Nombre: Nebulosa Cabeza de Mono
Tipo: Cúmulo estelar abierto con nebulosas de extensa emisión asociadas
Designación: NGC 2175, Cr84, OCL476, IC2159
Constelación: Orion (Orión)
Ascensión Recta (J2000): 06h 09m 39s
Declinación (J2000): +20º 29' 15''
Distancia a la Tierra: 6350 años-luz

NGC 2175 es un bonito cúmulo estelar abierto que se halla inmerso en una extensa nebulosa de emisión HII. Ha habido discrepancia desde hace años, ya que también ha sido referido con el nombre NGC 2174. Ambas identificaciones hacen referencia principalmente a la nebulosa, que forma parte de una región más extensa, una región HII denominada Sharpless Sh2-252.
El cúmulo parece corresponder a Collinder Cr84, si bien no hay fuentes muy claras al respecto. Está formado por estrellas jóvenes, predominando aquéllas de tipo espectral O. En el centro hay una que destaca levemente, que parece ser la causante de ionizar a la nebulosa. Unas 70 estrellas se dispersan por toda la zona sin una estructura aparente.
El cúmulo fue descubierto por Giovanni Batista Hodierna antes de 1654 y posteriormente redescubierto independientemente por Karl Christian Bruhns en 1857.
La nebulosa se conoce comúnmente con el nombre de “Nebulosa Cabeza de Mono” por su forma característica que recuerda la cabeza de ese animal. El gas brillante y el polvo oscuro no sobreviven bien en la Nebulosa Cabeza de Mono. Las estrellas jóvenes cerca del centro de la nebulosa generan vientos estelares y radiación de alta energía que hace que el material de la nebulosa adopte formas complejas. La nebulosa está compuesta principalmente de hidrógeno alfa HII ionizado que brilla en longitudes de onda infrarrojas debido a la radiación.
Este cúmulo estelar es fácilmente localizable entre la mano derecha levantada de Orión y el pie de Géminis, en una zona muy rica de la Vía Láctea invernal, pero se necesitan telescopios reflectores de grandes aberturas superiores a los 200mm para poder vislumbrar la nebulosa. Un filtro UHC ayuda a mejorar la observación visual de la nebulosa. Fotográficamente, el cúmulo y su nebulosa son fácilmente registrables con teleobjetivos luminosos de f/4 e inferior y tiempos de exposición de pocos minutos.

Looking for more obscure objects again. This is a young star forming region, contains masers too. Very close to the Bubble Nebula but just across the constellation boundary in Cepheus, in the Perseus arm of the Milky Way. It contains the largest known protostar (NGC 7538S) discovered to date with a diameter of the order of 300x the size of our solar system.

This is the first colour image taken through the rebuilt double truss newt - a tough subject for starters! The diffraction around Merope (and from Alcyone top left) make it a little distracting across the front of the nebula! The three dark regions at 60 degrees are from the mirror clips, the additional one to the right is a slight protrusion of the drawtube into the light path.
The image could do with more exposure, and no flats have been taken, which should also improve the image somewhat. But, this was a test in getting off axis guiding working (good! RMS was about 1.4px on the ASI120MM guider). FWHM measured at 3.3arcsec for the stack, but the quality of the frames deteriorated during the session - possibly indicating I needed to refocus...

About 12-13 million years old and about 7,500 light years from earth. Clusters NGC 869 and NGC 884 can be scene with the naked eye from a dark sky site and with cheap binoculars elsewhere, just use the second line in the W of Cassiopeia to point to the left, it will appear as 2 faint smudges. Also known as Caldwell 14.
According to Wikipedia these clusters are blue shifted which means we are getting closer to them.
There are a good variety of star colours in this region, hopefully I have processed it OK to demonstrate this.
183x30s (about 1.5 hours) with flats and bias. Dithered every 4 frames. Taken 20/12/2020.

Processing Software: Stacked in Deep Sky Stacker, edited in Star Tools.
Moon: 38% Waxing Crescent
Light Pollution and Location: - Bortle 7/8 in Davyhulme, Manchester. Different websites tell me different things about this. It all depends on the time of night and which way I am pointing. At this time of year, with all the Christmas lights it is pushing 8 and above.
Weather: - A good clear spell of about 5-6 hours, as always at this time of year things start to get damp relatively quickly. Still low pressure, we have not had a run of high pressure since September.
Notes: - I was having problems with my
cheap laptop, the connection to the Wi-Fi SD card kept cutting out and its slow, especially at plate solving. I have relatively good PC with usb3 port, lots of RAM and solid-state drive so I have decided to make the switch to that. To do this I have had to buy a 20-meter usb3 extender cable.
First light with new PC was 12th December, this was the first moonless clear night for months. To say I was underprepared was an understatement. I spent several hours installing the required software to get things going and had forgotten how much work was involved in this. Eventually I got everything going apart from the guide camera which needed a major Windows update that I did the following day. To add to my problems the piece of metal on my mount that works with the azimuth screws to go left and right was loose. Stupidly I ignored this and ploughed on, polar alignment was tough, in SharpCap it would just jump about from one extreme to the other. I also still had my light pollution filter out. It was not a successful night, I had eggy starts and unworkable gradients. Too much of an effort to fix in star tools. I have since made sure this metal bit is connected properly.
So, on the 20th December I was much more prepared. Having marvelled at the great conjunction from my loft I set about working, this time with guiding and with the light pollution filter. (I know most people would have been working on the planets, but I do not have the right view to able to get it, too many houses and trees are in the way; sometimes I am happy enough with my eyes and cheap bino’s)
Polar alignment worked much better; the error was less than 1” so that makes me happy! The plate solving was amazing, its instantaneous which is great. The Wi-Fi connection to the SD card remained and it seems to transfer the files a bit quicker too. The Wi-Fi/SD combination is still not perfect as there is a 20s wait between subs, but at least it works.
Going forward I am reverting to 400 ISO and perhaps 1-minute subs. I am still convinced by Robin Glovers lecture but the D3100 is so noisy, the jump from 400 to 800 seems too much. I would love to know the read noise calculations for this camera so I could be more precise with my exposure times. One day it will be side lined for a better camera.
On a personal note, in January, I should become a Dad for the first time, this should be fantastic but will probably mean less time for this hobby. Let us see what happens!
