A quick session tonight getting my telescope back up and running after the frigid weather this winter caused some issues with the cabling. Now I have move all of the cables onto the telelescope itself, including the Raspberri Pi 4 computer that runs the telescope, so all cables are static and only the power cable to the computer, usb hub, cameras, and focuser motor runs from the mount. Control of the mount is now via a Bluetooth based controller and network is wireless so I’ve eliminiated pretty much all of the cables I can! Only 10x60s exposures, no calibration so I’m hoping the weather stays decent so I can collect some more photons on this object!
The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion’s Belt in the constellation of Orion.[b] It is one of the brightest nebulae and is visible to the naked eye in the night sky with apparent magnitude 4.0. It is 1,344 ± 20 light-years (412.1 ± 6.1 pc) away and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light-years across (so its apparent size from Earth is approximately 1 degree). It has a mass of about 2,000 times that of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula.
