EquipmentC11 SCT, On Axis Guider (ONAG), ATIK 460EX main imaging camera, Lodestar X2 guide camera, Losmandy G11 mount, Astrodon 3nm H-a and O-III narrowband filters, blue visible light filter, F/6.3 Reducer, Starlight FeatherTouch fine Micro-Focuser, Orion Nautilus motorized filter wheel
DescriptionThis image of the Crab Nebula shows its blue interior glow that is powered by a central neutron star rotating at 30 revolutions per second. This star generates a magnetic field having field lines about which high energy electrons follow a spiral path line; these spiraling electrons emit synchrotron radiation in the form of high energy photons which produce the blue glow one sees in my image. For this image I captured narrowband data and blue visible light data on Jan 25 and Mar 9 2016 using H-a, O-III and blue visible light filters. To enable autoguiding I connected my main imaging camera and guide camera to an On-Axis Guider (ONAG) which I subsequently attached to my SCT through an F/6.3 Reducer.
