One of my podcast pet peeves.
The other is repeats that aren’t obviously labeled as such (even in the show notes). I’m a loyal listener who’s been listening to every episode for over a decade. My listening time is limited.

It’s just going to be bulldozed in 2029 as part of the White House Historic Restoration Project, so it doesn’t much matter.

Hmm. 90 min / 360° is .25 min per degree. Times 60 s per min is 15 sec per degree, which is 7.5 seconds per half degree.
However, I think that would be from the center of earth, which would also mess with the angular size.
In reality, if straight overhead it’s about half a second. This was ~1s.

That’s a beauty! I only had a 150-600mm lens with me (on a shaky tripod) this time. But my profile header pic and this attached was perhaps my favorite, with the telescope.
