Description

Glorious clear skies last night in the UK

Near full moon though so went duo narrow band using the Redcat 51

Guiding wasn't brilliant 1.05" error by at very short focal length stars appear round

Have discovered PHD2 log viewer so can see the full horror of my backlash

Got two hours forty five minutes, binned the last fifteen minutes as sky bright ... run finished just before 4am

Not gone heavy on processing ... will undoubtedly do various versions of this

Did an hour and a half on M13 before this, will post that at some point

Note - my youngest son has gone totally nocturnal through the lockdown and woke me at 2:30 shouting "Dad there is a man outside the house" over and over ... I thought some one was trying to steal my scope1 it was in fact ... the milkman lol

Wiki tells

The North America Nebula is large, covering an area of more than four times the size of the full moon; but its surface brightness is low, so normally it cannot be seen with the unaided eye. Binoculars and telescopes with large fields of view (approximately 3°) will show it as a foggy patch of light under sufficiently dark skies. However, using a UHC filter, which filters out some unwanted wavelengths of light, it can be seen without magnification under dark skies. Its prominent shape and especially its reddish color (from the hydrogen Hα emission line) show up only in photographs of the area.

The portion of the nebula resembling Mexico and Central America is known as the Cygnus Wall. This region exhibits the most concentrated star formation.

The North America Nebula and the nearby Pelican Nebula (IC 5070) are parts of the same interstellar cloud of ionized hydrogen (H II region). Between the Earth and the nebula complex lies a band of interstellar dust that absorbs the light of stars and nebulae behind it, and thereby determines the shape as we see it. The distance of the nebula complex is not precisely known, nor is the star responsible for ionizing the hydrogen so that it emits light. If the star inducing the ionization is Deneb, as some sources say, the nebula complex would be about 1,800 light-years' distance, and its absolute size (6° apparent diameter on the sky) would be 100 light-years.

The nebula was discovered by William Herschel, from Slough, England, on October 24, 1786 or by his son John Herschel before 1833.[4]
