This morning a bashed-up juv Blue Tit appeared on the bird-feeder closest to the window. Its plumage was generally all dishevelled, and its throat and the left side of its neck looked bare and red. I tried to get a closer look at it but my downstairs binoculars couldn't focus closely enough. So ... I put the bins in " monocular" mode with the "adjustable" side to my eye and swizzled the eye-lens dial, and that got it into sharp focus even though it was only about 3 m away. I've done it before in similar circumstances ... it works very well. In the close-up view,the Blue Tit in question had raw, red-tinged bare skin all over its upper breast, the front of the neck and the left side of its face. But it seemed to be operating well, in spite of that. But what I thought was ... I wonder if everyone knows that "using-it-as-a-monocular-and-twizzling-the-twizzleable-eye-lens" thing ? Well, if you didn't, now you do .... go on, try it today ! You never know when it might come in useful. But don't forget to readjust it once you've finished ... or else next time you use them "normally" the image will be blurred. I know, because it's happened to me. Right then .... now you've got the Know-How ...... ..and here's the words video so you can sing along .... Actually, constellations don't stay the same .... each star usually has its own "proper motion" and over the millennia the shape of the constellation will change to a greater or lesser extent. In addition to that, stars can change their magnitude both in the short or long term. So there.
