Re: APOD: Perseid Outburst at Westmeath Lookout (2021 Sep 24)
I'm not annotating this image, because if I do, I will have to upload it to my computer. And once I upload it, I can't remove it. ... So any image I upload is going to stay in my hard disk forever, and this one wasn't worth it. Ann That's a mystery to me as well — why you can't delete image files. ...

The photographer, Pierre Martin, posted this same picture in the Spaceweather Photo Gallery on Sept 20. He included a relatively lengthy description of the circumstances.

Re: APOD: Rings and Seasons of Saturn (2021 Sep 19)
Saturn was in conjunction with the sun on Sept 17, 2009, so on Sept 4, the day of ring plane crossing, it was a daytime object that would have been essentially impossible to see or image from earth's surface. Before and after Saturn disappeared into the solar glare, the rings looked like a thin brig...

Re: APOD: The Deep Sky Toward Andromeda (2021 Sep 08)
Thank you, Ann, for your labelled version of this picture ! Without it I was confused. On a PC at least, mousing over the APOD image reveals the annotations. But I think this doesn't work right - or at all - on an iPad, for example. On my iPad, I was able to tap the image to reveal the annotations....

Of course, M31's satellite galaxies, M32 and M110, are also present in the picture. M110 floats above M31 while M32 is like a puffy star below-right of M31's core. There's another galaxy too, NGC 404, the "Ghost of Mirach," which is a faint smudge just above the bright star Mirach (Beta An...

But inspection of the high resolution image (which shows a lot of sta...
