Feb 21, 2017 Monday – Dragoon Mountain Ranch, St. David, Arizona
Today is a “down day”, meaning we have no daytime activities planned, so the group can relax and do what they want. I catch up with my social media and email, and work on my journal entries. My blog is still behind – the last entry was for Victoria-Seattle – the first days of my travels, but at least I now have the material to write those blog posts.
It is my turn on the imaging telescope this evening, but when John and Garry try to take some flat frames before sunset, the sensor ices up. This means the desiccant inside the CCD camera is saturated with moisture, and needs to be baked so it dries out to make it effective again. This delays my imaging session of M1 the Crab Nebula by an hour and a half, however I am imaging on the 20” Newtonian Astrograph by 9:20PM and wind up my run just after midnight. Without a doubt, this is my best image of the Crab Nebula. The detail within the object is fantastic, and this is the first time I’ve imaged the green fringe around the nebula! My observing report
