@ sludge...you mean YOU don't care - and that's fine.
I only have one photo of my grand parents and great-grand parents and I only have it because my mother kept a small handful of photos in an...

Canon look like they're moving away from EF-M mount and towards the RF mount for APSC camera's. Traditionally, it was the 3rd party manufacturers that produced high quality and fast APSC specific...

I've been shooting digital since 2002 and I had no idea that 1" sensors were not 1" size so Richard's article was very enlightening.

Thanks Solomon :-)

This was taken a few months ago but I only just got around to processing it.

I wonder if they have to catch the Huntsman under a breakfast bowl to take it outside or shoo it out a bathroom window with a broom

@snapa: no I wasn't trying to be smart, I was genuinely trying to be helpful. You asked for a "definitive" answer in your OP so I gave you one based on high school maths to show how much better it...

Also, JWST simultaneously takes spectrum for every pixel using two instruments. You only need to look for hydrogen signature to determine if it's a hot pixel or a galaxy.

not without a frame of reference.

No blue shifted galaxies do not contradict Hubbles law & universe expansion. You will only find "nearby" galaxies as blue shifted because gravitational interactions between nearby galaxies and...

No aerorail.

...and whining why their version...

telescope resolution is not measured by the pixels of it's sensor. It's actually measure by how far apart two point sources have to be to see them as separate entities. It is dependent on the size...

data on improvements...Hubble can see Infrared wavelengths of 0.2-2.4 micrometres. JWST IR wavelengths =0.6-28 micrometers. If we take the overlapping wavelengths (0.6-2.4micrometers, ie what both...

I can't tell if you are making a joke or serious.
If you're joking...hilarious :D
If you're serious...The "sunstars" are actually diffraction spikes. It's the light bending around the arms holding...

...even on relatively clean panels the power needed to compress the air is going to be vastly greater than the energy gain from marginally cleaner panels (remember that mars is 1.5x further from...

Humans have been sending landers and rovers to Mars since 1962 (first successful lander by the Soviets in 1971).
Do you really think that despite all that time, NASA suddenly realised that dust was...
