Niv, 151 x 1 minute subs at ISO1600. The bigger the scope the better the chance of detecting a tail. None seen in my 4 inch refractor but people have seen it in larger scopes.
... how is it you get consistent cloud free nights?!
Believe me Simon it isn't normal. Though Winter / Spring in northern Australia typically has less cloud than Summer, which is usually a total write off.
Great pic Kevin I saw it this morning but it was so windy I just took a snapshot with the Gstar .
Thanks Derek!

H, The comet moved quite a bit in the 3 hours over the exposure, so two methods of stacking were used, comet stacking for one, star stacking for the other. The two stacks are then combined in photoshop. DSS does similar in comet+star stacking but makes a mess of it.
The main difficulty in combining the two stacks is residual streaking left over from star trails in the star stack. A median combine in stacking helps reduce them. In Photoshop, instead of "normal", use Lighter colour" in the layer combine. Any streaks left over are touched up by hand. To do it seamlessly can take some time and gives me a headache lol.
Ripper imaging & processing Kevin
I was just running some Co-ords and found it meeting the Pleiades in Oct
Should be as interesting a capture, I actually have a request to do the Pleiades this season, would be a nice addition to the composition.
mmmm, well thats kinda strange ? Ok, thanks for your feedback Kevin, I was pretty confident the Orbital elements went in stellarium ok, so, not sure what gives there ? I run it again some time soon
All the best ...
