Originally posted by PENFRED Hey, thanks all for the responses; this is more complicated than I thought.
jbinpg - If I do precise calibration successfully in the astro on/off menu, I shouldn't also need to do calibration (gps/compass menu) as well, should I?
int obs - Didn't realize I needed to be in bulb mode for astro to work; that may be my whole problem right there. However, on the K1, I don't see the "start" menu item you refer to. The menu (camera #3) allows you to turn astro on/off and do a precise calibration, then in bulb mode, you can use the green button to either set the timer for automatic off, or just use bulb and hit the shutter button twice for on/off.
Please explain.
Thanks much for the help.

Hi Fred - I just got home from work and saw your post. A few things - Yes, it needs to be in Bulb since the shutter time can be any value up to 5 minutes or 300 seconds. If it's in any other mode, 30 seconds is the longest exposure that the body will allow. While it is in both GPS and Bulb, the body will time the exposure to the duration you specify in the GPS pages.
I don't have a K1, so I went and looked at the K1 manual. They have changed the interface considerably, actually it appears to be a bit simpler but different. It appears that they have removed the "start" from the menu selection. It appears that if you are in both GPS/Astro and Bulb, then by pushing the shutter, you are doing astro tracking.
In terms of the next dark night - it's here, tonight and through mid next week. The moon rises at midnight tonight and moves later each day. The Milky Way rises in the East South East a bit after sundown, with the new moon on July 4.
