Hello, I've been experimenting with extension tubes to see if I can get a larger image without compromising on the quality.

To be honest whilst the image size is ok, the other night the seeing didn't seem too fair so I'm a bit dissapointed, particularly seeing as I got some storm detail in a smaller image the other night.

Still, can make out the Cassini division - just, and the shadow of the planet on the Rings plus the main band around the equator. Can also make out the darker C ring.

Anyway, thought I'd post one of the images. 1000/3000 stacked in Registax and tweaked in Photoshop.

The extension tubes do provide a larger image though i need to take some more shots to see if was just the seeing, my legendary focussing or whether the tubes simply enlarge the image at a cost of the image quality.

Comments welcome as always.

Thanks for looking.

Thats quite a good image , did you use a diagonal in place aswell as the barlow and extensions ? i ask because i use a skymax 127 mak 2x barlow + extension but i also use the diagonal and my image scale seems larger than yours but really you should have the bigger image scale due the the longer focal length , just a thought ? check my album out to see what image scale i get . Again great attempt though conditions have been bad for a while now at least in the UK and the planet is slowley moving away so well done

Tx BigAl. Ill try the diagonal next time and see what happens. Thanks for the kind comments

Not too bad. Hard to get anything good if the seeing is not so good.
