Feb 6th, 2008 at the Vekol (I-8 east and south of Gila Bend) Astronomy
Site. This is BLM land, and part of the Sonoran Desert National Monument.
We have been having a very wet season, and the weather has finally cleared up.
We have a chance to try some new techniques with the telescope, and astronomy
image processing.
The targets tonight are Galaxies, and two Nebula.
We will be imaging in both B&W (Grayscale), and Color. This will be our first
attempt at using the FITS file format, and Photoshop image processing. The
learning curve is still very steep, but we seem to be making some progress. I am
trying to decide which type of images I prefer, the B&W images, or the
Color images.
The B&W images compare very close to what you really see through the
telescope. There is a strong tie to reality there. Color is something different.
The FITS format has been around for awhile, and is an astronomical imaging
format Used by NASA, and the ESA with the Hubble Space Telescope, and
with FITS Liberator (a software utility), NASA has given us control of the
Histrograms of the image. Photoshop then comes along and allows us to modify
that further, and then gives us the RGB color curves to play with.
The targets for today were:
M51 (The Whirlpool Galaxy)
- M81 (A grand design spiral Galaxy) - M101 (The
Pinwheel Galaxy)
and another look at M42 (The
Great Orion Nebula) with its close smaller companion M43 (DeMairan's
Nebula).
