Very nice image Jake with good detailing in the rings as well as in the cloud tops - excellent!

Very nice! I guess you are using 4x barlow to get to F20. Are you using a barlow? I have the 200p and the same camera (colour only version) and managed an image close yours from last Saturday, I used a 3x barlow and so was only F15. I'm wondering whether to get a nice new powemate to get to F20 or F25. Just concerned it's too much..

Thanks Richard - hopefully not the last go this year, though the weather is not helping at the moment

Andy,

I'm using my filter wheel, the Baader x2.25 zoom barlow + some 120mm of extension on this to get the 4000mm focal length.   Even then the QHY camera is just inserted enough to grip.    I had to get a low profile M57-2" adaptor to replace the standard SW extension tube to allow sufficient space for the filter wheel, though with colour you won't need this and should be fine.  

I was using a Revelation x5 ED barlow, which dependent on how far the camera was inserted, gave me x3.7-x5.   However, this barlow was giving some very odd reflections/aberrations so it's been retired until I can source a x4 Powermate.

Thanks snakeyJ, that's great info, I should try extensions tubes next time. I'm also considering the powermate 4x as I have seen from other members it's rather good with a 200p. Pricey but worth it I hear. Might sell a few bits first. Heh!
