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 guys, I just got Askar Color Magic C1 and C2 filters. I took one session with C1 and another session with C2. How should I stack them in APP before processing them in PI? I always use one filter session with my ASI533MC so I've never done this before.

Thanks!

Integrate C1 data with 0) algorithm

-- Ha-Oiii extract Ha

-- Ha-Oiii extract Oiii

--> this gives you Ha and Oiii

Integrate C2 data with 0) algorithm

-- Ha-Oiii extract Ha (this produces Sii)

-- Ha-Oiii extract Oiii

--> this gives you Sii and Oiii

 

In PI combine the two Oiii.

Put together Sii, Ha and the combined Oiii = SHO.

 

Hope this helps,

Max

Hi @astrotal & @maxthebuilder,

Or combine the Ha, SII, O3 directly with APP's RGB Combine tool ?

This, of course, works too.

Instead of processing the C1 data to extract OIII and then the C2 data to get the OIII, could you process both C1 AND C2 data together to extract OIII?

@tstevens83  Since OIII only happen in G and B color, I think you can do this with Put all of them together and extra OIII and once. 
But for Ha and SII you need to separate them twice.
