Nice shots all over.
Cheers, Duncan

Thanks Duncan, Mars is moving away but should still be a reasonable imaging target for a while yet.

Nice work, on both Trevor. The other bonus with winter is more dark hours

Thanks Clayton, yes, looking forward to be out imaging by 7 pm or so.

At the moment I'm experimenting with capture timings of 120/90/90 for saturn (RGB), this seems to give a good result. The smaller size of saturns disk as seen from earth means that there is about 2x the time for capture compared to Jupiter before you get an equivalent amount of blur.

cheers, Bird

Thanks Bird, that is an interesting timing routine for RGB. I have been using 60/60/60. Considering how dominant the B channel tends to be, the extra capture time for the R channel seems worth a try.

It certainly hasn't had any sort of detrimental effect on the look of your latest images, which are outstanding.

At the moment, for Saturn, I am using my 30mm extension with the 3 x Nagler Barlow but I am thinking about doing away with the extension for a brighter live image and fuller histo , especially for the B channel.

Over the next week or so I intend doing some intensive work on Saturn, weather permitting, to try and compensate for the overall drop off in luminosity due to the rings being so far closed. I'll give your idea of extending the capture time a go. Even factoring in the time it takes to rotate a manual filter wheel I should be able to extend my time a bit.

Thanks Troy, onward and upward. It's pretty much well a continuous learning experience.
