ParticipantDon, this is awesome!

ParticipantThank you Keelin

ParticipantA couple of things about eclipses. I got my eclipse dates and other information from this site:
Move your mouse over “Sun & Moon” and you will see all sorts of information including eclipses. There should be a place to specify your location. I got very detailed information about the eclipse specific to New York including phases of the eclipse and the azimuth and elevation of the moon at those points.
Now, speaking of elevation, Hans, I would have loved to put the eclipsed in some context, as you suggested, but it was difficult because the moon was very high as seen here, almost 70 degrees. I wanted to use a telephoto, so the moon is a bit bigger than a dot, but then the context needs to be at some proportional distance. For example, in the shot with the skyscrapers, they were at 11 km from me, so that ratio with the moon worked well. But if the moon is high up in the sky it’s a different story, cannot find a context at that distance. So the only thing I came up with was the combinations with the Gemini stars, which were really calling for it.
Incidentally, it was very cold, 7F/-14C, and very windy. Reminded me of Yellowknife.

ParticipantA distrail is the opposite of a contrail, still I thought this is the best thread to post this. I was taking a time lapse of clouds passing in front of the moon, when this happened. The time lapse is too fast, so I had to create a slowed down version. That slowed down version is not much faster than real time. Interesting how quickly these things happen.

ParticipantThe little cumulus-like clouds produce precipitation in the form of ice crystals and strong air currents below drag those precipitations away. Very ice shot!

ParticipantHi Laurence, this is an outstanding picture helped by the combination of circumstances. The sun is low, so no filter needed, therefore you can capture the landscape. Beautiful, thanks for sharing!
I am in a bit of a panic. We have a lunar eclipse coming in just over a week and I am still thinking what kind of shot(s) to take. The moon will be pretty high up, so if I am using a telephoto to get some moon details, it will be hard to get some landscape around it. Oh well, I still have time to think. (And it may even be snowing, who knows?)
Will the lunar eclipse be visible by you?
I caught on “film” a partial lunar eclipse in the early 2018. The moon set well before totality. But it looked great anyway.

ParticipantFolks, thank you all for your compliments and encouragements to show more. I am glad to do that. Here is a link to the trip album I created. Not just the Aurora, but also a few “frozen” moments. And a Bullock’s Bistro interior pano, maybe Don can see his signature :-)

ParticipantFascinating, Laurence. Thanks for sharing. There are two accepted theories about how rain forms. One, applicable to CB clouds, is that it all starts as ice crystals that grow at first by direct deposit of water molecules onto them. At some point,they are heavy enough to start falling and they grow by accretion, the tiny droplets they hit freeze on them instantly. As they get lower, the temperature of the air increases above freezing and they begin to melt. If they are very big, some survive and hit the ground as hail.
How big can the hail balls be up in the clouds? Maybe 15 cm. The updrafts can be 50 m/s and will keep these big balls up. In fact they can go up and down more than once as they get picked up by different updrafts. Mind boggling what happens up there.

ParticipantI think it’s a fallstreak hole. The reason is that those “cirrus” clouds are below the altocumulus, You can see that on the right end of the gap.
