Order Notes

The very bright star, Deneb, which is the tail of the swan in the constellation Cygnus, is just outside the field of view in this image. Unlike most of my astro-photos, this was captured not with a telescope, but with a camera lens of just 200mm focal length (less than 1/3rd the focal length of my AT111EDT telescope). That means that the area shown is 3 times as wide as in most other images here. NGC7000 is about 1,600 light years from Earth. The Pelican Nebula is just above the N.A. Nebula.

The image was captured at Wa-chur-ed Observatory in July of 2011 as a test of the lens for astro-photography. It performed quite well, although testing indicates that it is somewhat sharper at shorter focal lengths.

Scope: Tamron 70-200mm f/2.8 zoom lens (at 200mm, f/4)
Mount: Orion Atlas/EQMOD
Camera: QSI 583 at –15C
Exposure: 10 x 480s H-a, 10 x 480s O-3 (2 hrs 40 mins total)


About Greg Marshall

I am a retired electronics engineer and after a few months of enjoying my leisure I began to miss doing product development. My astronomy hobby always needed new solutions to unique problems, so I decided that whenever I came up with a good solution I would try to make it available to others.
