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 Momoceros region of the Milky way galaxy. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter
The cluster and nebula lie at a distance of some 5,000 light yeads 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.

Qualche sera fa ho provato a fotografare con il telescopio (e dalla città) la galassia M51, chiamata anche Galassia Vortice. In realtà si tratta di una meravigliosa coppia di galassie interagenti che si stanno scontrando a una distanza di decine di milioni di anni luce da noi.
Come sempre, fotografare l'universo dalla città è sempre una impresa difficile, ma grazie alla tecnologia, ad una corretta attrezzatura, un po' di soldini e tanta pazienza, si può pensare sempre più in là.

I took this close-up with a Sky-watcher Skymax 102, ZWO ASI 120MC-S and a Star Adventurer Pro by taking a short video, and then using only the best frames to stack. :)
I decided to go ahead and name most of the lunar features visible in the picture. ;)
Software used: Firecapture, PIPP, Autostakkert, Registax and Photoshop (for the names)
another dark nebula i tried my best on, seems to be a very faint one as 6h of exposure made it only that visible. though the nights are still getting shorter and shorter for 5 more weeks, maybe i spend one or two extra nights on it.

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!

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.

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.
Imaged with a Skywatcher Esprit 120ED Triplet Apo and a ZWO 2600MC camera.

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.
