I had a few hours of semi clear sky and thought I would try and image NGC281, I was hoping to image until 00:30, but clouds rolled around 23:50 so I decided to call it a night.   But the amount of time I had and the quality of the sky in my neighboorhood,  I think the image turned out ok.  I first tested using my Optolong L-Pro filter and then followup with either the L-eNhance or L-Ultimate, but L-Pro the image was too faint so I am glad I decided to use the L-Ultimate given the time I had to image.  I am not sure if I want to adjust the image further, but I might give it a go in PixInsight.

The image also contains the Stars, Schedar and Achird:

Alpha Cassiopeiae or α Cassiopeiae, also named Schedar(/ˈʃɛdɑːr/), is a second-magnitude star in the northern constellation of Cassiopeia.
α Cassiopeiae is thought to be around 100 to 200 million years old, having spent much of its time as a blue-white B-type main-sequence star.


Eta Cassiopeiae (η Cassiopeiae, abbreviated Eta Cas, η Cas) or Achird is a binary star system in the northernconstellation of Cassiopeia. Its binary nature was first discovered by William Herschel in August 1779. Based upon parallax measurements, the distance to this system is 19.42 light-years (5.95 parsecs)from the Sun. The two components are designated Eta Cassiopeiae A (officially named Achird/ˈeɪtʃərd/, the traditional name for the system) and B.The proper name Achird was apparently first applied to Eta Cassiopeiae in the Skalnate Pleso Atlas of the Heavenspublished in 1950, but is not known prior to that.

NGC 281 - Pacman NebulaNGC 281 is an H II region in the constellation Cassiopeia, nicknamed the "Pacman Nebula" for its resemblance to the video game character. NGC 281 was discovered in August 1883 by E. E. Barnard, who described it as "a large faint nebula, very diffuse."The nebula is visible in amateur telescopes from dark sky locations. With an O-III filter, NGC 281 appears fairly bright, large, and irregular. Several dozen stars are concentrated at its center. The nebula is crescent-shaped, with dark lanes dividing it on the north side. The brightest nebulosity, on the NW side of the object, is about 15' across, with an obvious multiple star at its luminous center. Other patches of nebulosity are visible to the SE.The multiple star, HD 5005, was discovered by S. W. Burnham. It consists of an 8th-magnitude primary, with four companions at distances between 1.4" and 15.7". There has been no appreciable change in this quintuple system since the first measurements were made in 1875.The Pacman nebula lies about 10,000 light years distant, in the Perseus spiral arm of our galaxy. It is a busy workshop of star formation. Prominent features, besides its diffusely glowing hydrogen gas, include dark lanes of obscuring dust and dense knots of gas and dust - Bok Globules - in which stars may currently be forming. NGC 281 also includes the open cluster IC 1590, of which the multiple star HD 5005 is the brightest member. Its light helps ionize the nebula's gas, causing the red glow visible throughout.

NGC 281, IC 11 or Sh2-184 is a bright emission nebula and part of an H II region in the northern constellation of Cassiopeia and is part of the Milky Way's Perseus Spiral Arm. This 20×30 arcmin sized nebulosity is also associated with open clusterIC 1590, several Bok globules and the multiple star, B 1. It collectively forms Sh2-184,[3] spanning over a larger area of 40 arcmin.[4] A recent distance from radio parallaxes of water masers at 22 GHz made during 2014 is estimated it lies 2.82±0.20 kpc. (9200 ly.) from us.[5] Colloquially, NGC 281 is also known as the Pacman Nebula for its resemblance to the video game character.Edward Emerson Barnard discovered the nebula in August 1883, describing it as "a large faint nebula, very diffuse". Multiple star 'B 1' or β 1 was later discovered by S. W. Burnham, whose bright component is identified as the highly luminous O6 spectral class star, HD 5005 or HIP 4121. It consists of an 8th-magnitude primary with four companions at distances between 1.4 and 15.7 arcsec. There has been no appreciable change in this quintuple system since the first measures were made in 1875.The nebula region is visible in amateur telescopes from dark sky locations. In his book Deep Sky Wonders, Walter Scott Houston describes the appearance of the nebula in small telescopes:[6]"There was a faint glow in the immediate vicinity of the multiple star, with an occasional impression of a much larger nebulosity...Its surface brightness was much less than that of M33 in Triangulum or NGC 205, the distant companion of the Andromeda galaxy."
