Everything here is manual. If you care to look, I started with Jupiter with glow in the sky near sunset (upper left) then you can go clockwise around the paper through the M11 sketches. I recently did a similar exercise with M4 at high power; everything here is low power since that is what we will be doing. There is a very real possibility we may be restricted to daytime, so we have been mentally registering the southern skies near sunset and the moon positions/appearance during day time hours. It all makes for a very interesting problem set. Not shown but also worked is the refractor with astro-video on a 5 inch TV screen....so 8 or 10 can huddle around during sessions that concentrate on sketching...so we can do it together. It worked....solar cells to charge the battery by day...battery runs the camera and monitor at night or day time. Our host has a projector with a video input so we may be able to hook the camera to the scope, project the moon or a nice bright object, and do a chalk talk with translation to the little village. We shall see!!

I hope you bring some of your naked eye lunar and other sketches with you on the trip. They may prove to be instructive.

I would not worry about the low power approach. Chances are that the skies are very dark and very suitable for low power instruments. -------------------- Rony My Astronomy Sketches My Binocular Sketches Post Extras:       WadeVC Carpal Tunnel Reged: 12/02/05 Posts: 2778 Loc: Lodi, California, Re: Low Power Practice on M11 and Jupiter [Re: rodelaet]       #2657665 - 09/22/08 11:45 PM Edit   Reply   Quote Quick Reply   Roland, The Wild Duck Cluster is one of my favorite OC's, and you managed a very good sketch using binos. Naturally the "King of the Planets" is equally awesome. Nice. -------------------- Orion XTi10 f/4.7 Orion XTi8 f/5.9 Meade NGC 70mm f/10 Orion UltraView 10x50 Wide-Angle Binoculars My Sketch Gallery My Astronomy Blog A wise man can see more from the bottom of a well than a fool can from a mountain top.
