Mar 28 2026 APP 2.0.0-beta40 will be released in 7 days.
It did take a long time to have the work finished on this and itĀ will have a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration. We extensively optimized many critical parts of APP. All has been tested to guarantee correct optimizations. Drizzle and image resampling is much faster for instance, those modules have been completely rewritten. Much less memory usage. LNC 2.0 will be released which works much better and faster than LNC in it's current state. And more, all will be added to the release notes in the coming weeks...
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.
Hello,
I'm getting ready to process a project on Abell 39 and I used my IDAS NBZ dual narrow band filter to collect all the data. I'm wondering what is the best algorithm to process this data. My guess is the Ha/OIII Color algorithm in tab 0.Ā
I had also thought that I could do a HOO using this data too but I've never done that so I don't quite know the workflow for that algorithm. I looked in the "Tutorials & Workflows" forum but didn't see anything unless I just missed it.
Any advise would be very much appriciated.
Thanks!
Dale
@dalepenkala Hi Dale. If you simply are looking for a basic HOO color image then the Ha-OIII color im age indeed is best.
If you want to be able to create your own HOO image, meaning you want to play with the contributions of Ha and OIII to the various color channels, then Ha-OIII extracht Ha followed by Ha-OIII extract OIII would be best. For those, simply load your data as you normally would and select the Ha-OIII extract Ha algorithm in tab 0. Then go to tab 6 and click integrate. Then return to tab 0 and select Ha-OIII extract OIII and immediately return to tab 6 and click integrate again. You will be asked if you want to renomlize the images to which you should answer yes. When done you can go to the Tools tab and select "combine RGB" to create your own HOO mage. You can use the HOO 1 or HOO 2 formulae for that and then play with the sliders until you get the result that you want.
Hello Wouter,
Ok thank you for your response. I kinda figured that would be the process but just wanted to get confirmation on how to do it.
FYI I was able to get this done and I also used both file formats per our PM and everything worked out great! I did just as you told me 😀Ā
Here is the result.
