Update on the 2.0.0 release & the full manual
We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.
Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.
Hi all,
I have a question for the new available dualband filters for SII/OIII
How do we seperate the SII from the OIII, using the Halfa-OIII extract
Halfa for SII?
Just in case I get myself such a filter I'd like to know
Thanks for any feedback,
Mert
You treat it just as if was Ha. So use the Extract Ha algoritm to extract Sii.

@digitaliz-se Thanks Stefan, that's what I imagined since the central band wavelength is
very similar between halfa and SII
What about an SII/OIII color image? Â Like the Ha/OIII color. Is that possible? Â Thanks.
Hi Richard.
See above: Treat it as Ha/OIII - and rename to SII and OIII.

I have the Altair 6nm Combo, and following exactly this, I successfully generate:
- Ha and OIIIa from my Ha-OIII Filter
- SII and OIIIb from my SII-OIII Filter.
I then register OIIIa and OIIIb to OIII and have my 3 Narrowband FITS.Â
Stacking is really good (best) in APP - for all other I use PixInsight.
You need to carefully (re)name, and assign the right flats, darks and bias.
Thanks Michael, that's good to know!
