Thanks again.

Marc I saw your image on the visual forum and it still separates out obviously at 2.4m - would have thought 6m at least. We have the advantage in Au of overhead viewing. Back in the UK it dances on the rooftops scintillating severely.

Mike and Trish I image planets with my 350mm newtonian and Flea3, so after collimating on the star Sirius and turned the gain down on my Flea3.

Red,Green-3000frames 16fps
Blue-4000frames 16fps
Luminance-2000 frames 22fps.

I sharpened with Registax5 wavelets and used the histogram for more stretching and stacked RGB with MaximDL and finished in PShop. Simple quick processing really.

I imaged it back in 2011 with a Mintron and the RGB gave a pleasing slight blue colour.

Regards, John.
