Moon Rise in Pitch Black (This is the Moon NOT the sun AND full Screen is a Must).

Moony Alpenglow I’m thinking. This is a 20 second long time widefield exposure with the camera aperture at low f-numbers (wide open). ISO is less than 1000 for this. High ISO is an evil thing in night time exposures.

I don’t do much work late at night as I do photography all day so there has to be a nap time somewhere. On the occasional night when I’m up over a mile away from my door up on Ridge 1 late at night, I usually bring a tracker along. Set up on Polaris. Takes a few minutes usually. Your camera mounts right to the tracker. 300 -400 bucks on amazon.

Rule of 600 in Star Photography:

The rule states that the maximum length of an exposure with stars that doesn’t result in star streaks is achieved by dividing the effective focal length of the lens into the number 600. A 50mm lens on a full sized sensor camera, therefore would allow 600 / 50 = 12 seconds of exposure before streaks are noticeable. That is unless you are using a device that moves the camera the same rate as the stars move. These “trackers” are a fairly inexpensive gadget but you do have to understand how to find Polaris (North star). Then you can take sharp stars over long intervals instead of getting lines from them moving.

Of course 20 seconds with a wide open iris totally overexposes the moon. That was the point. I wanted to see the moony Alpenglow it was projecting even faintly visible to my naked eyes lolol.

Location Bliss DInosaur Ranch, Wyoming/Montana borderlands (Wyotana).
