WAITING FOR THE SHADOW      ASTROPHOTOGRAPHY by Joseph Cali

Astrrophotography from a fixed tripod

All the images on this page have been taken with a DSLR with high ISO, short exposures on a fixed tripod.
No tracking or guiding of the image.  In 2013, I derived a formula to work out the maximum time for a camera
& lens combination

Pentax 12-24mm f4 / 15mm f4  Pentax K1  ISO 25600   10s

Pentax k5 ISO6400 3s exposure Pentax 10mm f3.5 full frame fisheye ED lens
