The seven sisters


The 7 sisters is my favorite sight in the night sky they look so wonderful up there shining away could stare at them for hours and never get bored with them. This shot was taken from 48 exposures then stacked with 10 dark's 10 lights and 10 bias.

WHAT are you talking about mark.. Darks are shots taken with the telescope capped off they are used to subtract the noise from the images Lights are taken by putting a white cloth over the end of the telescope shining a 27 led torch at it and take the same as the Darks and Bias shots are taken at the fastest shutter speed the camera has. They all get subtracted from the final image to keep it clean and nice. They are a pain to do but worth it.
