Mosaics of different scales and cameras

Which APP version are you using?

I would first try to combine the small fov with the overlapping frames you have for that panel (making a new panel out of that) and then try to create the mosaic with the panels.

@vincent-mod I’m using 1.083.2. Just downloaded it on my Mac yesterday. 

so I’m trying it on the 2 panels now. One wide field that contains the crescent Nebula and the narrow one as well. 

still getting the same error 🙁

the ones to be specific. No matter what I try I get these errors. 

Mmm, would you be able to upload the data to our server? Like 10 lights per panel and your master calibration files should be enough.

@vincent-mod Thanks. Just uploaded the file into tunarob-mosaic-different-FL-issue folder.

Tried to keep the names self-explanatory.

For 1000mm I uploaded the stack and 10 lights (don't have calibration frames for it). For 400mm I uploaded the stack, 10 lights and both master dark and flat.

I'm having issues with combining them both in a mosaic mode, so didn't upload the rest of the panels.

But I managed to successfully integrate a mosaic from Redcat (scale ~3.5) and 400mm (scale ~1.95). Maybe my 1000mm stack is corrupted or something?

Thanks for the upload, I'll have a look today!

Just to verify, I see your master calibration files have the xifs format, which is PixInsight data. I'd advice to create masters in APP itself as that will work much better. I also can't use them for analysis here, do you have regular fits formats for these? Preferably created with APP?

Unfortunately I only have them coming from Pixinsight as that's what I use for stacking. 

Just uploaded .fit masters as you requested.

In my tests, I was able to successfully create a mosaic out of 4 panels using my PI stacks and masters. The only thing that's failing is when I try to add in my 1000mm FL image to it.

Ah ok, thanks for adding them. If you could then upload 10 raw darks, bias and flats as well that would be very helpful. Using masters from another application is not a good idea when processing in APP as it expects its own calibrated data, which differs in some ways to others.

Good to know, thanks 🙂

Uploaded 10 darks and 10 flats. No bias. They're for 400mm photos just in case - 1000mm no calibration at all.

Ah ok, well for proper flat calibration you'd also need either bias or darkflats. 🙂 So without bias or dakflats I can't really use the flats properly. That shouldn't influence the mosaic creation though, so I'll use the darks and the other data you have.

Ah, I think I see what's happening. Part of the data is RGB and part is mono, this will indeed cause issues in normalization as APP can't (yet) process both at the same time. In a next version this should be possible. This means that for this data, you'd need to split the RGB data first into mono data channels, using "split frames" in tab 2, all the way down. Calibrate and then save the frames. This will give you R, G and B data of that panel. Using one of those should then work properly in the mosaic. Of course, you'd want to combine these with RGB data of your own, but then you first need to have that as well.

With the RGB data, I think you can also first do an "extract-Ha" step, in tab 0 in the algorithm tab. Switching to that algorithm and then loading in the RGB data, will give you a mono H-alpha image immediately. Save those image as H-alpha, then restart APP, load in your data together with the now H-alpha data and then create the mosaic.
