This shot of M101 is from the @RAOastronomy Baker-Nunn telescope. M101 is visible below centre. The arrows point to other galaxies that I was able to identify in the image.
@CountZero Thank you!
Spectroscopy tells us many things including what things are made of. The dark lines in this spectrum of Aldebaran are made by the various elements in it. Each element has a unique set of lines which identifies it.
A society that places things (firearms, low taxes, convenience over safety, religious dogma, etc.) above its children is lost.
@DialMforMara There are days I wish my classroom was a Faraday cage...
Another frustrating night of guidance problems...
@djsundog My first machine had 4k of RAM. You learned to write tight code...
NGC 6826 is known as the blinking planetary as its brightness is such that in a small telescope it seems to disappear or blink when you look directly at it. It's about 5000 ly distant.
@Canageek neater than mine...
A focusing mask is often used in astrophotography to ensure a sharp focus. With this mask, when a line appears in the middle of the created image, the telescope is focused.
@askans It will add brightness making the object seem brighter than it is. It would provide an incorrect value yes.
@jaller94 I'm currently mucking about with the data and Blender to see if I can make it more 3D.
@askans it adds light to the target which means any photometry on the target will now also include the light from the satellite.
@djsundog I seem to collect various TRS-80s.
Artificial satellites are a bit of a hazard when imaging the sky. This one went right through the target, making the image useless.
@jaller94 the data was created with a Barnes-Hut simulation on the Swinburne supercomputer. The individual frames were created with GNUPlot. I can't remember what software I used to put them into an animated GIF.
@kmicu They're just around the block so to speak 😀
The space between stars in galaxies is so great that when galaxies collide there are hardly any collisions if any at all between stars.
