The Ford dealership couldn’t find anything wrong with the truck. They ran all kinds of tests, adjusted fuel settings but nothing major. The check engine light is off and that is good. They only billed me $100 after working on it all morning. I was expecting a lot more. The NAPA in Ajo wanted to replace all the O2 sensors (there are 4 of them) and that would have cost between $500 and $1000. I am glad I waited. Ford thinks it may have been a fuel problem of some type. That makes sense, it happened just a few minutes after filling it up at the Shell station in Ajo.
The moon is getting brighter and staying up longer but I still put in a full night of astro last night. I stayed up all night, mostly because I wanted to image the Trifid Nebula, M20, with the C8. At this latitude, M20 rises to nearly 35 degrees above the horizon, which is still pretty low but in South Dakota I would lose another 10 degrees. M20, at about 20 arc minutes diameter, is just the right size for the C8 at 1200mm focal length.
