Small Camera & Big Universe

I don’t think those photos are taken with such a small camera. First of all in a city there are too many lights to get a clear view of the sky, hence all large telescopes are on high ground (> 2000m) and away from cities. Also the atmosphere has a big influence (high altitudes -> small density -> better view).

Awesome! It’s always amazing to see this big place we actually live in. What time does it take to take just one picture?

takes hours or even days

But how is this possible? Is the camera following the earth rotation? Otherwise it would just show stripes instead of stars!?

Agreed. I’m having the same question as well. As pointed by Nickys, one of it does look a bit like a wallpaper.

I didn’t mean that it’s not an authentic photo taken by FlashTang The mountain lion wallpaper is still a photo of the same galaxy! And the galaxy still looks the same

Maybe one shot requires multiple days? Something like pause and resume when the moment is right?

Great images!

lol….....

Some of the photos showed here says 8min and (20min x 30) exposure times. Not sure how it is possible with multiple days of re-centering same guidestar.

It is a lie, don’t believe the telescopes, sky is always plain I tested it from my room.

With astro calculations where exactly to point to it’s possible, why not? It must be very hard getting that sharp photos since it’s very delicate.

^ Yeah, should be possible with GPS though. But think about solar system’s movement that happens in a day – oh, glad its not my busniess!

Well nothing that can’t be calculated

Naturlich, Mat!
