Great thread, Suzy!

Thought I'd add my two sketches from tonight's close encounter done from my home in Sydney.

The first is of Lemmon using my 8" dob and my 10mm XW giving 80X. I could make out its tail a lot easier than my first viewing of it close to two weeks ago.

The second sketch is a wide field sketch using my 80mm f/5 refractor at 11X with a 36mm Aspheric Hyperion. The field of view here is a tick over the 6 degrees this scope/EP combo gives. Here I've not only managed to fit Lemmon and 47Tuc, but also the smaller globular NGC 362. The SMC alas is overwhelmed by the light pollution of Sydney to be seen. YET, I was still able to catch a glimpse of Lemmon's tail! This really surprised me, but it shows the advantage of a small aperture can have in a light polluted enviroment where the back ground sky glow isn't as intense. I couldn't see the tail in the 8" using low power because of the background sky glow.

I'll do a more detailed write up of the sketches in the Obs Forum sketching sticky.

Mental.
