Deneb
The blue-white supergiant Deneb, also called Alpha Cygni, is one of the brightest stars, with an apparent magnitude of 1.25. This star, at about 1,500 light-years’ distance, is the most remote (and brightest intrinsically) of the 20 apparently brightest stars. It lies in the northern constellation Cygnus and, with Vega and Altair, forms the prominent “Summer Triangle.”
Image captured with SPA-1 (Takahasi FSQ-106ED refractor and FLI PL16803 camera).
Total integration time of 72 minutes. 6 subs of 180s with each filter (LRGB).
On the left of Deneb one can see a part of the red emission nebulae NGC 7000 (North-America Nebula) and IC 5070.
