RGB imaging with my dob and DMK21AF04

Well last night was my first light with the full RGB setup.

I've got the Atik manual filter wheel, got a Mogg C-TF adapter so the DMK21AF04 could screw onto the front of the filter wheel, got a set of 4 baader filters (IR/R/G/B) from MyAstroShop and I'm ready to go!

Everything went pretty smoothly for a first night out, apart from the seeing. The conditions were terrible and so I used the conditions as a practise run, and see how much wobbling I get when I manually roll the filter wheel.

I was actually pleasantly surprised. I was quite worried how much time i'd lose changing filters in a short capture window for Jupiter. I really only lost 4-6 seconds when changing filters and waiting for the dampening to die down. I was expecting about 10 seconds so I was happy.

The planet wobbled itself back into the same spot in the FOV, so everything was good. On a night of better seeing i'll be ready!

Here's a picture showing it setup.
