M42 - Orion nebula
My second attempt at processing this image achieved more detailed nebulosity than the first image posted earlier. Some 1270 light-years distant and 24 light-years wide. Imaged from my back yard in Cranebrook, a fringe Sydney suburb. Celestron GPS11 in altazimuth mode, Hyperstar f1.8 lens, Meade DSI III camera. 40 x 15 seconds (8 minutes) total exposures.
