LX100 Pickering Lane morning stars 005.JPG

LX100, iA mode, pops off six shots in rapid succession and automatically stacks them. -4.3 degrees F. SOOC.

Cheers, Jock
 
Oh yes, I see hundreds of stars now. It’s nighttime, and when I turn off the room lights, after cleaning my screen, — there they are! And so are the trees and power lines. I wonder how this would compare to a 20 or 40 sec. exposure?

Les,

I've done a little research about this, and a 20-40 second exposure would result in the stars beginning to appear as streaks, not dots, in the frame.

This post -- LX100 night shots -- shows the difference between the "stacking" mode on the LX100 and a 10-second time exposure. As nearly as I can figure, 13 seconds is right at the ragged edge of when the stars start to streak with a 24mm (e) lens.

For lots of very useful information about photographing the night sky, I recommend Lonely Speck

Here's a link to his quick guide to astrophotography: www.lonelyspeck.com/nightscapes-guide Very useful!

Cheers, Jock
 
Thanks for the Lonely Speck site information, Jock. I don’t have many chances to try astrophotography, living in suburbia with a limited sky view (but beautiful trees). I’m inspired though, so I might give it a try next night when a) there are no clouds, b) the temperature is above 0℃, c) the winds are not too high, and d) I’m awake. A total power blackout would be helpful, but not desirable. Or, perhaps, early morning with similar conditions.
