Sagittarius Star Cloud

[tornado33]

Was windy but clear last night so got out the Canon 400mm for.6 USM L series lens and turned it on the Sagittarius Star Cloud B86 area.

Image is 8 x 5 mins ISO 800. Taken with EOS Ra camera no filters. The 30x live view makes accurate focusing so easy especially if i set camera to Manual set shutter to 1/60th or faster. That way the star image on the screen refreshes very fast and bright stars not too large. With that done I set camera back to bulb establish WiFi connection to laptop set iso and timer then start imaging.

Hand guided via 80mm guide scope and guide camera.

Cool, looks like a HST shot (https://www.nasa.gov/sites/default/files/thumbnails/image/hs-2015-02-a-hires_jpg.jpg) of the Andromeda galaxy :D

Make sure you click on that core!

Fantastic. The stars must be so close together in there compared to out here in the Galactic burbs.

Nice one, I love it, that's a shed load of stars! :lol:

The astronomer Carl Sagan famously said that there were more stars in our Universe than grains of sand on the Earth's beaches.

Are there more grains of sand than stars?

Using the latest geological studies, scientists calculated the total volume of sand on Earth. They estimate that Earth contains 7.5 sextillion sand grains. Astronomers estimate there exist roughly 10,000 stars for each grain of sand on Earth.

That's .... a lot .... of stars! :eyepop:

Thanks all. Yep and even if one in a billion stars had a habitable planet that's a heap of habitable worlds out there.
Camera technology now is amazing. I can barely see the Milky Way from Newcastle, the sky is so light polluted yet this detail can be pulled out in 40 minutes :)
