Yesterday I finished my longest astrophotography project yet. Here is a three panel mosaic of the area surrounding the Bubble Nebula, or NGC 7635. You can see the nebula top middle. The whole image was exposed for a total of 18 hours over 6 separate nights. 🤯

Photographing the North America nebula NGC 7000 again, this time with all three narrowband filters I have. Turned out pretty nice after 5½ hours of exposure.
There's more information on my Astrobin page: astrobin.com/4azjsg/

Openstreetmap is reaching the point that it is just more information rich and beautiful than google maps and that is awesome

To whom it may concern,

This is a toot in email format. Trying to see if it catches on?

Have a nice day,

Kind Regards,

I love how when you're working on a remote computer, and you have to reboot it, it always takes just a little bit longer than you imagine it should.

Just enough time to make you think something's gone very wrong.

You may have three wishes.

- I wish that wish counts were represented as unsigned 64-bit integers.
- I wish that no underflow checks were performed on wish counts.
- I wish to have three fewer wishes.

I continue with the North America nebula for three hours last night. Here's the end result.

The image was taken with a narrowband filter that only passes light emitted by hydrogen glowing at a certain wavelength when exposed to the harsh ultraviolet radiation from nearby stars.

With narrowband filters it is possible to separate different elements from each other, and also - maybe more importantly - get rid of most of light pollution.
