Large photos do take up a lot of space, especially when you also store a RAW file with the Jpeg. Higher end smartphones offer that ability that days but I bet hardly anyone actually knows what they are and how to use them. I've been utilising RAW files for a very long time. Photoshop added built in support about 10 or so years ago. They are great files as you are not restricted by the limited contrast, light balance, saturation etc as they are the camera sensor's raw data, whereas every image you normally see on a phone or camera has alteady been processed and filtered by the onboard processing.

And yeah, those deep space radio telescope require a huge volume of storage. That single image released recently showing one area of the sky in great detail used Petabytes of data. I can't imagine the setup needed to actually process that data and create the final image. You couldn't load it in any home system. It would need a server farm.

The telescope has to be locked on to the North Star & then be capable of tracking to compensate for the rotation of Earth through GPS. This then allows a High Resolution & Quality Camera to take snapshots of the same relative spot in Space from our planet.
All the captured Images are then run through Lightroom & exposed to each colour of the see-able spectrum to build up the finished picture. Hours upon hours of work using high End PC's provide satisfactory results. - It's a dedication most folk couldn't begin to appreciate.

If you use Facebook, I do recommend you look up Jon Chard and see some of the fantastic Photos he's captured. Particular areas within the Andromeda Galaxy are just mind blowing & if that doesn't float your boat, some of his photos of our own Milky Way Galaxy are equally as stunning. Looking up at a night sky from the New Forrest in Holbury (Near Southampton) shows a clear band of stars that make up the disc of the Milky Way Galaxy we are a part of. - Just Phenomenal!

Equally, his wildlife shots & family shots of two beautiful daughters are just as breath taking in their own rights.

I was referring to the James Webb telescope which is in deep space and not effected by Earth rotation. It orbits the sun, not the Earth. And it's images take a lot more to process than most images captured by a traditional telescope.

BTW, I know many do use Lightroom, and I have as a glorified image library tool since it launched, but it's no replacement for Photoshop to really work on an image. Lightroom has recently seen a big update that has added some much needed extra features and abilities, but if you have been using Photoshop for years it feels like trying to edit images with a hand tied behind your back.

BTW, your link has made me remember I was going to look into getting a proper T ring DSLR adapter for my telescope and Canon camera. To date I've just used an eyepiece adapter that came with my telescope. It does work but not like having the camera using the scope like an actual lens attached directly. I have managed some great images of the moon this way and some images of Saturn. But my telescope isn't that great. Just a starter one that was a couple of hundred to use with my son. Really want one I can hook up to a computer and have a proper tracking tripod head. But that's expensive.

What are your pictures of Saturn like?

[Harrison]

I've not got around to trying Saturn properly yet. We did see it through the telescope but not taken any pictures.

Just looked it up and it's most visible in August when it will be the closest to us. Need to remember that and try to get some good shots.
