Error message at end of routines

I maybe tried to have APP do too much. I went back and did Lum and RGB separately. No problem there. Learning as I go.

Yes, you found the correct solution already. This is due to the mixing of mono and RGB which APP doesn't support yet. We do want to make this much easier and not just give a null pointer error. Best is to split the RGB into mono, R, G and B and the register those frames with the luminance.

Ok, but I still have a problem. My L frames and RGB raw frames are the same size, taken with the same scope and optics and orientation bit different GAIN settings (if that is important). If I process separately, how do I register the L and RGB frames to match up before combining as LRGB? When I tried, the L and RGB came out with different dimensions as well.

Thanks-still learning.

@gmillerok1 Once L and RGB have finished their integration, you can clean the file list by clicking the Clean button at the bottom of tab 1. Then you can load the integrated L and RGB files as lights (don't load calibration files and indicate that you're sure when asked by APP) and then go to tab 4 and click the register button. Once done click the Save Registered Frames button. You can then load those registered frames in Combine RGB.

Unfortunately, I was not able to register with the L frame. I cropped them as well to the same dimensions because for some reason the L and RGB dimensions change after integration even though they are the same. I wonder if the different GAIN setting is the issue. But registration with the L frame will simply not succeed. I tried different settings/projections. Nothing worked. At this point, I don't know what else to try. PI registered them without any issue. I guess I can use PI to register but I'd sure like to get away from PI. That's why I bought APP.

@gmillerok1 Can you please upload the L and RGB integrated images to

https://upload.astropixelprocessor.com/

in a new directory called gmillerok1_registration? As always, use upload for both username and password (your APP credentials will not work). Let me know here as soon as the upload has finished and I will have a look at your data. Thanks!

Thank you so much. Files have been uploaded.

Had a go as well, I upped the amount of stars for star analysis to 1000 and set these parameters in the register module;

Then I normalized all frames as well and saved the normalized frames in tab 5, which I then used in the combineRGB tool.

I used these settings, coming from the LHaRGB1 preset and changing those a bit (I also set the multiplier from 2 to 1 for the red channel);

There's quite the amount of color gradients in the data, so that took a bit of careful light pollution correction;

With that done, I proceeded to star color correction. This is tricky when using filters, but worked pretty nicely here;

Which resulted in this;

Which I think is a really nice one. 🙂

Thank you again. I was able duplicate those efforts for registration where  APP was not able to do so before with those parameters.

I had previously tried to increase the number of stars but this had not worked. I presume it was that value as well as the parameters in registration that caused APP to fail at registration before.

Registration was the only issue I ran into but thanks for taking it to the end-now I have something to duplicate as part of the learning process with APP.

Is there any way to make a HDR image using shorter exposure frames? I have some 30 second exposures I want to use to bring out the core a bit better.

Thanks again for you much needed assistance to help me with APP. I can not express my appreciation enough.

Unfortunately this is not possible yet in APP but it is on the TODO list to be added.
