NGC 7000 Mosaic

NGC 7000, commonly known as the North America Nebula, is a large emission nebula located in the Cygnus constellation.The aim of this work based on 24h 20′ integration under Bortle 4 sky, is to show deep details of this common nebula and the surrounding space area. The presence of a well resolved structure of three galactic, true planetary nebula and Ha nebulosity patches respectively K 4-55, GAL 084.0+00.8 and Herbig-Haro 651/652/653 was also noticed, adding to the celestial tableau alongside NGC 7000.The galactic planetary nebula K 4-55, located at the celestial coordinates RA/DEC: 20h45m10s / +44°39'14", is a fascinating region of our galaxy. With an apparent magnitude of 16.6 with 71 arcs apparent diameter. Discovered by Acker, A. and al. in 1992, this nebula has captivated the interest of many in the astronomical community.

The true planetary nebula GAL 084.0+00.8 discovered by Lockman and Felix J. in 1989 presents a complex structure formed with 8 celestial objects located at RA/DEC: 20h45m38s / +44°14'56".

Herbig-Haro 651/652/653: HH objects are bright patches of nebulosity associated with newborn stars located at RA/DEC: 20h58m17s / +43°53'40". They are formed when narrow jets of partially ionised gas ejected by stars collide with nearby clouds of gas and dust at several hundred kilometres per second according to NASA Hubble Mission Team.
