This is a monochrome picture of Orion constellation captured by Piotr Maliński.

Details from his mail:

Last weekend I've made a test image of Orion and Rosetta nebula using DMK21 and 8mm f/2 industry CS lens with Astronomik H-alpha filter on top of it. The Orion part is 144 frames at 32 sec. Rosetta is 90 frames at 32 sec. Both with darks and at about 80% gain. All the H-alpha nebulosity is visible (barnard's loop, horse head, flame, m42 and other. The small lens gives around 145 arcsec/pixel scale.

Thank you Piotr!
