Orion nebula II

Test shot: Pentax Astrotracer mode 3.

 

A cropped image of Orion's Great Nebula. 40 seconds @ f5.6 ISO 1600 in quite ordinary atmospheric seeing, using an HD PENTAX-D FA 150-450mm f4.5-5.6 lens on K1. Some tweaking of levels and a quick pass through Topaz Denoise AI. The star shapes are pleasingly undistorted.

 

Please note this is one of two test shots for use with Pentax Forums' Astro group. Feel free to comment here, but no worries if you don't.
