More cishet folks need to look at this meme hard. Don't just hit favorite or boost and then pat yourself on the back as an ally. Go back and look at it and think about what it is saying. If you hear a snide or dismissive comment about trans people, speak up and straighten that shit out with some truth. Don't remain silent. Everyone will be targeted eventually, even the comfortable white cishet folk. /rant
I think this is the last of my 2025 unprocessed data series. Data captured July & Aug of 2025
I have unprocessed 2025 data for other targets. But I hope to capture more on those this spring, before processing.
vdB130: area of Hydrogen nebulosity in Cygnus constellation, near Crescent nebula. It includes pretty orange & blue stars.
6" refractor w/mono CMOS camera. About ~20min each in R, G & B. Target really deserves more exposure time.
And last but not least, HOLY SHIT the stars were fucking incredible last night!!!! (No auroras visible from here but the stars were so good who cares)
(Lots of satellites, of course. Sigh.)
I have an email from my collaborator saying he just re-ran the CRASH Clock code, and we are now under 3 days for the first time ever! Good work on bringing us that much closer to Kessler Syndrome, everybody. Special congrats to SpaceX on that one. Hope you take full credit when it starts!

Dear computer companies,

Happy (Merry?) Equinox today… the Sun crosses declination 0º northward today at 14:46 Universal Time (UT)/10:46 AM EDT, marking the start of astronomical Spring in the northern hemisphere, and Fall in the southern.
In the 21st century, the March Equinox falls mostly on the 20th, though it stopped falling on the 21st in 2007, and will start occasionally falling on the 19th in 2044.

The biannual equinoxes are also the season where satellites way out in geostationary/geosynchronous orbit flare and eclipse, as they hit and then emerge the Earth’s shadow. https://www.universetoday.com/articles/tracking-satellites-through-geosat-eclipse-season
We may also be in for enhanced aurora this weekend, as what’s known as the Russell-Mcpherron Effect comes into play around the equinox, opening fissures in the Earth’s geomagnetic field allowing for space weather to come streaming through.
What you can’t do is balance an egg on its end any better during the equinox than on any other date. Plus, the ‘equal night’ naming is only approximate, as the true ‘equilux’ for a given location lags or precedes the equinox by several days. GEOsats see the ‘tip’ of the Earth near perpendicular: https://science.nasa.gov/earth/earth-observatory/seeing-equinoxes-and-solstices-from-space-52248/
The Vernal Equinox 2026
The date of the Vernal Equinox is often given as 21st March, but in fact it has only been on 21st March twice this century so far (2003 and 2007); it was on 20th March in 2008, has been on 20th March every spring from then until now, and will be until 2044 (when it will be on March 19th). I'll be retired by then.
