Simeis 147 6-panel Mosaic

54 hours of full-color OSC data, using a fast 14" rasa-style platform at f/1.8 This is a SIX panel mosaic, very large. Couple it with the four panel HaOiiiSii data from T-29 (coming soon) for an amazing image!

Simeis 147, also known as the Spaghetti Nebula, SNR G180.0-01.7 or Sharpless 2-240, is a supernova remnant in the Milky Way, straddling the border between the constellations Auriga and Taurus. It was discovered in 1952 at the Crimean Astrophysical Observatory by Grigory Shajn and his team using a Schmidt camera and a narrowband filter close to the Hydrogen Alpha transmission line. It is difficult to observe due to its extremely low surface brightness. This discovery was part of a survey conducted between 1945 and 1955, most likely using captured German equipment, as the observatory was practically destroyed during WWII. The Schmidt camera had a field of view of 175'. Many previously unknown hydrogen nebula were discovered this way, as they are not readily visible in regular photographs. The nebulous area has an almost spherical shell and a filamentary structure
