Red hydrogen emission and blue reflection nebulae, dark molecular clouds and a bright star sitting in the middle, flooding the scene its yellow light... Sounds like the Rho Ophichui region?
Sure. There is, however, another smaller, but similarly colorful area in the sky:
Meet the Cave Nebula!
Officially designated Sh2-155, the Cave Nebula in the constellation Cepheus, is a diffuse nebula of ionized hydrogen with ongoing star formation activity, at an estimated distance of 2400 light-years from Earth. It lies within a larger complex containing emission, reflection, and dark nebulosity.
The name "Cave Nebula" for Sh2-155 was coined by Patrick Moore, presumably derived from photographic images showing a curved arc of emission nebulosity corresponding to a cave mouth. Earlier, the name was already used to refer to another brighter but unrelated reflection nebula in Cepheus, known as Ced 201. The name's application to Sh2-155 has come into vogue through the nebula's inclusion in Moore's Caldwell catalogue as object Caldwell 9.

NGC 7293 a.k.a. Helix Nebula
…………………………..
Helix Nebula, also known as the Eye of God, is a planetary nebula that was discovered about 200 years ago by German astronomer Karl Harding and can be found at 650 light-years from Earth, in the constellation of Aquarius. Specialists believe that Helix appeared due to a star relatively similar to the Sun, a star that reached the last stage of its existence and began to release large amounts of energy and gas in the outer space. The calculated diameter of this nebula is almost 3 light years, and the expansion speed exceeds 20 miles / sec.
In the northern hemisphere ( 45 degrees ) Helix can be observed / imaged only during the summer, August being the best month for this, but because it does not rise much in the night sky, those passionate about astrophotography and / or visual observations must use locations with a good opening towards the south, and away from the light pollution of the big cities.

I had only recently purchased some narrow-band filters and was keen to give them a test run; for this, I chose NGC281. The aim was initially to capture data in LRGB along with Ha, OIII, and SII; the telescope and weather had other plans. I hadn’t looked at the data since the initial night, and using a process in Pixinsight inspired by Cuiv’s recent mastering Pixinsight YouTube video, I was able to bring together this HOO image of the nebula; it is a target that I plan to revisit this winter to capture more Ha and OIII, along with LRGB and SII data.
NGC 281, IC 11 or Sh2-184 is a bright emission nebula and part of an HII region in the northern constellation of Cassiopeia and is part of the Milky Way’s Perseus arm. This 20×30 -sized nebulosity is also associated with open cluster IC 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 22Ghz in 2014 is estimated to be 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. Source: Wikipedia

Reasonably clear skies on the night of 19-20 March allowed me to try to image NGC 2403 in the constellation of Camelopardalis.
This is my first attempt at imaging this system.
The galaxy lies at a distance of around 8-9 million light-years from us. The galaxy was discovered by William Herschel in 1788 and is an intermediate spiral system.
The galaxy bears a striking resemblance to its more illustrious colleague, M33 The Triangulum Galaxy, having the same somewhat flocculated appearance but also a plethora of pinkish-reddish star forming HII regions.
The galaxy is considerably larger than M33 making it one of the largest HII regions observable.

Another RE Edit of some old data from July 2021 . Carina nebula or Eta Carinae Nebula . Shot with Canon 5Dsr on a Skywatcher Quattro 250P Telescope. 15 x 55 second exposures stacked with Calibration frames .

Have not been very well lately and unfortunately it is ongoing. So haven't been about.
I did managed to get some imaging done this month (weather has been hopeless as usual - so not helping!)
This is an image of the emission nebula, "The Great Orion Nebula" M42, with the attendant reflection nebula "The Running Man" Sharpless Sh2-279 to the right. Both these beautiful systems are found in the sword area of the magnificent constellation of Orion.
M42 is one of the brightest nebula in our skies, lying at a distance of over 1300 light years. This massive cloud of glowing gas and dust is a stellar nursery and is the closest massive star forming region to earth.
The Running Man Nebula to the right is so-called because many observers liken its appearance to a human running with arms flailing! (you might need to use a bit of imagination!) This is a reflection nebula. This means it is only visible to us because light from an illumination source, such as embedded stars, lights up the surrounding gas and dust.
Extensive dust clouds can be seen throughout the whole image.
Imaged with a Skywatcher Esprit 120ED refractor fitted with a focal reducer (scope at f5.4) and a ZWO 2600MC camera.

Messier 104 a.k.a. Sombrero Galaxy
…………………………..
Discovered 250 years ago, the Sombrero galaxy (The Hat) is an elliptical galaxy located just over 30 million light-years from us and can be seen between the constellation Virgo and the constellation Corvus. According to measurements made by specialists in the field, M104 has a diameter of about 40,000 light-years, being about 3 times smaller than our galaxy. The name of the Hat is given both by the angle from which we can see it, and due to that prominent ring of cosmic dust that surrounds this galaxy and which is also the main source of new star formation. Regarding the nucleus of this galaxy, with the help of special infrared measurements it was found that in the galactic center of M104 there is a massive black hole, larger than in any other galaxy located within a radius of 40 million light years around the Milky Way.

The Eastern Veil nebula is a cloud of heated and ionized gas and dust in the constellation of Cygnus, located at around 1470 light-years from Earth. It is part of the Cygnus Loop which is a 7000 years old, faint supernova remnant, covering roughly 3° on the sky (almost 6 full moons). The red hues in this image are from ionized hydrogen gas clouds, emitting light in the H-alpha wavelength, while the cyan hues are from oxygen ions.
