This color image is made up 3xR, 3xG, 3xB 3x Luminance at five minutes
each. A combined total of one hour. The image was DDP'd and medium sharped
in CCDOPS v5.25 and level tweaked with Luminance added in PaintShop Pro v6. Guided with
SBIG ST4 on Celestron C102 f10 using CCDTRACK software.
This is a f6.3 image using the Celestron f6.3 focal reducer on a Celestron C8. August 03, 2004.

Construction details. Below are the images used to build the
final color image. Each one is made of two 10 minute images added. A process called
'Dark Subtract" has been done to each 10 minute image before adding. Dark subtraction is simply taking a frame with no light exposure of the same settings
as the light frame and adding it to the light frame. This process removes a great deal of noisey pixels. The Red, Green and Blue were then combined into a single RGB
image. This RGB image was processed and combined with the processed Luminance image. The result is above.
