Description

Sharpless 2-240 (the Spaghetti Nebula) is a supernova remnant (SNR) in the Milky Way, straddling the border between the constellations Auriga and Taurus. It was discovered in 1952. It is estimated to be around 3,000 light years from earth and has an age of around 40,000 years.

This nebula is huge. It probably would have taken a mosaic of 9 to 12 panels to capture the whole thing. It's captured using narrowband filters. I put Ha in the Red Channel and OIII in the Green and Blue Channels.

All of the data was captured in October and November, 2019.

Optolong Ha: 159x240" (gain: 139, offset: 21)
Optolong OIII: 130x240" (gain: 75, offset: 15)

Integration: 19.27 hours
