Hi. I am an absolute beginner with APP but have been processing data for a few years now with Pi. I really like the look of APP for pre-processing and I want to get into mosaics.
I got data last night from M31. I am using an Esprit 100 with a 294MC camera driven by an iOptrom GEM 45.
The subs are 120 second with a LPro filter (full moon and I have bortle 8 skies). I use EKOS for capture and have captured 25 subs for each corner in a 2x2 matrix. I have Darks, Flats and DarkFlats.
When I integrate (default settings) I get this. Left are 25 integrated subs and right is an individual sub that has only been debayered and stretched.
This is a close up of the artefact in the middle of the integrated version.
Any idea how I managed this?
I have just stepped through and the calibration goes fine but its after the registration that the artefact appears.
I just updated to the latest Beta and now its fine! Let's see if I can get this mosaic done now.
Switch off dynamic distortion correction. Likely your data doesn't need it and sometimes, in such a case, the algorithm goes haywire.
