Every lens would have to duplicate stuff that it doesn't currently have. So you would have multiple complex things and one simple thing. Compare that with now where you have one complex thing and multiple simple things. Soooo, no!

filter?

I guess the dynamic range is dependent on other factors than just sensor size. I don't know though. The table at the bottom. I don't know what 'low light ISO' is.

The charts show that at higher ISO the dynamic range is reduced. You can compare different cameras by adding them to the same chart. At say 1600 ISO it is clear that there is a range of dynamic ranges so it's clear which camera would be better at that ISO

Yes I agree but I think it's abit chicken and egg and I had to decide which to choose initilally. It's called arethere.photos because if it were well known and well used then if you had been at an event then you might expect to see that event on arethere.photos and there would be a map showing...

That's the thing yes, advertising. It's difficult to know who the customer is for a start so you can spray expensive adverts all over the place and when you do the sums if it's £0.50 per click and only 1 in 100 take up the service it's very hard to make money. Without advertising it has to be...

If you get your own domain name and create a website initially no one will know it exists. Wix et al sell the idea of having your own galleries and shop front presumably because they get lots of money for that. What is the purpose of uploading the photos? Presumably it's being able to sell...

Hmm.

I had to think about that. I can see what you mean but I think it depends on the subject; if it were a blanl canvas then I might agree but imagine the subject had detail on the scale of the pixels, so that each detail (like a star point) fell on just one pixel. In other words although your...

If the number of pixels is the same on both sensors then each pixel will be smaller so less signal and more noise.

One of the older Ioptron skytrackers but any will do.

Hauled my carcass out of bed at 4.30 to take a picture of the morning comet c/2022 E3. It's very high in the sky in the early hours and almost overhead by 6am. With binoculars it's easy to find if you just sweep around and it appears as a fuzzy blob the size of the moon and without colour. A...

Just before dawn. I haven't seen it yet because it hasn't been clear at that time yet. Probably unspectacular but it is a fast one so motion again the background stars will be visible with a telescope and make trails in long exposures. The first image here is from a similar brightness comet...

Bose have an app that they say can be used to stream various services to your speakers... https://www.bose.co.uk/en_gb/apps/soundtouch.html

As I said earlier make MEASUREMENTS to determine what is lacking rather than just guessing!
