A very nice composite image. Lots of detail!

Not too bad Julian.

Can I ask you why you are using Drizzle ?

[Telrad]

Really lovely shot Julian, I like the definition and colour. GRS and a barge look visible. Well done!

Nice work, despite poor seeing.

Very good image, I like it!

Thank you all very much for the kind comments.

...Can I ask you why you are using Drizzle ?

Good question Clayton I'm not sure whether I'm fooling myself on this but I reasoned that I'm probably undersampled with my setup and that I could improve the image by using drizzle stacking. This is what I'd been reading:

Of course, the main effect is probably just to double the size of the image, but I find it slightly more intellectually satisfying to do it by drizzling than upsampling in Photoshop.

I'd be interested to know yours (and any others') thoughts.

Very effective and good results Julian.
