Hello, just starting with APP and Ifairly novice in astrophotography. I took 43 x 4 minutes frame of the Orion belt (canon 70d full spectrum & 200mm f2.8 prime lens ) . Not sure what went wrong in the process (see image below ) it looks like 4 images mis aligned.

I don't see an image in your post, please use the "attach files" link under the reply box.

Ok, that's not normal indeed. What APP version are you using and did you leave everything on automatic settings? What exactly was your workflow, from you data and in APP?

edit: I do see that in the image there are no values for the stars and quality etc. I also see that the exposure of the subs is at 0 seconds, so something is wrong here with the data. What did you use to capture the data and are these the RAW files or already processed somewhere else?

I am using version 1.082. I have loaded raw files (canon Cr2) directly from Sd card. It worked before...

@vincent-mod my work flow is simple : load lights and calibrate frames directly from Sd card and leave all the settings as they are

So you're working on the SD card itself, is that also your working directory? If so, that would not be advised as it's way slower than a regular harddisk and I can imagine for the amount of work APP does on disc, it may cause issues.

@vincent-mod . Yes maybe you are right . Will transfer everything on hard disk. Still funny though that I tried four times from SD card and four times same results . Will try again from hard disk and let you know

Yes, not sure this is the issue, but at least I know this wasn't a correct workflow. So to get to the bottom of the issue, a good starting point is nice to have. 🙂
