Image Border

[Tangoringo]

Good evening folks.

Just a very quick question. I'm using a QHY 10 with APT for image capture with all settings entered from the QHY website.

When I open my image files I'm getting a border on all files ( including flats,darks and bias ) Any ideas why this border is here, and if there is no obvious fix, can I leave it in situ until images have been stacked and then crop when all the stacking and processing is complete or will this have a negative effect on the pre process?

Please find attached an example un-debayered single sub taken last night ( saved as a tif ) with the offending border.

Any thoughts at all?

Thanks in advance,

Ian
