Workflow for STC dual narrowband filter
Is there anything available for a qua-band narrowband filter like the Opt Triad Ultra?
It has the following characteristics:
|Hydrogen-beta||Oxygen III||Hydrogen-alpha||Sulfur II|
I've got very promising results using the STC DNB on Nikon D800a with APP (attached below) and would like to push the envelope even further... Any hints on how to approach quad narrowband on a CFA?
Hello to all,
I need some help here please. My goal is to extract Ha and OIII and then recombine using the RGB tool to an HOO palette but I'm running into issues. I have read and tried the PDF document and the result is a mono image with a mosaic pattern to it which I assume is the bayer array. I've tried a few different things.
First, I my settings in TAB 0 like this, Pattern = Supported, Algo= Ha-Oiii extract Ha
I then proceed to all other TABs and enter the setting, but for this I used defaults as a test. I integrate and I get a mono image with a mosaic. I then go to the TAB 0 again and extract OIII and again I get a mono image with a mosaic pattern.
When I combine in TAB 9 RGB and assign R=Ha G=OIII and B=OIII I get this, a mono image with a mosaic pattern.
Now I tried the normal force CFA and it works. I get a demosaic color image. I've tried to use debayered FLATS and I get this warning,
I've looked around the site for a tutorial and I came up with nothing, probably missed it. So if someone can shed some light on what I'm missing I'd appreciate it.
Forgive me if this was addressed somewhere else, I've been looking everywhere to no avail.
PS Equipment used was STC Duo Narrowband and ASI071 Pro.
I think I found the answer. I'll try it. Thanks
Could you share what you found out? 🙂
I found this under Forum>Totorial and Workflows. It’s for an L-enhance but that filter to what I understand is very close to the STC Duo Narrowband.
