Backpacking Astrophotography

Yesterday afternoon I decided to do some simple astrophotography high up in the mountains. I chose the Cavalljoch as the view to the south is unobstructed.

M13 was clearly visible with indirect vision with the unaided eye. Read More

Polarie first test

In preparation for an upcoming trip I am doing some equipment tests to prepare for the opportunity to observe from a dark sky.

It turns out even with the very rough polar alignment that is possible with the built-in peephole of the Polaire tracking mount 30 second exposures are possible with 180mm focal length on an APS-C camera:

3 x 30s – f/4 – ISO 1600, no darks, no flats, stacked with DeepSky Stacker, Nikon AF Nikkor 180mm f/2.8, Nikon D7000
