APOD: 2018 March 13 - The Complete Galactic Plane: Up and Down


UpDownGalaxy_Moophz_2048.jpg


Explanation: Is it possible to capture the entire plane of our galaxy in a single image? Yes, but not in one exposure -- and it took some planning to do it in two. The top part of the featured image is the night sky above Lebanon, north of the equator, taken in 2017 June. The image was taken at a time when the central band of the Milky Way Galaxy passed directly overhead. The bottom half was similarly captured six months later in latitude-opposite Chile, south of Earth's equator. Each image therefore captured the night sky in exactly the opposite direction of the other, when fully half the Galactic plane was visible. The southern half was then inverted -- car and all -- and digitally appended to the top half to show the entire central band of our Galaxy, as a circle, in a single image. Many stars and nebulas are visible, with the Large Magellanic Cloud being particularly notable inside the lower half of the complete galactic circle.

Something a little different. I recommend watching this for everyone, it will probably make you smile unless you're an asshole.

That's awesome. Going to figure out how to collimate my XT10 and do something similar w/ Jupiter for my neighborhood soon. Some pieces have been missing since the move, think I've got everything but the finderscope now. I suck bad at collimating it though, might have to take it to find someone locally to help.

The type of telescope he's using was first made for groups/individuals to make and have a cheap usable telescope. The dob. Home made dobs are kind of drying off now that the availability of pyrex mirrors has dried up. Don't have a dob currently but did at one time. Down to refractor for planetary and a newtonian mounted on a eq mount for deep space. Kind of suprised he had a large dob living right in the city since they're normally used for deep space viewing and the lights would kill that off pretty bad.

Lots of clubs have regular meetings and if you show up to the regular viewing you can normally get help collimating if you get there a little early. Like everyrthing tho some people can turn it into nuclear physics ordeal.

Whats the relation of Nova Carinae to Beta Carinae? I know Beta Carinae is bright as fuck.

Anyone here watch Isaas Arthur on youtube? Dude has some amazing shit about space.

I watch all of Isaac Arthur's stuff. I usually let it pile up for a month or two then binge watch him and pbs space time.

Launching the thing just means those people have to find something new to do.

On Isaac Arthur. Dude is great. I think he needs to work at space x or NASA. I've listened to so much of his stuff his voice doesn't register as having an impediment anymore.
