I finally had views that exceeded 6 Pickering. I was out with my 70mm achro as its rising earlier and earlier and I set up around 10 so, I did the quick 30 minute observation before it sank appreciably.

Cassinis: this isn't the best this scope has seen it but its the best view this year. Typically it forms a gradient or soft blend that joins the contrasting a and b rings, tonight it was better defined as reflected in the sketch. Nicer nights have it nicely etched.

Globe: not a hint of the Hex spot . Just a uniform grey all the way through save for the EZ. In the past Ive seen a temperate zone but it'd been a while since the .hlobe has presented one bold enough for my 2.7" refractor. Indeed, in 6/10 seeing its quite subtle d en with the 8".
A clean sterile globe.

The Crepe Ring where it crosses the globe was easier than Ring As shadow but both were quite delicate. The dual shadows only showed in the best moments. The shadow of the globe on the rings was far more robust.

Color was a very very subdued cream grey that was virtually colorless.
Best views were at 133x with a 9mm abbé and 2.5x Barlow. Going higher to 162x wasn't bad at all - but it didn't bring anything new to the table.
Didn't bother with filters. It needs more aperture for that.

The nicest view in a while. Not stellar but not bad. Danced around frequently in the seeing.

Pete,

That is better than my view with a slightly larger reflector so far this year. Saturn really needs steady skies or a very long time waiting for a brief glimpse.
You really did capture great detail with 70mm.

Frank :)

Thanks Frank. I drew Cassinis a little sharper than I should have. That's more indicative of 8/10 seeing. Its extent is the same but it was a little softer edged. Ill see if I can't drag out the 8" tonight weather willing.

Nice sketch of Saturn with a modest aperture , good rendition of the shadow of the globe on the rings.

There was no darkening toward the extreme polar areas that night, I suppose. Hey! Why not your 8"? I'll bet that'll get some more detail! A nice sketch: smooth shading technique, everything proportionally as they should be according to my memory of views of Saturn recently. To my eyes, though, the planetary shadow on the ring is usually darker, but that could just be me.

Nice work Pete,

I always like to see what can be seen in a small scope. Folks are often amazed what a 70mm refractor can do.

Thanks guys. Ed there wasn't a prayer of polar darkening that night through that scope. Not that it hasn't shown at other apparitions - and a temperate zone too. The shadow of the globe on the rings is representative of what I saw though the crepe band and ring shadow on globe are a little understated. Ehhh - it was a 30 minute observation afterall :).

Hi Pete. Enjoyed your report. Nice work. What is the Hex spot and the Crepe ring?

I frequently learn something reading these kinds of reports and looking at others' observations.

Well done Pete! In spite of the modest aperture you brought out a lot of detail.

Nice sketch. Amazing what can be seen with small scopes. I use a 70mm f7 achro as a finder but will have to put in an XW 7 or 5 and see what that looks like, only problem is the plastic focuser...it's a bit nasty.

Thanks guys. That was an enjoyable observation. The views through the 70mm while a but simple compared to my 8" still are very attractive to me for the clean look a 130x Saturn can have with a nice refractor. I'm glad others feel the aperture can provide good views too.

Nice sketch Pete, you picked up a lot of detail in your sketch.

Best,
