I have 61 light frames from the same OSC camera and telescope. I was following Eric Astro's Hubble Palette with OSC and APP. I followed the steps exactly 3 different times, but each time, when I select the RGB combine under tools, assign the 3 channels that were created earlier and click (re)calculate I get and error. "The images aren't compatible. Please make sure the data has the same dimensions and bit depth." If I look at the 3 files loaded it seems the Oxygen III channel dimension is different. Any idea why it is doing this?
Did you do a Analyze Stars and Register on the three stacks before trying to combine them in Combine RGB?
@wvreevenYes
@wvreevenYes
Wait, I may have answered to quick. I did that as part of the stacking process of the three, are you saying I should do an Analyze Stars and Register on the three "completed" stacks. prior to doing the RGB combine?
Yes indeed. Though as to why the OIII stack is one pixel smaller than the other two, I don’t know. But you could crop the three frames to the same size, then run them through Analyze Stars and Register, save the registered frames and then load them in Combine RGB.
I did what was suggested to the 3 completed stacks, the OIII still came out different. I will try cropping.
Thanks
