JKP: What? No pixel shift? :)

Anyways, the image shows stripes from array configuration randomly all over. I wonder how they will remove those artifacts when the system is in use.

How many SD card slots does it have?

More seriously, I think that researchers will be looking at small subsets of the images. It's more of a way to cover the whole sky repeatedly. And it'll catch short term changes "in advance" of an event.

donutlover: Can somebody do the math for me and tell me how many mega, giga, tera, or petabytes each image would use (uncompressed, of course)?

I couldn't find the image size numbers. They do mention 15 TB per night.

For 300 nights a year, and 10 years, that's 45000 TB. Or 45 million GB.

I don't have lens corrections available for most of my Nikon Z6 lenses. That really limits my darktable usage. Are there alternatives to the lensfun database, or will lenses start getting added to lensfun quicker?

After a little experience with it, darktable works great. Like any powerful software, it takes a while to know where controls are located and how to efficiently do the processing steps. I really like the many different ways that the sliders can be changed, both for big changes or precise adjustments.

Albert Valentino: I never got the idea of wrist straps. If I am walking around and need my hands then I need to store the camera. I also hike a lot, often with trekking poles so if I want to stop here and there to take a shot then I would have to drive into my bag.... i do agree that manufacturer neck straps are horrible on my neck. That said, i have always used soft, cushioned neck straps from OpTec and have always enjoyed them. Been using them for about 13-14 years without complaint. Also, if I want, I can unclip in about 5 seconds, which I sometimes do when using a tripod so that I do not accidentally snag the strap and knock over everything. Works for me 😃

The V2 strap does lock open, mostly. But it would regularly slide closed again if I bounced the camera a bit. Staying fully open permanently is fine. The camera is perfectly secure with the open strap around the top of my wrist and the clip end in the palm of my hand, and the camera hanging.

A friend had the PD Slide Light strap. I never considered it until I saw how he uses it as a sling instead of a neck strap, with the strap diagonal across.

This is perfect! The strap is on my left shoulder, and the camera is either on my right hip, across my stomach, or on my lower back. No trekking pole interference, and no sore neck. No bouncing camera either.

It's attached to the left camera ring and to a bottom plate.

I loved the wrist strap with my tiny LX100. Neck straps are okay when walking, but any kind of hiking or fast travel makes the camera bounce and sway.

So I got the PD strap that Chris likes for my Nikon Z6. I hated the cinch function. I finally opened the loop all the way, and stitched the two sides together with a needle and thread. That's better -- I can let camera hang down with the strap around my wrist and it's secure even though the loop is wide.

However, the Z6 and 24-70 is a bit heavy. This works fine for short sessions. And it's impossible when hiking with trekking poles -- which I always use on any trail.

continued..

fusoexplorer: How come the narrator didn’t mention the little alien in the background when he zoomed in?

Heh, from "Plaything" by Larry Niven:

...At this point the lens was eye to eye with the hitchhiking child. The child flapped his ears, made idiot faces, shouted nonsense words, and flicked at the lens with his long tongue.
THAT SHOULD GIVE THEM SOMETHING TO THINK ABOUT.
WHO WOULD YOU SAY SENT IT?
EARTH. I WOULD THINK.

Sugru cures in 24 hours, and can stick to items. This appears to be a moldable plastic, not adhesive. So it's uses are different.

Sugru has a limited shelf life before using it, I think a year or so? That's a reason I've never tried it.

The FixIts examples show it molded to itself, wrapping things, or making standalone items. I like the reusability of it. It could be glued onto another object after cooling, I suppose.
