Hi,

Last night I made a couple of sketches under very good seeing conditions.

Attached is a pencil sketch of Saturn. Recently Saturn has presented very subtle details on its globe. I gave it a whirl by making this sketch after observing it for a very long time.

Other details are embedded in the sketch.

Best,

Sol,

Beautiful. Love the capture of the bands and the contrast you nailed with them, very subtle, very life like as always. Thank you for sharing your observation with us.

Hi Sol,

A very beautiful and impressive sketch of Saturn as it now appears in the night sky. You are seeing a fine amount of detail and are capturing it as most cannot. Well done. :bow:

Frank :)

I find it very difficult to see anything on Saturn. So I'm very impressed by your sketch and all the details you saw in the belts.
What magnification did you use?

Thanks to everyone for the compliments.

The eyepiece & Barlow combination yields 400x magnification.

Mars showed albedo features well with a Wratten 21 despite its smaller size. I simply had too many interuptions from folks stopping by to take a look to get a fully finished sketch.

Thanks again.

Sol,

A beautiful observation of Saturn with nearly edge-on rings. You have recorded the subtle bands over the globe as well. Thank you for sharing it with us all.

I look forward to your future observations.

Carlos

Another beautiful sketch by you :bow: :bow: :bow: You have really brought out the subtleties in the planets cloud features; an excellent observation and rendering.

May we borrow your image as a current template?

I was wanting to check a site that predicts the appearance of Saturn's rings as I cannot remember now, if they will actually become more edge-on yet this season.

Thanks for posting this; it's good to see you back to the Sketch Forum again.

Thanks very much Mark.

Here is the template I made for the sketch. All are invited to print it out and use as you wish. Please note that the template is shown with north as up. The tip off is within the ring thicknesses adjacent to the globe. The slightly thicker ring crosses the globe, the thinner one has the globe in front of it. I know its a very small difference, but I thought I'd point that out.

Other than making your own templates, Everlastingsky uploaded a degree by degree ring tilt series of Saturn templates that amongst the best I've seen. He/she posted here and there might be link in the "best of" section here.

Best,

Superb sketch as usual from you, Sol.
I was lucky to have one night with excellent seeing last week and Saturn in my 107mm at 175x looked much like you sketched it. I was particularly thrilled to detect the Cassini division as a "dip" in the brightness of the rings about 1/5th from the tips, just like in your drawing.
