Hi All,
Tired of the Crescent yet?
Last night was good enough for me to collect color data for my Ha image. I constructed my images using a combination of techniques. The image is a Ha(Ha+R)GB image. I shot 2 hrs of Ha and 1 hour each of RGB. After calibration and registration I combined the Ha image and the R image using the "lighten" layer combine in Paintshop. Then i combined the new R image with the G & B images. After an intial color balance, i them did a "luminace" layer overlay with the Ha image as the luminace image to bring out the detail better and reduce star bloat by over half. Here is my shooting data for the image.
Scope: Stellarvue SV-102 APO @ f/7.8 (native focal ratio)
Camera: Starlight Xpress HX-916 1.3MP monochrome CCD
Exposures: Ha(Ha+R)GB - 120
120+40):30:30 - All unbinned
Mount: Losmandy G11
Guiding: ST-4 w/SV-80/9d Guidescope
Filters: Astronomik Type 2 LRGB & 14nm Ha in a Homeyer MFW
I used Maxim DL for image aquisition and processing. I also used Images Plus for image calibration, and Paintshop pro for the layering.
