Just out of interest, are you using focus stacking?"Another Hoodoo Sunset"

Looks impressive. How long did it take you to expose this frame?"Star Gate" - Southern Utah
The 500 Rule for avoiding star trail says your full frame equivalent focal length would be 500÷(3×60) = 2.78mm. So what focal length was actually used?Thanks, this was approx 3min exposure.
I use a star tracker which allows me to shoot up to a 5 minute exposure with no star trails.The 500 Rule for avoiding star trail says your full frame equivalent focal length would be 500÷(3×60) = 2.78mm. So what focal length was actually used?
Wouldn't that blur out the foreground though? Or are the foreground and stars separate takes that are merged?I use a star tracker which allows me to shoot up to a 5 minute exposure with no star trails.
So you set up the tripod, take one photo for 3 minutes (sky), and then without moving the camera, you take a 2nd shot ('more normal evening shot') of the tree and landscape? Then you go home and merge one onto the other? How do you this...do you literally have to digitally cut out the tree and paste it onto the backdrop of the long-exposure night sky?Yes, you are correct.
To get a balanced overall exposure, the foreground and sky are 2 different exposures that are merged together.
Thanks,
