Rosette Nebula in Monoceros ( NGC 2237, 2238, 2239, 2244, 2246 ) by Mike O'Day ( 500px.com/MikeODay )..The Rosette Nebula surrounds a cluster of bright young stars (NGC 2244) and is around 5,200 light years from Earth. The bright red colours usually associated with the nebula are not as visible hear due to the filter in the unmodified Nikon DSLR used to capture the image. ..Links:..https://500px.com/MikeODay.http://photo.net/photos/MikeODay..Details:..This image ~ RA 6h 31m, Dec 5deg 2'. .Skywatcher Quattro 10" f4 Newtonian. .Skywatcher AZ Eq6 GT Mount..Orion Short Tube 80mm guide scope & auto guider - PHD2. .Baader MPCC Mark 3 Coma Corrector (no filter used)..Nikon D5300 (unmodified)..Field of view (deg) ~ 1.35 x 0.90..71 x 30 sec ISO 800...Pixinsight & Photoshop.20 December 2015

I tried something different with this because of the really bright stars and the horrible micro lensing of the 1600MM. I used 20 second exposure and tried to capture as many as I could until M45 set to low for me to continue imaging. I ended up with 560 sub frames. I was hoping I could avoid 1600MM issues and still get a decent amount of nebulosity in the image.
This took me 14 iterations of processing to arrive at an image I was somewhat happy with. Trying to balance the bright stars with the dust was a challenge.
Overall I am happy with the image with only 3hrs integration. I really want to fully capture the full extent and detail of the dust and the deep saturation of the reflection elements. I could get more deeper saturation with more integration time and with different sub lengths for a HDR processed image, maybe next year!

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

M33 Triangulum galaxy
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 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.
