Hi all
Heres the deepest yet image ive taken of this comet, taken earlier tonight. I discovered that Iris software has a surefire way of aligning images of a moving comet. instructions
here
The more i use Iris the more I love it, and amazingly it is freeware.
Image is 17x2 mins ISO800. I could do no longer subs as comet would trail, its scooting along.
Hutech LPS filter, Baader MPCC, Meade 6 inch f3.6 SN, Hutech modded 350D, each sub guided on stars and aligned, stacked using the above method in Iris, finished off in Photoshop. sattelite went through the last sub.
