Greetings all!

I gave a talk at the Norman Lockyer Observatory on Saturday. I managed to miss the last train, but as a result this meant I was able to use the 10" refractor there to make this drawing of Saturn. There was some chromatic aberration but otherwise the telescope is a good one and a pleasure to use.
Interestingly, the NEB(n) seems to be slightly bluish, so too did the NTB however this may be due to aberration. I suspect this colouring may be due to the CA of the telescope since all my other drawings for the season show these belts as brownish-red. ShRG and ShGR are now quite pronounced as you would expect this far from opposition.

Best wishes,
-Paul

Very beautiful sketch, Paul! You captured a lot of detail for such modest mag so you're a very good observer. And of course a 10" refractor is a hell of an instrument. :D
