Attached is a Saturn drawing made last night. Seeing was variable but there were a few steady moments. NEB broad,the NEB(s) component was the strongest. It was hard to pull out the details with complete certainty as the planet continues to present smooth almost continuous features. NTropZ seemed to have a greenish cast,NTB broad light brownish in colour. Bluish colour present at the NPR.
For the first time this apparition I was able to make out the B2-Ring which was greyish in colour. B1-Ring white in colour while the A-Ring was greyish. C-Ring quite bright at ansae edges.
Please find attached two drawings of Saturn made on 06-07 May 2013. The skies were quite hazy and seeing was never better than AIV, still there were some interesting features on the disk. It seemed as though there were two dark patches in the NEB(s) which may have extended into the NEBz. They were better seen with a W#80A filter but then the sky continued to get hazier and the image fainter. By the time of drawing 2 they had appeared to have moved with the planet's rotation.
A-Ring appeared to be slightly brownish, B1-Ring bright and white in colour, B2-Ring seen, though not easily. C-Ring still seems to be fairly prominent at ansae edges.

A wonderfully pleasant night and very good seeing was in prospect from the start I felt ? trusting to instinct ? and was not disappointed! I was struck by the very dark rim of the NPC particularly where it looked quite flat and rather feel I got at least an impression of the hexagon-effect; the steadying conditions allowing fair scrutiny here. Also was quite convinced that the following Ring A was a fair bit darker than in the preceding ansa with Encke (IAU & ‘classical’) readily apparent; but uncertain on the p. ansa.
With the seeing becoming at it’s best Enceladus,then Mimas,jumped into view (no need hiding Saturn!) demonstrating the importance of steadiness as well as good transparency for getting fainter moons in the planet’s glare. Enceladus still well held when the apodizer was attached ? Mimas very doubtfully!

Some steady seeing on the night of May 6th allowed for my first decent capture of Saturn for the current apparition. With a culmination altitude of 27 degrees, it's something of a challenge to catch the planet between obstacles for me at present.
