NGC457 Dragonfly Cluster and NGC436 Star Cluster in LRGB
NGC457 Dragonfly Cluster and NGC436 Star Cluster in LRGB.
All imaging took place at my remote observatory at e-EyE, Spain.
This image comprises 1 hour and 46 minutes of exposures but 212 exposures in total, each 30 seconds long. To be precise:
L = 62 x 30s
R = 50 x 30s
G = 50 x 30s
B = 50 x 30s
I intended on capturing 100 Luminance exposures but the Moon was about to set and another target called. This image exploits short exposures in order to prevent over-saturation of stars and in order to avoid problems with the Moon.
