I think Charles’ Wain predates our monarchs of that name but it’s most appropriate for this weekend.
It undoubtedly does so. The Wikipedia article goes into at least as much detail as you are likely to want. In particular, it has the same name in a number of North Germanic languages.
…and there is Cor Caroli…

Now well-placed for images of the starfield.
Tucked inside the handles of Charles’ Wain. You can’t miss it.An equivalent way of saying this, though it needs considerably deeper understanding of QM, is that the uncertainty principle follows inexorably from the properties of the Fourier Transform.
The linkage is that a quantum state is fundamentally a function of complex numbers, whereas in classical mechanics everything is purely real.
Some of you may know why that the question of the existence of uncertainty principle relating energy to time, and why it has the same value as position-momentuum relation is very far from obvious, largely because time is not a quantum operator. A fascinating journey down a rabbit hole finally gives a good answer to that question, but the reasoning is very far from obvious.
Hacienda San Jorge in Los Concajos perhaps?
The architecture and colour scheme look rather familiar.
On my last trip to La Palma I took some images in Sloan i’, r’ and Johnson V (I don’t have any other JC filters nor Sloan g’) of the M67 Landolt field. The primary interest is photometry calibration but I also realised that tri-colour images should be possible, even though they may look odd.
The images have not yet been processed but I will report back later.

Now you mention it, iota Cancri is my favourite double star. Similar to Albireo but rather prettier IMAO.
Pi Cephei is was double star of the month according to https://www.webbdeepsky.com/double-stars/object/pi%20Cep
Pi Gruis is, by all accounts a fine double, but too far south at -46 Dec for UK-based telescopes. I may give it a try when I return to La Palma.
Pi Sco is visible from most of the world. The primary is a spectroscopic binary and the secondary is rather difficult (though well separated) at mag 12.2. The primary does show eclispes, but with a depth of only 30mmag it likely presents a worthy challenge to photometrists willing to stretch themselves. The period is 1.57 days. Anyone up to it this summer?
Sounds good. Often thought I should attend.
The event is always fully booked before I receive my supply of round tuits and generally before I know whether I will be in the country at the time it is held.
BTW I was present at the British Concorde’s (002) maiden flight from Filton, Bristol, which happens to be 54 years ago today!
I have been in the cabin of a Concorde. Sadly, it was travelling at Mach 0 in a hangar at Duxford, just down the road from here.
If anyone would like to replicate my experience, please let me know in good time and I will show you around the district and, in particular, introduce you to the excellent pub “The Plough” in Duxford.

Given that serious astronomers express stellar luminosities both in ergs/second and in a inverted logarithmic scale to a bizarre base, I am inclined to cut journalists some slack.
I will get in contact soon. From the GUI point of view, APT works rather well in setting the ellipse parameters.
I’ve just watched the BBC1 lunchtime news about this flyby. Under the name of each astronomer interviewed about this NEO, the BBC gave them the title ‘Astrologer’.
Argh!
Alex.
Reclaim the night!
With a concerted effort in the public media, astronomers could call themselves astrologers and hoi polloi would begin to think of astrologers as scientist rather than mystics, entertainers and/or charlatans.
Vocabulary has changed radically in the past. Consider the terms “nice”, “gay” and “hacker”.
Might be difficult though …
Richard: thank you for revealing the term “capsule aperture” to me. I may well contact Russ and suggest that he consider adding them to APT. He has been very welcoming of suggestions for enhancement in the past.
For only slightly trailed images (major/minor axis < 2, say) an elliptical aperture works very well – as measured by comparing the results for untrailed subs and circular apertures with their trailed counterparts of the same field and a carefully chosen elliptical aperture. If you examine some of my entries in the VSS database you will find some examples of elliptical aperture photometry.
