I feel like I need to find an on Mastodon where folks in my local timeline would generally want to see most/all of my posts. But I feel like the folks on the science/astronomy/STEM instance aren’t going to want to see a lot of leftist/socialist/anti-capitalism stuff and vice versa. And then there’s the writing and poetry and photography and…etc.

The general instances seem so…big and don’t have that concentration of specialized posting I enjoy in the local feed. I know ppl say that what instance you’re on doesn’t matter that much, but I don’t want to feel like I’m putting out a bunch of stuff that others on my instance think is spammy. Is my Twitter brain viewing this wrong? Do I just pick an instance and half my posts?

I waited and waited until the unknown woman was in the right spot; I needed her as scale for you to see the size of the chevron folds.

On a clear night in Kinlochleven in November, the Milky Way is visible down the loch. This shot took several attempts as the high road to the village runs to the left of this image. A 30 second exposure meant it took a bit of good timing to avoid light trails from the few cars which did venture down that night. This image was taken next to the slipway area in Kinlochleven.

Tomorrow will be the last day we see the Sun until February. Well we’ll likely not see it as it is forecast to be overcast. People image we have one long night, but that’s not true. We have a varying amount of twilight as the Sun skims below the horizon.

Why doesn’t he understand that I just want to stay home and hug on him all the time?

I am not a fan of winter, but man, oh man, do I love the season’s night sky. Auriga, Taurus, Mars, the Pleiades, and Orion (through the trees). #AstronomyMastodon #astronomy

Y'all making #SauropodSaturday a thing? Here's the skeleton formerly known as Apatosaurus throughout the 20th century. Somebody please give him a name soon?

So geo-types had a number of weekly hashtags going over the years on the bird site:


@annejefferson and I also had #ScenicSaturday on the blog for a while.

Do we have an appetite for any of these here? Which ones have I forgotten?

For , a wee bowl of peridot (olivine) I dug out of the world-class deposits on San Carlos Apache land east of Phoenix, AZ. We were invited and accompanied to the mining/claim site by a tribal member with tribal permission, which we were told is pretty rare. It was a once-in-a-lifetime opportunity, a great honor, and an incredible day.

I did not share the previous @APoD because I did not like them, but this #picture of the #WizardNebula is really nice. I am a big fan of the #orange colour, so this #astrophotography speaks to me.

#UMPlus - Lake Louise by Alan Dyer
Lake Louise was once a wild outpost where the Canadian Pacific Railway's rail routes terminated. Today this village, the lake and its surroundings offer some of the best hiking, skiing and sightseeing on Earth. Lake Louise and Moraine Lake generally melt in late May. The alpine hiking season starts at the end of June, you can also take pictures of.....

Hey, I just found out that yesterday (11.11) is "Columns Day" So here are some of my favourite basalt columns - the island of Am Buachaille (the Herdsman) just beside Staffa. Great trip out there recently with Turus Mara from Ulva Ferry. #basalt #columns #staffa #geology

When a snowball becomes a moon: When enough stuff accretes onto a body within Saturn's rings, they can become a Shepherd Moon. These moons rule over their own ring gaps. They also shepherd the rings, keeping them in order. If they have enough gravity, they can create disturbances in the edges of their gaps. Daphnis orbits within the Keeler Gap and as the material passes it the moon gives it little tugs creating rhythmic waves.

Give her what she really wants this holiday season. Death to the patriarchy, an ancient tome of curses from the forest witch, the hearts of her enemies, and deep pockets in every dress and pair of pants.
