13. Messier 42, Orion Nebula |
| Distance: 1344 ly |
| App. Magnitude: 4 |
| App. Dimensions: 65'x60' (cf. telescope field of view 119') |
Notes: The Orion Nebula is 24 ly across and relatively close, so it shows up large. This is our first image with the camera modified to allow the red Hydrogen-α light energy band to pass. The green hue in the interior may be reflected light given off by ionized Oxygen produced in star formation. Zoom in/out with ⌘↑(+/-) (Mac), ctrl (+/-) (PC). |
