Messier 74 (also known as Phantom Galaxy) is a spiral galaxy in the constellation Pisces. It’s at a distance of about 32 million light-years away from Earth. The relatively large angular size and the face-on orientation make M74 an ideal example of a grand design spiral galaxy. The galaxy contains two clearly defined spiral arms but its low surface brightness makes it the most difficult Messier object for amateur astronomers to observe. It’s estimated that M74 is home to about 100 billion stars

Sh2-73 è una nebulosa a riflessione visibile nella costellazione di Ercole. Scambiata in origine per una regione HII, si è poi scoperto che è illuminata dalla nostra galassia nel suo insieme, e fa quindi parte delle cosiddette "IFN" (Integrated Flux Nebulae). Si osserva nella parte sudoccidentale della costellazione, al confine con la Testa del Serpente e la Corona Boreale; si presenta come un debolissimo filamento appena percepibile nelle foto astronomiche sensibili e completamente invisibile alla semplice osservazione amatoriale. Sh2-73 è una delle nubi più vicine al sistema solare, essendone distante appena circa 650 anni luce, si trova ad una latitudine galattica molto elevata e non appare associata ad alcuna stella luminosa, né in essa sono attivi fenomeni di formazione stellare.

This is a portrait of the main glowing nebulas amid star clusters in central Auriga, the Charioteer.

The main nebula at right is the Flaming Star Nebula, aka IC 405. But in this long exposure its mass blends into the central roundish nebula, IC 410. At top left is the pair of Sharpless nebulas, Sh 2-232 and the small Sh 2-235. The fingerlike nebula at top centre is Sh 2-230. The star cluster just to its left is Messier 38, with the small cluster NGC 1907 just below M38. The star cluster at left centre is Messier 36. At centre frame is the nebula IC 417 around the cluster Stock 8. The line of colourful stars at lower right between IC 405 and IC 410 is the Little FIsh or Flying Minnow asterism, aka Mel 11.

This is a stack of 11 x 12-minute exposures at ISO 3200 through an Optolong L-Enhance dual-band nebula filter, blended with a stack of 12 x 8-minute exposures without a filter (for more natural star colors and the blue reflection nebula in IC 405) at ISO 800. All with the Canon EOS Ra camera through the f/5 51mm William Optics RedCat astrograph with a Starizona filter drawer. Autoguiding was with the Lacerta MGEN3 autoguider which applied a dithering shift between each frame to help cancel out thermal noise when stacking. No darks or LENR were used here on this mild winter night at -5° C or so.

All stacking, alignment and blending was in Adobe Photoshop 2021. Luminosity masks (DM2, D and M) applied with Lumenzia helped bring out the faint nebulosity.

Messier 33 (M33), also known as the Triangulum Galaxy, is a famous spiral galaxy located in the small northern constellation Triangulum.

The Triangulum Galaxy is the third largest galaxy in the Local Group, after the Andromeda Galaxy and the Milky Way.

It is also the second nearest spiral galaxy to the Milky Way.

This galaxy lies at a distance between 2.38 and 3.07 million light years from Earth.

Charles Messier found the object and catalogued it on August 25, 1764.

A lot of "First Time" for this pictures. Multiple Nights Stacking, Ha and RGB Combination, First Real Session with the New Refractor, First Time Drizzle.

This pictures was supposed to be about 4 days, but the first was a Full Moon day, so I had to drop all my subs.

After that, I had 3 mostly clear nights to shoot with the LPRO & the L-Extreme. I had to drop a lot of subs because of clouds.

The Post processing took me a lot of times (I "gave up" a bit and switch to the data of the Pacman Nebula :p) as I had a lot of things to learn. But the final result seems me pretty cool as I wanted to keep the color "natural" as much as possible.

Really happy with the result.

Messier 45, The Pleiades or The Seven Sisters, is an open star cluster containing young, hot B-type stars situated in the constellation of Taurus. It lies at a distance of around 444 light-years and is one of the nearest star clusters to us. The cluster is dominated by hot blue luminous stars that have formed within the last 100 million years. Reflection nebulae around the brightest stars were once thought to be leftover material from their formation but are now considered likely to be an unrelated dust cloud in the interstellar medium through which the stars are currently passing.

Imaged over 2 nights, the 2nd and 7th January 2025.

A widefield LRGB and SHO (SII+Ha+OIII) Narrowband image of the Bubble and Lobster Claw Nebula. The Bubble Nebula is also know as NGC 7635, Sharpless 162, or Caldwell 11 (a H II region emission nebula) in the constellation Cassiopeia. It lies close to the open star cluster Messier 52.

Also take a look at a closer view of the Bubble Nebula.

The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star, SAO 20575 (BD+60°2522). The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow.

The Lobster Claw Nebula (Sharpless 157), is a bright emission nebula, and is clearly visible at the bottom right.

Another prominent Galaxy in this image is the Elliptical Galaxy M86 shown lower right in this image, M86 has the distinction of having the highest Blue Shift of any Messier objects and is headed towards our Milky Way Galaxy. Together with NGC4438 & NGC4435 they lie at The Heart of the Virgo Cluster Of Galaxies within the constellation of Virgo at a distance of around 52 Million Light years from Earth

The Rosette Nebula (also referred to as NGC2244 and Caldwell 49) This active star forming nebula lies in the Monoceros Constellation (the Unicorn) only 5,200 light-years distant. The dense cloud of hydrogen has been condensing to form new stars and is thought to be very similar to the environment that gave birth to our own Solar System. As the new stars ignite they blow off their shrouds and irradiate thier surroundings and cause the hydrogen to glow from the ionizing radiation. Like dust being blown by the wind, these newborns push the hydrogen and dust away where it collapses under gravity to accelerate the formation of yet more stars, excavating the inner region of the nebula over time.

A few weeks ago I processed a Hubble Palette version of this same region seen here: www.flickr.com/photos/terryhancock/49058519297/in/datepos... this latest wide field process of the Rosette Nebula otherwise known as Caldwell 49 using data from Grand Mesa Observatory’s system 1a the William Optics Redcat with QHY16200A monochrome CCD was photographed in H-Alpha and LRGB.

Sharpless 101 (Sh2-101) is a H II region emission nebula located in the constellation Cygnus. It is sometimes also called the Tulip Nebula because it appears to resemble the outline of a tulip when imaged photographically. It was cataloged by astronomer Stewart Sharpless in his 1959 catalog of nebulae. It lies at a distance of about 6,000 light-years from Earth. Sh2-101, at least in the field seen from Earth, is in close proximity to microquasar Cygnus X-1, site of one of the first suspected black holes. (Ref: en.wikipedia.org/wiki/Sh2-101)

My processing includes a modified Hubble Palette using PixInsight and added JWST diffraction spikes using Corel PaintShop Pro.

New Process, this area is a very densely packed star region and I felt a lot of data was hidden so carefully I reprocessed it and I was able to reveal much more of the very faint nebulous regions in LBN 487

What's California doing in space? Drifting through the Orion Arm of the spiral Milky Way Galaxy, this cosmic cloud by chance echoes the outline of California on the west coast of the United States. Our own Sun also lies within the Milky Way's Orion Arm, only about 1,500 light-years from the California Nebula. Also known as NGC 1499, the classic emission nebula is around 100 light-years long. On the featured image, the most prominent glow of the California Nebula is the red light characteristic of hydrogen atoms recombining with long lost electrons, stripped away (ionized) by energetic starlight. The star most likely providing the energetic starlight that ionizes much of the nebular gas is the bright, hot, bluish Xi Persei just to the right of the nebula. A regular target for astrophotographers, the California Nebula can be spotted with a wide-field telescope under a dark sky toward the constellation of Perseus, not far from the Pleiades.
