42 The Orion Nebula (
NGC 1976 )
This
is the same M42 as the one below, but with the addition of a close up of
six of the Trapezium stars at the heart of the nebula. M42
& the often forgotten M43 De Mairan Nebula in Orion. This was my first
attempt at dithering between exposures, and first go with new capture
software. The dithering seems to have spread the hot pixels around, but
the stacking software had reset its "Hot Pixel Removal" options,
so they weren't removed in stacking. Instead I tried to remove them in
processing. The Moon was out too of course which didn't help, but the
night was more for testing than imaging. This image was taken with the new Canon 1100D. 30 minutes of 90 second exposures for the main image, then 10 x 30 seconds & 30 x 10 seconds for the core, all ISO 800.
This image was taken across a period of 45 minutes,
finishing at 4:30am on the morning of September 8th, 2013. Unguided, unknown exposure Unguided, approximately 20 minutes exposure in 90 second subs. |
