Description

This is a reprocess of my earlier M42 image taken from Bartlett Lake in AZ. The diffraction spikes are from stopping the lens down to f/7.1.

This image shows the true power of imaging at a dark sky site. Taken with a portable tracker and a stock DSLR, it handily shows more detail in the reflection nebula than the image I took from my Bortle 6 backyard with a light pollution filter - a 1.3 hour integration using a camera lens at f/7.1 outperforms a 3.4 hour integration using a cooled monochrome camera with filter wheel and an 80mm f/6 triplet! Dark skies are amazing!!
