ASTRO: NGC7331 LRGB, hybrid shot
I combined an unfiltered luminance shot I took last summer using a U8300
from my AP180EDT f/9 using an Apogee U8300 with RGB data taken the past two weekends using my Stinger 450 classical cassegrain with reducer (f/7.4) and Microline ML4022 This is a total of 14H 20 M exposure with 8H30 minutes being Unfiltered Lum and 5H50Min being RGB the seeing was pretty decent for all the data collection The big cassegrain is very sensitive to wind so the star diameters aren't as tight as the seeing would have permitted. Gotta get that guy into an observatory to shield it from the wind to get the best performance from it but that's another story.... http://www.narrowbandimaging.com/ngc...2_rgb_page.htm |
