|The famous "Orion Nebula" (also known as Messier 42 & Messier 43) in the constellation of Orion on
February 25 / 26, 2014. The diffuse nebula (Messier 42 in the lower part of the image, Messier 43 in the upper part) is a region of star
formation. It is 1344 light years from Earth and measures 24 light years across. It is visible to the naked eye.
Fifteen exposures of approximately 3 minutes, 10 exposures of approximately 60 seconds and 8 exposures of approximately 15 seconds, all at ISO 400, were added separately with the DeepSkyStacker software and then the three resulting files were added in Photoshop (theoretically resulting in a 63 minute exposure, but due to the masking work the effective exposure time is shorter).
|Equipment: Canon EOS 450Da camera, TeleVue ParaCorr Type II coma corrector, 16" f/4.5 dobsonian telescope "Ninja" riding on a dual-axis Tom Osypowski equatorial platform, Lacerta MGEN autoguider, Lacerta off axis system (field of view comparison: image of the moon with the same equipment).|
