NGC7789 Caroline's Rose Cluster in LRGB.

All imaging took place at my remote observatory at e-EyE, Spain.

This image comprises 2 hours and 5 minutes of exposures in 250 exposures in total, each 30 seconds long. To be precise:

L = 100 x 30s
R = 50 x 30s
G = 50 x 30s
B = 50 x 30s

This image exploits short exposures in order to prevent over-saturation of stars and in order to avoid problems with the Moon.

Equipment and software used:

Mount: Avalon M-Uno
Telescope: Takahashi FSQ-85ED
Camera: QSI 660wsg-8
Autoguider: Starlight Xpress Lodestar X2
Filters: Astrodon E-Series Gen2 LRGB
Capture Software: Sequence Generator Pro and PHD2
