OK, many of you already know, but we are 2 weeks out from the Great Conjunction, when Jupiter and Saturn will appear within a 10 arcminute circle...that's small enough that even cheap planetary cameras on scopes up to 8 or 10 inches will be able to image them at once.
Closest approach is Dec 21, but Dec 20 is pretty good. Dec 22 they've started to move apart, and they're "too far" apart before and after then.
West-Southwest sky, as soon after sunset as possible, the two brightest things in the low sky will get closer and closer over the next 10 days, until they meet on Dec 21.
A 25mm plossl eyepiece on an 8 inch f/10 SCT gives about a 35-40 arcminute circle field of view. So, with an eyepiece you could still go with a 12mm eyepiece for about 160x power and clearly get both planets and the moons. With a ccd, the field of view is 135(A/B) where A is the chip size in mm and B is the scope focal length in inches. The same 8 inch f/10 SCT with a NexImage5 camera (about 5mm chip size) will be too tight at around 9 arseconds, adjust to your equipment accordingly.

Shoot for a field of .25-.4 degrees across.
