What filters did you use?

For your light-emitting screen, I dumped the background down to complete black, and also gave you some stars taken by Cassini (although needing a much longer exposure) https://i.imgur.com/N8LBnzv.jpg

Anyone know what those 5 perfectly spherical objects are directly in the void directly in center of shot? Something transiting in front of camera or something else?

This image is part of a 2 panel mosaic of the Heart Nebula but I was so surprised at the detail I cropped into the very centre - Melotte 15.

I captured this with a Canon 550D, L-Enhance Filter and Skywatcher Evostar 72ED telescope. I spent about 6 hours on each panel, making this my longest ever project.

Incredible work! Is there a way to expand the top and bottom edges of it and make it an AMOLED background to fit, say, an iPhone? I'd love to make this my phone lockscreen.

And humans want to travel that at hundreds of thousands of miles per hour. Talk about taking a rock to the windshield lol.

In another random bit of info... the Observable Universe is around ~880,000 Milky Ways across.

I’ll take your word for it! I’m too lazy to do the math!

To help in understanding how far away we are from Andromeda.... you can fit about ~23 Milky Ways, or ~11 Andromedas, from end-to-end in between the 2 galaxies currently. The diameter of the Milky Way id around 105,700 ly, while Andromeda is 220,000 ly in diameter.

Whiles its an unimaginable distance on a humans scale, they are basically right next to each other on a Universal scale.

Coming soon in 4.5 billion years, roughly equivalent to 0.098 Cyberpunk developments cycles.

What kind of joke is this ☠️

Adapter that screws into the tripod mount and clamps any available rigid item, like astronaut hand-holds (blue)

That would leave a tape residue. Bungies are probably the easiest method. Most good cameras have a tripod mount. So you can bring up a mounting adapter that can grab onto a hand-hold or other available hard point.

Currently ten: seven on the ISS and three on Tiangong.

No transits, and their low mass means they produce small radial velocity changes. The star is pretty dim, too.

I suddenly have an urge to visit a planetarium.

I thought this was in /r/photography at first and I was like, this is just mean
