For the past months I have been obsessing over solar astronomy, and specifically a device called Sol’Ex or Solar Explorer. It is a spectroheliograph, which allows capturing the spectrum of a very thin slice of the sun’s disk. By capturing many images while scanning over the sun’s disk with the device, you can reconstruct an image of the whole sun at any visible wavelength you want. There is a catch, though.
For a while now I have been controlling my astrophotography gear with a passively cooled Intel NUC computer, and powered them with a 110W 12V supply meant for a portable fridge. At first I kept both on the floor of our observatory, which isn’t a great long-term solution. Looking for a cheap enclosure, I bought a metal mailbox and attached it to the telescope mounting pier. At first I thought it will be great, I can run all my cables through the mail slot in the mailbox.
