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.
[Solved] How to combine ha data to rgb osc image using different cameras.
I have watched one of Mabula's tutorials on how to stack different images from different setups with success. However, I am unsure on how to integrate mono HA data from a different camera, to the split rgb channels of the osc camera.Â
My understanding is that I need to use the combine rgb tool once I have split the rgb channels, but how do I go about preparing the HA data in readiness for combining to the rgb channels.
The scales are 2.65" per pixel for the mono ccd & 1.85" per pixel for the OSC.
Ok, so if I stack them all together must I load the two different sets of calibration frames all in together. Or calibrate both sets seperately then load both sets of calibrated light together ready to stack together?
I thought you wanted to inegrate (as in stacking) Ha from OSC with Mono Ha.
But if you mean integrate Ha in RGB Making a HaRGB palette. Then it is Done in the Edit tab in APP. So. In that case, you need load the RGB stack and Ha as lights in APP first. Register and save the registered files. Split the RGB data and save those files. Load the registered Ha, R, G and B  and combine them. APP is not the first choice of software for this action. I would rather use PI.
Hmmm After "I split the RGB data and saved those files. " You should load the registered R and Ha in Tab 1 and stack them. The "problem" is that you have used triband filter. The R channel contains both Ha and Sii. You will now have a new stacked combined channel (R+Ha).
Combine This new channel in as RGB. R is now (R+Ha), G och still G and B is still B. But you will now have a better R signal. Time to edit 🙂

Stefan, thank you very much for your help here.
Ryan, I would suggest the following workflow to make this happen:
load your RGB exposures and calibration frames to make the RGB integration/stack. Use Multi-Band Blending (MBB) with 10-25% to reduce artefacts near the borders of the field of view.
Then clear the frame list in 1)load with the clear button
load your mono Ha frames with calibration frames and make the H-alpha integration/stack. Again use MBB 10-25% for the same reason.
Now you have both the RGB and the H-alpha stack, so again clear the frame list panel in 0) load and then load both the RGB and H-alpha stack as lights. These 2 stacks need to be registered and also normalised now. Register with dynamic distortion correction in 4) register if it is needed, meaning that you want to enable this if the stars will not perfectly align after registration of the 2 stacks. In 5) Normalize, enable advanced normalization and normalize the 2 stacks. At the bottom of 5) Normalize, save the normalized frames with apply registration of frames enabled.
The saved registered and normalized stacks are now fully compatible to be loaded into the RGB Combine Tool to make a nice HaRGB composite. If you still have issues with the borders then crop the problem area away like earlier suggested.
I have just attempted to combine both stacks following your instructions, although there seems to be a slight improvement it still looks poor.
Is there anything else I can try or should I cut my losses? 🤔
To be honest there doesn't seem to be that much of an improvement adding the HA data from a much older ccd camera (starlight xpress H18 mono) to my Altair Astro 26c CMOS camera.
If you want I could take a look at your stacks and see what the problems might be. Email the links to the two stacks to download to Stefan@digitaliz.se

I am glad my instructions were of some help here. Yes, I see the issues that are there in your screenshot. I think with more tweaking in the RGB Combine tool things can be improved still.
Please try the following options:
to have the sky background match between the Ha and RGB data, play with the bg sliders a bit (bg is short for background). It might improve things a lot a think.
Which data has the best quality in general? If it is the RGB data, then use that as well for the luminance layer, so increase the L slider for the RGB data then and play with the amount to see the changes after pushing calculate. If the H-alpha is better than RGB, set that as L
in terms of the actual colors of the composite, you can still try to play more with the contributions of Red, Green and Blue. So modify the R.G,B sliders in value and check what happens.
