]Hi middy - pretty image of Corona Borealis - beautiful
heres my snp screen shot of the time you imaged - you indeed have the right spot - not sure if my orbital elements are exactly correct (may be out by 4 arc seconds or so) due to snp harvards single OE available (and its for the original SW3 before breakup LOL) I had to modify some of the ones available on the net - PITA! - had to do my own julian dates for perihelion, so not sure if thats the problem - anyway should be close enough.
There does seem to be a similar streak in the tree's near it - so cant say for sure anychance of stacking more for a deeper shot? i did stretch the hell out of it PS and there seems to be something there?
PS have included the obit path (blue line) for that moment in time - interesting to look at the other fragments on it - some slightly off the path
yep clouds/rain for us to hOughy
hope it clears for ya mate (re Berts sexy lens!)
PS EDIT: middy, re comet from 90's sure your not thinking of Hale Bopp
