Just doing a quick bump.
This photo is junk (I wasn't setting out to snap this, I was just out testing something - my O-GPS1 and my camera both were running out of juice when I walked out so I didn't have much time to play.
When I have a night free I intend to go back out again and see if I can figure out some better settings.
Considering (not counting the camera and astrotracker) it was done with $40 worth of equipment, I'll call it a win.
Auto Sears 300mm, stopped down to f/8 using a cheap Vivitar 3X-22 teleconverter, When I have time to actually seriously play at this, I'll see if I can stop the camera down enough to not have Jupiter blown out.
But seriously - I CAUGHT THE MOONS! Badly, but I caught them!
I think my plan of attack next time will be to simply stop down ever harder on the lens, or try the shot minus the GPS unit so I can get under 10 seconds as an exposure. If I'm blowing highlights (On Jupiter!) then I can simply keep lowering the exposure until I find the sweet spot for the planet.
