Description

Well after a mammoth weather session, I finally managed to image this iconic object. Sadly, I have some minor field rotation on this, yet on a previous attempt before the weather closed in, and with a worse polar alignment on that occasion too, I had zero rotation! I cannot fathom that out. Anyway, this was 72 subs at 4 minutes long each, totalling 4 hours and 48 minutes, using the new 130 triplet. Alnitak was an issue as normal, as I am not good with bright stars. Thanks everyone and I hope you are ok...
