It's been a while since I captured the Cygnus Wall, but it was fun to return to it. I used my Explore Scientific 127MM telescope and ZWO ASI1600MM camera.
It's part of the North America nebula and 2,600 light-years from Earth.
It's processed in the Hubble Palette, a false-color representation, but useful to see the separation of hydrogen (gold) and oxygen (blue).
Follow me on Instagram if you would like to see what's possible to be captured from our own backyard and to see what telescopes I use.
This is the equipment I used to capture it with:
Imaging Telescope: Explore Scientific FCD100 127mm
Imaging Camera: ZWO ASI1600MM
Mount: Celestron CGX
Guide Scope: Orion ST80
Guide Camera: LodeStar X2
Electronic Focuser: MoonLite Telescope Accessories

Note: A lot of people ask this, but how does my telescope stay on target if the Earth rotates. My camera and telescope sit on a motorized mount and with the help of computer software, it stays on target.
