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 it 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.
I am either doing something wrong or trying something that does not work in APP.
I am imaging the Rosette Nebula with two sets of captures, all with the same scope, camera (ASI294MCP), exposure, gain, bin, offset, temp.
For one set of lights captured with an Optolong L-Pro, I spit the channels into R, G, and B in the Calibrate tab and integrate each separately.
I integrate a separate set of lights captured with a 7mm Ha filter.
When those 4 integrated channels are loaded in the Combine RGB tool, it gives the error message that the frames are not the same size.
The size of all raw light frames is 4144x2822.
The size of the split channel RGB frames is 4136x2814 and their separate integrations size is 4131x2819.
The size of the integrated Ha frames is 4143x2843. I have tried different algorithms in Tab 0 for the Ha frames but get the same result.
(If I integrate the OSC frames without splitting out the channels the size of the integrated result is 4138x2827.)
Is there anything I can try to be able to get my Ha channel to line up with the RGB channels in the Combine RGB Tool for it to work?
Thanks,
Jeff
@jhart You can load the R, G, B and Ha integration results as lights in tab 1 (do not load any calibration files) and then go to tab 4 and click the Register button. When done, click the Save Registered Frames button at the bottom of tab 4. Those you can load into the Combine RGB tool.
Hi Wouter,
Thanks for the reply. I will follow that and save the Registered files at Tab 4 and try again.
Is the following procedure basically correct for preparing the 4 channels for the Combine RGB Tool?:
Tab 0
RGGB
Airy Disc
Tab 1
Untick Auto-detect Masters & Integration (other boxes unticked too)
Load the 4 integrated (and calibrated) R, G, B, and Ha files as lights
Don’t load calibration files
Tab 2 Don’t need calibration because all files are already calibrated
Tabs 3 and 4 as usual
Tab 5
At the bottom of the Normalize panel under save normalized frames:
Click to apply registration to frames
Set Save Directory to know where they will be.
Click save normalized frames button.
These will be the 4 channels to load in the Combine RGB Tool.
Tab 6 Optional
Can do an integration of all 4 channels if desired to create a synthetic luminance
Set the parameters as usual
Set Save Directory to know where integrated file will be
Can click to integrate
Creates a single integrated file that can be used as a luminance.
Thanks again,
Jeff
@jhart In general you can leave all at their default values. APP will sort it out by itself.
Thanks Wouter,
I think the process I was following did not get the registration done properly. To do that correctly I understand that I should stop after Tab 4 and take those four registered channels to the Combine RGB Tool as follows:
Tab 1
Untick Auto-detect Masters & Integration (other boxes unticked too)
Load the 4 integrated (and calibrated) R, G, B, and Ha files as lights
Don’t load calibration files
Tab 2 Don’t need calibration because all files are already calibrated
Tab 3
Tab 4
At the bottom of the Register panel under save registered frames:
Set Save Directory to know where they will be
Click save registered frames button.
These are the 4 channels to load in the Combine RGB Tool.
I followed this and the Combine RGB Tool worked great.
Thanks again,
Jeff
@jhart Glad you figured it out. Once again, though, you don't need to untick any boxes in tab 1.
Hi,
Another question about preparing the integrated channels for the Combine RGB tool. Should they be normalized after being registered, or just registered for loading in the RGB tool?
Thanks.
