I doubt it Ed, too cold at night for the few bats we have. They're about ready to hibernate, so no close coupling for them! And as for birds, the only time they'd get that close is to copulate, and wrong time of the year for that, and the birds around here don't do it on the wing. And thanks to the rest of you for your comments. John

I guess it is mostly the fires to the west of my location, and also my settings intentionally provide a darker picture so the mountains show up better.

Hi friends,
I completed a micro re-adjustment of my Canon 100-400L Mk 2 on the Canon 80d earlier today and decided to test it on the moon tonight as the night before the full moon gives a better resolution of the mountains at the 9:00 o'clock location. The image is certainly the sharpest I've ever attained. But what is most amazing is the squarish dot at about 9:15 o'clock near the left edge. It has to be a satellite, and because of the shape is most likely the ISS space station. The dot does not show up on the next image, so is not a spot on the sensor; the timing was coincidental and quite amazing. I imagine the ISS is about 300 miles high, so the image sharpness speaks well for the camera/lens combo. Hand held, Canon 80d, 100-400L Mk2, ISO 640, 1/640, f7.1 and a bit of sharpening in Picassa.

I doubt your statement's truth. I lived in that area, Billings, 50 years ago, and at that time the wild horse range was totally fenced and off limits to any cattle grazing. I'd be surprised if that has changed. At that time there was a VERY rough two-track trail that went north to south directly through the middle of the range. It was more than a bit exciting to drive on the narrow, rocky, eroded trail. More than once I wish I'd never started, but it was impossible to back up and so we went through, about 6 hours of mostly 4wd. Got lots of pics on film of course and not much good any more. But the memories live on.
Edit
Just had another memory about the Pryors. In the early 1900's a Burlington RR route went through the mountains along a path that lies more to the west of where these mountain pics were taken. The RR construction crews had to tunnel through the mountains in one location. It was that tunnel which appeared in a sequence in the movie "Far and Away" with Tom Cruise and Nichol Kidman. I've driven that old RR grade often in years past. Thanks for the Great photos and ancient reminders for good wife and I. John

Nice photos. Last time I was there in spring 2016, the roundhouse and yard was not open to visitors, you were very fortunate.

Thanks MT, good info to know. John

MT, Obviously you are very familiar with this lens, but your comment seems to imply that this lens can be tuned to the camera. Do you mean that the Nikon software is able to do this, or do you still need the Tamron Tap-in console? I shoot Canon 80d, so would I need the Tamron device for AFMA tuning?

Neat shots. Looks like the old girl hasn't been run for awhile, the date on the oil filter appears; to read 9-24-91. I'd bet that's a bit beyond FRA rules. John

Love that big country, but haven't been there in years, so these pics are a treat. Thanks, John

Thanks all, for your kind comments, John

Thanks to all for their kind replies. We spent 3 very busy photo days in Fargo in advance of this coming Wednesday's shoulder surgery (rotator cuff). Of all the stuff we did, the kites were probably the most fun. But...I don't think I'll be doing much photography for a while, as my camera/lens combos are a bit too much for single, left hand shooting LOL. John

Thanks for looking Michael, Four different kinds of apple and plumb blossoms here. John
