Clear skies in Redmond plus a William Optics Redcat 71 (350mm f/5) with a ZWO ASI294MM Pro monochrome camera on a ZWO AM5 mount = The Heart of Redmond. This version of IC1805 was shot from Redmond near the Microsoft campus. I shot around 8 5-minute exposures per red, green, blue, sulfur, hydrogen, and oxygen filter for a total integration time of around 4 hours.
