Brian,

 

Thanks for looking. I’m in it for the long haul and when you’ve imaged as many things as I have, that is what it takes. I still just keep a text list what I’ve imaged and what I need to complete things. Sadly, the data directory goes back to 2017 at this point for some objects.

Very nice, Dan.  Total props for persevering through 5 nights!   Holy cow, I lack that discipline.
