As I mentioned back in HPR 3857 "Yesterday I saw a flare" I have put together a way to take images and video through my telescopes, and more. You can do so too for under £100, assuming you have your own telescope, or add on another £40 for a nice lens for the HQ camera instead of a telescope.
Items mentioned during this recording include:
Raspberry Pi Zero W
Raspberry Pi HQ Camera
C/CS mount lens for HQ Camera
Coronado PST Solar telescope
Meade ETX-90EC - a good telescope in its day and worth using if you have one lying around but not something I'd recommend buying these days. Only available second hand.
Here are some images I took with the above kit:
The Sun in Hα using a Coronado PST solar telescope. 50 or so stacked with exposures of 20ms for the disk and one 100ms to pick out the outer, coronal features.
Jupiter using stacked images from a Meade ETX-90EC showing its spot and the moons Ganymede, Io and Europa.

Star trails using the C/CS mount lens. The bright white and red blobs are due to my headtorch and during the end fog rolled in and coated the observatory in ice in under fifteen minutes!
