Cygnus X-1 is a galactic X-ray source believed to be a black hole. It's near the Tulip Nebula, so I pointed my home telescope there in 2020. Although the black hole can't be seen because light doesn't escape from it, there is evidence of a jet stream emitted from it, causing a bubble nebula to form nearby.

Here is the equipment I used to capture it:

Imaging telescope:
Celestron RASA 8 inch

Imaging camera:
ZWO ASI1600MM Pro

To go up:
SkyWatcher EQ6-R Pro

Frames:

Baader Ha: 160×120/" (gain: 75, offset: 15)
Baader OIII: 334×60/" (gain: 75, offset: 15)
Baader SII: 109×120/" (gain: 75, offset: 15)

Integration: 14.53 hours

Scope of the guide:
ZWO 60mm guide scope

Guidance camera:
ZWO ASI224MC
