Almost 8 Hours of 3 and 5 minute exposures, ISO 800 with the Canon. 25/26-09-14. NGC281 is 9500 light years from Earth. When the light left this nebula heading for my scope, settlements at Sand and Applecross on the coast of Wester Ross, in Scotland, were constructed. About the same time, hunter-gatherers were the first humans to reach Ireland.
