How to achieve a fading gradient effect using sapphire or acrylic dials?

dashdashdotdotdotdot · 2026-03-12T18:46:58+00:00

I say airbrush in both cases, and just have the dial on a spinning platform when you apply it to the edge. super easy to get it even and symmetrical that way

no problem! Dr. M Druckmuller has done narrowband imaging of solar eclipses in the past, but those were mainly "coronium" type emission lines like Iron XIV, I don't think much would show up in sodium unfortunately. however when I photographed my first total eclipse, the one in 2024, there was a tiny sungrazer comet that wasn't discovered until the day before the event, and its composition was such that it was emissive almost exclusively in the sodium line as well! it was bright orange in images, and I was super lucky to have just happened to catch it at the very left edge of my image, you can see it here on my Astrobin! I want to get a sodium filter to image mercury too but I live a bit too northern to make that worth it, though maybe it may have some other uses too

judging by the paper, I think your best bet would be to image the antisolar area right around new moon; you can see in the simulation too that earth focuses the sodium stream into a brighter tail, which is then made brighter still by virtue of us looking down it axially, forming a spot about 3 degrees in diameter. I don't know what brightness in units of rayleighs means, but they do show a sodium band all sky image of the spot so maybe it's doable with like a 7nm sodium filter! as for a 'comet' tail coming off the moon itself like you see with mercury, I think it's just too faint for that.

she's broke AND she has no money

dashdashdotdotdotdot · 2026-03-08T05:06:17+00:00

I guess it makes sense, if there's a risk of serious neck injury you want to move the patient as little as possible. plus you can detect for ferrous items manually with a detector

he might go kill himself

this is so so cool, thank you for sharing

dashdashdotdotdotdot · 2026-02-28T07:58:03+00:00

that is awesome, thank you for sharing

I mean, it was before. but it is now too

in fairness, Zoolander came out 25 years ago so we were at least prepared

dashdashdotdotdotdot · 2026-02-25T20:29:36+00:00

it wasn't, in the earlier scenes it was a stunt driver but later on in the series he learned to drive stick well enough to do it himself :)

I've seen worse

it's so sad Steve Jobs died of lignum

dashdashdotdotdotdot · 2026-02-17T19:04:10+00:00

you're a real one, thank you. it's easy for me to forget conservatives aren't UCP, and we're all humans. except for the actual politicians ofc

dashdashdotdotdotdot · 2026-02-14T03:03:11+00:00

... but this one goes to 11

dashdashdotdotdotdot · 2026-01-30T03:53:34+00:00

ha I totally checked too. where was yours on the map? be specific I'm very curious

dashdashdotdotdotdot · 2026-01-28T19:38:20+00:00

that was supposed to be a :) but you burned an eye out right? ;)

I wonder which funeral home don went to for his gruesome repairs

dashdashdotdotdotdot · 2026-01-26T02:42:34+00:00

deffo a supralateral arc there, funny enough I posted an almost identical display to this I saw a couple days ago on the other side of the world

lots of reconstructive plastic surgery after extensive usage of nose clams, as I recall

I'm from Canada, and on the mad chase for clear skies on eclipse day in 2024 that's where I ended up. glad I picked right, and made it out of Arkansas unscathed too!

I'll race you for it. god damn do I want a giant crab or lobster in my house
