Telescope | Nikkor 180mm f2.8 ED AIs lens at f 2.8 riding piggyback on the LX 200 classic |
Camera | Canon XT/350d modified with Baader type 1 filter by Hap Griffin |
Exposure | 29
ten-minute sub-exposures in RGB with 6 fifteen-minute subs at iso 1600 in H-alpha. |
Guiding | PHD Guide from Stark labs with Meade DSI pro I on Meade 12-inch LX 200 Classic at f/3.3 |
Software | Images acquired, calibrated, stacked and color corrected with Nebulosity 2.3.7 from Stark Labs. Further processing in Photoshop CS 3. For this image, I took a lot of RGB, searching for the nebulosity, and then added an hour of H alpha as tone mapped luminance with red and blue to finally bring out the details and color. Star color was extracted from the RGB stack and added in final processing. |
