Hi All,

First post here. Great forum! I have gleaned as much as I could absorb in one go and produced my very first sketch, attached. Please feel free to contribute any comments or criticisms that you feel might help me improve my technique.

This sketch was made on Oct 03, 2010 from my light polluted (red zone) suburban backyard. Seeing and transparency were both poor, each rated 2/5. I use a Tele Vue 102 on an alt/az mount, with a 7mm Nagler Type 6 EP (mag 126x, true FOV of 0.63 degrees). The sketch does not quite depict the full FOV, as the scope was unguided.

The ring structure was easy with averted vision, and I also noted a possible brightening of the ring on the southern side. I am not sure if this is readily apparent in the sketch, but it was subtle at best. A UHC filter did not improve the view, neither did higher magnifications.

The sketch is graphite pencil on white paper, inverted and processed using GIMP.

Regards,

Ian

Welcome on CN! Your sketch looks very good! I wouldn't say it is your first one (my first sketch was horrible!). Hope to see more of your hand.

Mentor,

Welcome to the Cloudy Nights Sketching Forum. Your observation of the Ring Nebula (M57) is excellent. You have captured this ghostly ring very nicely. We look forward to your future observations on the forum.

Carlos

Thanks for all of the encouraging comments! I left lots of room for improvement (I think the outer edge of the nebula should be more sharply defined, the ring is scaled slightly too large compared to the star field, the scan resolution is too low, etc., etc). Things to focus on in sketch #2....

I was out tonight trying for M56, but it was terribly faint under the poor transparency conditions. I eventually lost it completely only to look up to see that a high thin cloud bank had rolled in. Next time....

Great work on your first sketch, Ian. You've given a convincing soft, subtle treatment to it that's not always easy to do.
