This was a project almost 4 months in the making. I spent over the course of 24 separate short late spring/summer nights capturing subs on this, most challenging target. Starting May 8, then every clear night until August 19, after discarding several hours (over 11 hours) of sub standard frames I ended up with just over 53 hours of usable data. Ever since I saw a picture of the object I wanted to capture it myself. but I had no idea the frustration that would ensue! I worked for hours/days on putting the final image together to something I was proud of. I have seen so many gorgeous renditions of this object and I wanted to give it justice as well. I went with a more natural approach to the final version. OU4 is an extremely faint "nebula" I wanted to make sure that it was visible in the final version, but also maintain the appearance of being very faint and natural looking. I did not want to "over cook" OU4.
The oxygen portion of the image was taken with 37 hours of total integration time. It was still very difficult to isolate OU4 from the background even with that amount of time. I went through countless iterations of workflow to bring it out and make it look authentic. The Chroma 3nm filter did a great job of isolating the signal, it is just so faint, maybe 30min subs instead of 20 min subs would have made a difference?
I have done some minor star reduction, but Cepheus is a very dense star field so I wanted to keep them there, just not distracting, to keep the natural feel of the image. Did I succeed?
I have searched for what I perceive as everywhere on the internet for data on OU4 regarding the apparent magnitude of the object. If anyone has this info please let me know.
Overall I am very happy with the way this image has turned out, don't know if I will ever tackle it again as it takes up a lot of clear skies at a time of the year when the dark nights are very short. I would love to hear your feedback and suggestions for the future.
Thank you and clear skies
Dan.
Nearby spiral galaxy NGC 4945 in the constellation Centaurus by Mike O'Day ( 500px.com/MikeODay )..NGC 4945 in the constellation Centaurus is a large spiral galaxy about the size of the Milkyway and around 13 million light years from Earth.

It's possible only the tiny 2822 spot.
As I still have the small Rig I went with a suggestion from Carlos, train it on the LMC. This was a good Idea but for the facts it's not in the best position. 1 AM the trees sneak into the shot. Add to this the time of year as clouds increase and rain starts so harder to buy clear nights.
The great part there is a lot of targets out there to shoot. This was a two shot panorama of the area.

I've always struggled with this target. I use an old Canon 1100D unmodified camera and really struggle to get the fainter parts of the spiral arms.
This image was done with a Skywatcher 8" quattro with f4 aplanatic coma corrector on a HEQ5 pro mount.
Guiding was with an Altair 50mm guide scope and an Altair GPcam1 AR0130c
I used an unmodded Canon 1100D with an Astronomik clip in ccd filter and a Neewer intervalometer.
Software used was DeepSkyStacker, StarTools & Gimp.

The Lagoon Nebula (M8), is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula.
This image was taken the same night as the previous comet and was first light for my new camera, the ASI585MC-Air, an all in one camera, computer and off-axis guider. I was extremely impressed at how everything worked, and how quickly I was able to adapt it to my setup.

The Rosette Nebula (also known as Caldwell 49) is a large spherical H II region (circular in appearance) located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy.
The cluster and nebula lie at a distance of some 5,000 light-years from Earth) and measure roughly 130 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses. (Wikipedia)

Nebulosa Trífida o Messier 20
Aquí comparto otra foto tomada este verano.
Se trata de la nebulosa trífida, o messier 20.
La capturé con el Newton 1000mm f5, y la ASI294MC, el filtro L-Enhace y la montura EXOS2 PMC8.
Me faltó exposición, quizá el verano próximo le tire alguna noche más.
Espero que os guste.

Clear skies during the night of the 15th to 16th April allowed me to image the beautiful Needle Galaxy NGC 4565 in Coma Berenices.
This edge-on spiral galaxy is located between 30 and 50 million light-years from us. The galaxy's bright core of stars bulges out on each side of the comparatively thin galactic disk with its prominent dust lanes. The effect is somewhat akin to the analogy of two fried eggs laid back to back!
I have tried to name some of the fainter systems within the wide view. One of these NGC4562 is about 75 million light-years from us. A dwarf galaxy IC3571 is also visible near the Needle Galaxy.
Imaged with a Skywatcher Esprit 120ED and a ZWO 2600MC camera.

Single shot - tracked on Skywatcher Staradventurer. The chilean sky of the Atacama desert is just magical. 30s exposure are enough to reveal beautiful deep sky nebulae such as the Lagoon (M8) and the Trifid (M20).

A night of 01 - 2nd April allowed me to image M106 in Canes Venatici which is near the handle of the Plough or Big Dipper.
The galaxy itself is over 20 million light-years distant and is around 80,000 light-years across.
The galaxy was discovered by Pierre Méchain in 1781, with Charles Messier including it in his famous catalogue as M106.
M106 contains an active nucleus and is classified as a Type 2 Seyfert. Radio wavelength observations have indirectly confirmed the presence of a massive black hole at its centre.
Prominent at the bottom frame is galaxy NGC 4217 with a strong, dark, dust lane. This galaxy may be a companion of M106.
