M42 another effort but not in RAW

[rodrigol]

Somehow I managed to change the quality setting on my D7200 from RAW to jpeg normal and took 50+ shots of Orion. Skies were clear and I decided to try out a new optolong UHC clip-in filter. Biggest surprise was that our council decided to turn off the street lightning at 9pm - so, I perhaps did not need the optolong filter! I stacked and integrated on PI and ended processing a little in PS. The background is dreadful but I was surprised I did manage to capture so much data and keep knocking myself about the image quality setting....Here is the result of this mishap:

I'm curious as to where that rectangular outline has come from..... ??  Have you recalibrated the size of some images...... Is it a weird internal reflection of the sensor ??

I think this is the optolong that has come loose! I fixed this issue by bending the little tabs in the lower part of the filter so as to make sure filter clips in place.
