slight bandpass differences and there are capture methods germain to success to learn as well.
Getting the Idea Mark I thought a little about how to handle the first compliment of this nature.
