Also see the previous version, which was proceeded to more clearly highlight the elements of Hydrogen and Sulfur at the red end of the Spectrum, and the doubly ionized Oxygen at the blue end of the Electromagnetic Spectrum of Light. Rosette Nebula in Narrowband.
About this image:
A Hydrogen-Alpha + Sulfur-II + Oxygen-III Narrowband image of the Rosette Nebula (also known as NGC 2237 or Caldwell 49).
The Rosette Nebula is a large, spherical H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, as the stars formed from the nebula's matter.
The cluster and nebula are at a distance of 5,000 light-years from Earth and measure roughly 50 light-years in diameter. The radiation from the young stars excite the atoms in the nebula, causing it to emit radiation (producing the emission of the nebula at specific spectral lines that we can image).

*Nebulosa Iris y fantasmas en Cefeo.*
La nebulosa Iris, a la izquiera, también conocida como NGC 7023 y Caldwell 4, es una nebulosa de reflexión azul brillante en la constelación de Cefeo. NGC 7023 es en realidad el grupo de estrellas dentro de la nebulosa LBN 487.
A la derecha se pueden observar unas nubes moleculares de polvo intelestelar con curiosas formas fantasmagóricas, la inferior, mas brillante, es conocida cómo el fantasma de la antorcha, vdB 141 o Sh2-136.
La nebulosa iris se encuentra a 1.300 años luz y los fantasmas a 1.200 años luz, con un tamaño de unos 2 años luz aproximadamente.

The M51 galaxy, 31 million light-years away from Earth, is a spiral galaxy visible to the inside of the hunting dog constellation. Recompile a photo made in March, but with the difference that this time I used the Drizzle algorithm that doubles the size of the photo. Although the total exposure time is poor (only 11.5 hours of laying), some emission nebulae are also noticed. Setup used: Newton Sw 200/1000 with Mpcc 3 mounted on a Neq6 Pro frame, sum of 139 poses from 5 minutes to 200 iso made with a Canon 1100d full spectrum reflex
Bodes Galaxy is a grand design spiral galaxy about 12 million light years away. The Cigar Galaxy is thought to have at some point interacted with Bodes Galaxy, taking lots of dust and causing it to be become a starburst galaxy where stars are being born 10 times faster than the milky way.

Seeing: - Good
Notes: - I have got to the point where I can just set up and get going. This has taken me a long time to get to. I did take pictures for 2 nights but in the end only kept the second nights work. I may at some point come up with a successful re-process with both days data. In the end I felt 5 hours is enough for this setup although I have read somewhere that this object benefits from as much data as possible.
I think the flats on the first night and prior shots I’ve taken had too much exposure. I still think I am overexposing these as I am getting rings in my pictures. I’ll go even lower on the next object.

Light Pollution and Location: - Bortle 8 in Davyhulme, Manchester.
Seeing: - Good
Notes: - Having set up for about 9pm it was still very much daytime; the north star finally appear at about 10pm but it was getting on 10.30 before I could do the SharpCap polar alignment. According to the FLO clear skies app, it was the first night with just twilight and no night. I had to do some weeding while waiting to get going. Also, it went down below 0 which is crazy for the middle of May. I am glad I a dithering these days and not relying on darks with the major shifts in temperature.
How I will get on as the days get even longer will be interesting. It must take a week to get any decent exposure time.
Ha+OIII Bi-Color Narrowband image of the Cygnus Wall. The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus, close to the star Deneb. The remarkable shape of the nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico.
The Cygnus Wall:
The Cygnus Wall is a term for the "Mexico and Central America part" of the North America Nebula. The Cygnus Wall has the most concentrated star formation in the nebula. The North America Nebula and the nearby Pelican Nebula, (IC 5070) are in fact parts of the same interstellar cloud of ionized hydrogen (H II region). The nebula complex is estimated to be about 1,800 light-years from Earth.

A H II region of space. A H II region or HII region is a region of interstellar atomic hydrogen that is ionized. It is typically a cloud of partially ionized gas in which star formation has recently taken place. The Pelican is much studied because it has a particularly active mix of star formation and evolving gas clouds. The light from young energetic stars is slowly transforming cold gas to hot and causing an ionization front gradually to advance outward. (Wikipedia)

Seeing: - A mixture of average and good nights.
Notes: - Processing threw a new curve-ball at me for this picture. Not only is the nebula taking up the whole frame, but there was a line going through it. After a bit of forum help and a reprocess I have tried to remove it. Apparently it was caused by a reflection of something out of frame; as it pointed directly at Deneb, this is the likely candidate. The Star Tools Heal module did an OK job. This is a reprocess of the original I uploaded getting rid of a lot of noise and green although both is still present.
It’s been hot in Manchester for a little while now. Its nice to have a good few nights of work to do even if I don’t get many subs per night.
I managed to get a lead and adapter that will connect the mount to the shutter release in the D3100 so I feel my road to automation is getting closer. I tried to get NINA to work which successfully opened and closed the shutter once but then it seemed to want to find a picture file. Unfortunately it doesn’t seem to let me do that on the D3100. I’ve done some research and ordered a wifi sd card which I believe will give NINA somewhere to look. I just have to wait a month and a half until delivery date!

About 23 thousand light years away and 145 light years in diameter comprising of several hundred thousand stars. Most of these stars are incredibly old, about 12 to 13 billion years. Sometimes, as they are so densely packed together, they collide and make new ‘blue straggler’ stars. I can imagine living on a planet around one of these stars, you must not be able to see beyond the local cluster. (Wikipedia and Earthsky)

Seeing: - Goodish
Notes: - Much as I have enjoyed taking galaxies I really wanted to try something different so had another go at the M13. I did some reading on this beforehand and a lot of people say they don’t overexpose as the core gets blown up. For this reason I took several 30s, 60s, 150s and 300s subs. In the end, the Star Tools Decon module did a really good job of bringing out detail in the core even with my 5 minute exposures so I have just abandoned my shorter ones.
Colour is a constant problem for me with my red/green colour blindness so I rely on the Max RGB option in Star Tools and my wife although I didn’t bother her in this process. In this case I cranked up the ‘Cap Green’ option, and took a sample of the core/nearby galaxy so I hope this is close to being right.
The amount of noise in this picture is annoying me. Another go may be required at some point, either to reprocess or to take the picture when its closer to the zenith.
Previous attempt for comparison:- www.flickr.com/photos/andrewsingleton/8721642768. 7 years ago and some new equipment has made a remarkable improvement on this old picture. This was my first ever attempt at astrophotography through a telescope.

Difficult to bring out the dust. Poor guiding resulting in a few "rugby ball" stars - <0.7" but often in just one direction. Light pollution from the Forth Bridges really spoiled this image. Too much going straight up into the sky, directly beneath this object. Shameful waste of electricity and destruction of the night sky.

The Andromeda Galaxy, along with M32 and M110, two dwarf galaxies orbiting M31.
Had a good time with @JR Manuel in the middle of nowhere, I imaged M31 while he took shots of the beautiful Milky Way.
With an 8" telescope, this is not the best target, due to its size / distance, the Andromeda galaxy is not completely in the frame. It also makes the editing pretty vicious because of the lack of space / black around the gases of the galaxy.
Called The Great Andromeda Nebula until his galactic nature was recognized in the 1920s, the spiral Andromeda Galaxy is the closest galaxy from the Milky Way, and the largest one in our Local Group. With an apparent diameter of about 140,000 light years, it is believed to contain about a thousand billion stars.
The Andromeda Galaxy is one of the few galaxies visible to the naked eye from Earth in the northern hemisphere. It is also one of the biggest objects in the sky, with an apparent diameter of more than six times that of the Moon.

The North America Nebula:
The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus, close to the star Deneb. The remarkable shape of the nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico.
The Cygnus Wall:
The Cygnus Wall is a term for the "Mexico and Central America part" of the North America Nebula. The Cygnus Wall has the most concentrated star formation in the nebula. The North America Nebula and the nearby Pelican Nebula (IC 5070), are in fact part of the same interstellar cloud of ionized hydrogen (H II region). The nebula complex is estimated to be about 1,800 light-years from Earth.

A planetary nebula with a diameter of 1 ly and about 200 ly away (Wiki says 2800 but parallax says 15.7mas ~200ly). Another William Herschel discovery. You can see the central star is still quite bright but is now a cooler white dwarf. There’s a nice double star system just top right of the nebula, although I suspect from their parallaxes (2.13 mas and 1.97 mas) it’s not a binary system. The nebula is much closer with a parallax of 15.7 so not associated with the double star.

The Southern Pinwheel Galaxy ( Messier 83, NGC 5236 ) in the constellation Hydra - by Mike O'Day ( 500px.com/mikeoday )..Messier 83 is a relatively large and bright spiral galaxy visible from southern and mid latitudes. Clearly visible is the central bar with its bright central bulge as well as multiple dark dust lanes and areas of nebulosity in the sweeping arms. At a distance of 15 Million light years, the Southern Pinwheel Galaxy, whilst close in astronomical terms, is too far away and hence way too small for my backyard telescope to resolve individual star; so all of the stars that can be seen are in fact in the near foreground of the image and reside, like us, in the Milkyway Galaxy...Much harder to see are the multitudes of far more distant galaxies that look like tiny fuzzy stars in the image. The easiest of which are PGC 724536 and PGC 48132 that appear close together in the centre of the image just to the right of Messier 83. Both are edge on and look like tiny flying saucers...Details:..Skywatcher Quattro 10" f4 Newtonian. .Skywatcher AZ Eq6 GT Mount .Orion 80mm f5 guide scope and auto guider - PHD2. .Nikon D5300 (unmodified)...Hutech IDAS D1 filter, 14bit NEF, Long Exp.

The Western Veil (NGC 6960) aka The Witch's Broom, Finger of God, Lacework Nebula or Filamentary Nebula. This is part of the Cygnus Loop which is a supernova remnant. The source supernova was a star 20 times more massive than the Sun, and it exploded between 10,000 and 20,000 years ago. The remnants have since expanded to cover an area of the sky roughly 3 degrees in diameter (about 6 times the diameter, and 36 times the area, of the full Moon). While previous distance estimates have ranged from 1200 to 5800 light-years, a recent determination of 2400 light-years is based on direct astrometric measurements. The Veil Nebula is expanding at a velocity of about 1.5 million kilometers per hour. (Wikipedia)

Notes: Its been a massive learning curve but I have finally got NINA astrophotography to work controlling pretty much everything. I am extremely impressed with this software. Furthermore my trusty old D3100 shutter was controlled by the software through the mount and using the file camera it was able to pick up the pictures just like connecting more expensive Nikons or Cannons to APT(or several other apps that I looked into but came to dead end with the D3100). I was able to bring up the schedule, load the Western Veil which was currently focused on in Stellarium, set the amount of subs I wanted, turn on dithering, then NINA just did its thing by attempting to find the object then correcting itself through plate solving. It even did a meridian flip and recentred the object afterwards. Watching it do its thing was a thing of beauty and is miles away from my original attempts at astrophotography using a AZ goto mount and a star chart.
Being completely up front, like everything in astrophotography you must take several steps backwards before taking a step forward. I have dabbled with NINA for a while but struggled to get to grips with it. I tried taking this same object a few weeks ago but did not have a good session. For some reason, the plate solving was not accurate enough and the object was only half was in frame. This is either because I hadn’t loaded my coordinates in PS2 or the file camera was picking the last picture instead of the current one. Looking back 52 Cygni is very bright star front and centre and it should have been obvious to me that something was not right.
Incidentally that same night, about 4-5 subs in my pictures suffered from dew, pretty much writing them off. I have since bought a cheap camping mat and Velcro to make a home-made dew shield. Handily the camping mat camp with a perfectly sized bit of elastic; I have cut up some cheap cycling shorts and used the elastic to block out any light from the bottom of the telescope. I am hoping this will also help with the dew. I have also made a dew shield for the guider.
I took a gamble on this picture as the weather forecast had me believe that it was going to be cloudy all night. Up until this session it had been predicting a clear night all week and it looked relatively clear when I looked out of the window before setting up. It then cloudy over but only for about an hour and a half which gave me time to make sure everything was set up properly. It then became clear, although seeing was bad, but this did improve over the course of the night. Thankfully, my gamble paid off and is point back in the battle between me and the weather, I have been done so many times with the forecast predicting clear skies but them not materialising.
I add this comment to the end of every one of my pictures but the amount of green being picked up in the Star Tools colour module is insane. I think the D3100 bayer filter is 2 green to every red and blue, it seems like its 10 greens to every red and blue. I hope the colour in this is OK however I had to bump the green bias correction right up and max out the cap green slider. I am slowly but surely saving up for a proper cooled camera which am sure will again take me several steps back before bringing me forward!
