Features of Interest
- NGC 7000 – North America Nebula; large nebula, visible under dark skies with binoculars or a wide field eyepiece for telescope – also known as Caldwell 20 (C20), the astrophotography takes the image that resembles the outline of North America map.
o - NGC 6826 – The Blinking Planetary; also known as Caldwell 15 (C15), is a planetary nebula – too bright with large telescopes to have the striking “blinking” effect seen with smaller telescopes.
o - NGC 6992 – The Veil Nebula; left behind by the explosion of a massive star thousands of years ago – a large supernova remnant as left over to be seen today in Cygnus.
o - Albireo – one of the great small-telescope showpieces in the sky; even low magnification views resolve it into a double star – brighter yellow star making a striking colour contrast with its fainter blue star.
