Old processed photos
I've worked on some urban deepsky photos last year late Novemeber. Haven't touched them much since acquisition, here are the results.
Each image involves 1 hour of exposure, 60 subframes of 1 min. Sky90, Modded 40D, EM11 unguided.
The background is not even, i don't really understand why even after PixInsight manual correction and IRIS auto correction the unevenness is still very prominent. THe are different patches all round the place which hinders post-processing of weak signals. May be it was because I haven't applied a correct flatfield...
