Description

Imaging the Great Orion Nebula (M42) with an ED80

For most, the Orion Nebula is one of the first deep sky objects that people getting into astrophotography take since it is pretty and it is easy to spot. You don't even have to take a very long exposure to get a decent looking image. My first deep sky image was a 25 second exposure of M42 taken last year (1/1/15). I was happy with the image but I also have learned a lot since taking that shot last year and so revisited the Orion Nebula from my driveway the other night. My regular astronomy meeting with the Boothe Memorial Astronomical Society (BMAS) was cancelled because the town (Stratford) never plowed the road/parking lot to our meeting area and so, I took the following image from my driveway on 2/5/16.

Exposure: 7-300s, 10-60s, 10-10s, 1-10s (total exposure, 46min 50s)

ISO: 800
