Greetings all,

Attached is a Saturn drawing made last night. Alas seeing conditions were not too good, although there were a few steady moments. Saturn's is now at B=17.5 and this was detectable compared to the last observation. Other points of interest include:
-Faint EB present
-NEB a most interesting feature- it is hard to be sure but it looked like there might be another component immediately north of the NEBs with a light zone in between. The dark belt then continues and seems to give way to a light (greenish?) NTropZ. There seemed to be a number of dark sublte structures in the NEB(s) and the NEBz, although conditions didn't allow these details to be recorded in any great detail.
-NTB hard to see, greyish colour.
NPR dark.

A-Ring seemed to be a greyish brown, B1-Ring was bright and white in colour, while the B2-Ring was detectable. C-Ring seen at ansae edges.

2335UT: Examined Saturn with my new W#21 filter. Interestingly, the A-Ring seemed to be darker in this filter, while the contrast of the Cassini Division seemed to be somewhat increased. The NEB was harder to make out, but the W#21 does seem to help stabilise the image a little in these conditions.

By 2338UT seeing was too poor to continue.

I don't normally bother with binary stars but I haven't seen Gamma Virginis for a long time, so I decided to observe this lovely binary star

Best wishes,
-Paul

Very nice drawings indeed and observing report, thanks for sharing, but keep on bothering with binaries, please. You will miss endless fascination objects if you don`t!

Beautiful Saturn Rendering. Nice split of Gamma Virginis. That one can be difficult.

Many thanks to you all! I think a nice binary adds to the planetary observation-don't want you all to get bored with planetary work ;-)

I have to say, the image here for gamma virginis is to large and the quality low, it looks much better in my double star log book!!
