I was really excited when I heard that OM System had produced an Astro version of its OM-3 camera. Mirrorless and DSLR cameras modified for astrophotography have been released regularly by Canon, Fujifilm, Nikon and Olympus in the past ten years. But few of them stay on sale for long. Released as special editions, they disappear almost as soon as they appear - a bit like a twinkling star!
The OM System OM-3 Astro has particular interest as the OM-3 already has a few features that make it an appealing option for astrophotography, such as its Starry Star AF system. But the appeal of the special addition is the modified sensor that is optimized to see the red Hydrogen Alpha (Hα) part of the spectrum, which is crucial for the best photos of nebulae and dying stars.
