I've been itching to have another go at this comet and was encouraged by the opportunity to catch it travelling by m10 (thanks for the heads-up Glen). Last attempt was with the c14 @ 2700mm, this time I put the Hyperstar on for some shots at 740mm (much better for the starfields).
It's been about 6mths since using the Hyperstar - I was super rusty and absolutely everything was out of alignment. Unfortunately by the time I had it ready to go the nearly-full moon was beaming down on me -aint no flats that will fix full-moon reflections off a big bright red asi2600mc sitting infront of the corrector plate!!
APP doesn't have a function for stacking the comet and starfield separately, but after a bit of trial and error I found that 4x60sec subs still give a decent view without too much elongation to the core of the comet (to my eye this was nicer looking than the alternative of star trails).
My spacing / tilt was pretty rushed and definitely not right so I did a heavily cropped version that was a bit cleaner. Still i'm really glad to have managed the capture!
Thanks for dropping by!
