Anyone know the total number of satellites currently in space? The numbers I see cite @planet4589 but haven't seen him post any updates here recently, and not sure where to look for any authoritative count. Was just trying to quantify this in an intelligence way for my students. (random craptastic, non-attributed Internet search says 9,450-ish Starlinks, plus 2,500 odd other things in the sky... but since no attribution, no idea if it's hallucinated or not).
(Update: 9,634 Starlinks per @sundogplanets , at least today on 2/3/2026)
Update to the update: Jonathan McDowell has this stats page, perfect!
For the first time since 1972, humans are headed back toward the Moon 🚀
NASA’s Artemis II will send 4 astronauts on a 10-day journey around the Moon to test critical systems and pave the way for a future lunar landing.

While I was waiting around for some aurora activity earlier this week, I played around with the OM-1's live composite mode while using my fisheye lens. I've made star trail images before, but it's way more convenient to do it in camera rather than having to stack in post-processing. The clouds created a surreal effect as they moved across the frame. This image is incomplete, as a long exposure would have shown better trailing, but I like the way it came out.
Olympus OM-1.1
Live Composite of 8s exposures
Olympus 8mm fisheye PRO @ f/2.0
Probably 30-40 minutes of exposures

Horsehead and Flame Nebula are a rite of passage for any new camera gear, so I pointed my ToupTek585M at it and snapped away with L, R, G, and B filters. As usual, Alnitak (the easternmost star in Orion's Belt) is a problem. At some point, I'll try again with shorter exposures, but for now I'm...showcasing how bright that star is. Let's go with that.
