Fully Multi-Threaded LNC, many improvements for the registration engine, platform upgrade, and further tuning of internal memory consumption and memory release back to OS.

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.

I expected this to have been asked before, but if so I can't find it:

 

Is there a way to extract Ha and OIII from a dual band Ha-OIII filter with OSC in one go, or do I first have to do "Ha-OIII extract Ha" through integration, and then the same process over for "Ha-OIII extract OIII"?

 

TIA

We do want to improve this for automation, but currently it's selecting this manually and then processing again. The color algorithm combines them.
