[Solved] OIII / SII Dual Band Filter
Have you seen the new OIII / SII dual band narrowband filter from Altair Astro?
If I had one of these, would the Extract Ha debayer algorithm extract the Sulphur data?
Hi Daniel, @daniel-tackley
Did not see it yet, thanks for sharing 🙂
Yes, Ha extract would then extract SII.
Also Antlia and Askar released similar products.
Antlia - Hb+Sii
Askar - Oiii+Sii
I am thinking of getting one of them and was wondering about how to separate those channels.
@maxthebuilder Its the same as with Ha/OIII filters: Red channel SII, Blue/green channel: Hb or OIII
I would get the OIII/SII filter, because there you can add integration time to OIII, which is also in the OIII/Ha-filters. Hb is normally just the same as Ha but in blue/green. Dont know why Antlia dont have an OIII/SII filter...
Yes, I was thinking along the same lines. Will get an Oiii/Sii.
