M3 was the first Messier object to be discovered by Charles Messier himself. Messier originally mistook the object for a nebula without stars.
M3 contains over 500,000 stars and the most variable stars within a single cluster.
It is 33,000 light years distant and is about 10 billion years old.

The Owl and the Galaxy. Small Targets in a Small Telescope
The Owl Nebula (also known as Messier 97, M97 or NGC 3587) is a planetary nebula located approximately 2,030 light years away in the constellation Ursa Major.
Messier 108 (also known as NGC 3556) is a barred spiral galaxy in the constellation Ursa Major. It was discovered by Pierre Méchain in 1781 or 1782. From the perspective of the Earth, this galaxy is seen almost edge-on. (Wikipedia.org)
The galaxy is approximately 32 million light years from Earth.

NGC 5985, NGC 5982 and NGC 5981 are three galaxies in the constellation Draco, collectively known as Draco Triplet. This triplet is less known than Leo Triplet and unlike it, most probably these three galaxies are not interacting with each other. These are part of a larger group of galaxies known as the NGC 5982 Cluster.
This is my second attempt to photograph this region and I think with improved results (mileage and sark skies always help...)
I hope you enjoy and I'd love to hear your feedback on it.
Cheers,

This is the first record I make of the "Helm of Thor" nebula (NGC 2359). The stacked frames, captured in four nights, totaled 10 hours and 30 minutes of exposure.
"NGC 2359 is a helmet-shaped cosmic cloud with wing-like appendages popularly called Thor's Helmet. Heroically sized even for a Norse god, Thor's Helmet is about 30 light-years across. In fact, the helmet is more like an interstellar bubble, blown as a fast wind from the bright, massive star near the bubble's center inflates a region within the surrounding molecular cloud. Known as a Wolf-Rayet star, the central star is an extremely hot giant thought to be in a brief, pre-supernova stage of evolution. NGC 2359 is located about 15,000 light-years away in the constellation Canis Major". Source: NASA (science.nasa.gov/ngc-2359-thors-helmet)

Located approximately 6,000 light-years from Earth, the Soul Nebula is an emission nebula that forms a vast star-forming complex that forms part of the Perseus spiral arm of our Milky Way galaxy. The Soul Nebula is also known as the Embryo Nebula, IC 1848, or Westerhout 5. The Perseus arm is located farther from the center of the Milky Way than the arm containing our sun. The Soul Nebula covers an area of sky equivalent to four full moons.

La galaxie du moulinet, ou Messier 101, est une grande galaxie spirale d'un diamètre de 252000 AL (environ 2 fois la voie lactée) et distante de 20 millions d'AL (MAL). Autrement dit, c'est une voisine proche. Quand ses photons partent de ses 100 milliards d'étoiles, des rhinocéros et des éléphants s'ébattent gaiement dans les prairies françaises.
Cette galaxie est très grande dans la voute céleste ; elle fait à peu près la taille de la Lune ... mais elle est très peu lumineuse.

What happens when you do not use the sigma clipping pixel rejection method during stacking but "max" signal? You get to see all the satellite trails and hot pixels (the red, green and blue dots) And passing Asteroid 747 Winchester as a bonus in this case!

The parallel satellite trails to the right are clustered because they belong to a special class of satellites - the geosynchronous satellites.
If you wonder why the satellites leave trails even though they should appear stationary in the sky, the reason is that the telescope is moving (tracking) to compensate for the rotation of the Earth. And because the satellites are at a distance of 35800 km, the position in the sky in this image is also typical for a location at 39 degrees north lattitude (Portugal).

Here is a view of two very dim galaxies hidden to the side of the Heart and Soul Nebula. They are called Maffei I and Maffei II. They were discovered by the Italian Astrophysicist Paolo Maffei in 1967 using infrared emissions. Both are hidden by the dust and gas of our Milky Way galaxy, I was pleasantly surprised to spot these two little blurs using the Williams Optics REDCAT51 scope. The yellow box shows where I zoomed in to show the galaxies on the bottom right view.
If it was not obscured by the Milky Way, Maffei I would be one of the largest and brightest galaxies in our sky, covering an area ¾ the size of the moon! Amazing!

La Galassia del Triangolo, conosciuta anche con il nome di M33 (oggetto numero 33 del catalogo di Charles Messier) e di NGC 598, è una galassia a spirale di tipo SA(s)cd distante circa 3 milioni di anni luce. Si individua nella costellazione del Triangolo. È una galassia piuttosto piccola rispetto alle sue vicine — la Via Lattea e la Galassia di Andromeda — ma in realtà ha dimensioni medie rispetto alle altre galassie spirali presenti nell'Universo. In particolare è il terzo membro del Gruppo Locale per grandezza, dopo la Galassia di Andromeda e la Via Lattea.

IC 63 e IC 59 sono situate nella costellazione di Cassiopea a circa 613 anni luce, le sezioni più brillanti sono costituite dalle due nebulose catalogate nell'Index Catalogue. IC 63 in alto , mostra un'evidente struttura a filamenti di gas, con delle emissioni ottiche dominate dal colore rosso, mentre IC 59 in basso appare come una nube dal colore in parte tendente al blu e priva di una struttura organizzata. In particolare, IC 63 consiste in una regione di idrogeno ionizzato e mostra segni evidenti di fotolisi. Tale fenomeno è molto evidente soprattutto in IC 59, mentre in IC 63 la presenza della forte radiazione ultravioletta suggerisce la formazione di una zona di idrogeno neutro attraverso la dissociazione dell'idrogeno molecolare.

Reprocess of video taken 11/25/2017 using a 3x drizzle process in AutoStakkert!2.
This is an area I have photographed several times over the years. It is a view along the terminator about 8 days after new moon, one day past first quarter. I took the video for this image November 25, 2017.
Many noteworthy craters appear in this image, and they are all familiar friends to those who examine the moon. Two trios of larger craters dominate the image. The upper trio includes the very large Ptolemaeus, Alphonsus, and Arzachel (at center). The lower trio are, from the top, Purbach, Regiomontanus, and Walther (bottom, right of center).
The high ridges where Purbach, LaCaille and Blanchinus craters intersect are responsible for the famous "Lunar X" visual feature. For a few hours, when sunlight first touches these ridges at the First Quarter Moon phase, they shine brightly against the dark, shadowy terminator in the shape of a distinctive "X".
Best 80% of 650 video frames. Preprocessing with PIPP to stretch whites to 90%, and crop to the area shown. Stacking with AutoStakkert!2 (3x drizzle), post-processing in Photoshop CC 2018.

My first record of the Eagle Nebula (the Pillars of Creation are located in its central region). The stacked frames, captured on two consecutive nights, totaled 8 hours of exposure. Gradually, I'm looking to catch up on processing that was delayed due to lack of time.
"The Eagle Nebula (Messier 16, NGC 6611) is a young open star cluster located in the Serpent constellation. It is located approximately 7000 light years from Earth and its apparent magnitude is equal to 6.4. It is a system relatively young, in astronomical terms, only 5.5 million years old ".

"The pillars of creation are clusters of dust and gas of interstellar size in the Eagle nebula. In the name,"pillars" is suggestive of the shape of the place, and the "Creation" part originated due to the location being a huge birthplace of stars ". Source: Wikipedia

The California Nebula is an emission nebula located in the constellation Perseus. Its name comes from its resemblance to the outline of the US State of California. It is approximately 1 thousand light years away from Earth.
I imaged this target over several nights with a total integration time of 11 hours. I used the following equipment:
William Optics FLT132 with Flat8 0.72x reducer/flattener
ZWO ASI2600MC Pro with Optolong L-Ultimate 3nm Ha & Oiii narrowband filter.
ZWO AM5 mount with ASIAir Plus.
I used PixInsight and Affinity Photo 2 for pre and post processing respectively.

The Whirlpool Galaxy, with it's companion galaxy NGC 5195, is an interacting grand-design spiral galaxy with an active galactic nucleus. It is located in the constellation Canes Venatici. It was the first galaxy to be classified as a spiral galaxy. The gravitational interactions between the two galaxies have distorted the spiral arms of Messier 51 and triggered bursts of star formation. Faint clouds and streamers of stars that have been disturbed from their orbits can be seen in the space surrounding the two galaxies.
