I noticed that there was a possible overlap between the two data sets, for the aforementioned objects, for a mosaic. As that is so I thought I would give it a go, although admittedly I did find it hard to do. There was also an odd issue after I used Starnet++, which I try not to use anyway, which meant I had to clone a lot of errors out that it had caused, which are noticeable up close! (I have never known it make errors like that before). Anyway I think it was worth trying to process this, and hopefully posting. Thanks everyone. Have a good day!
Pier 5 uses a Takahashi Epsilon 180 F/2,8 astrograph, on a Skywatcher EQ 8 mount with a ZWO ASI071 Pro Colour CMOS camera, and I used 170 subs of NGC 7000 and 170 subs of IC5906, all at 1 minute long each! The integration time was thus 5 hours and 40 minutes.
