Monoceros R2 is a molecular cloud in our Milky Way about 2700 light years away. New stars are forming in the dark dust lanes.
This image is an integration of multiple 240 second exposures shot separately with Optolong R, G and B filters. Total integration time for each colour channel was over 10 hours. The camera was a QHY163M and the scope was a William Optics FLT110 with Flat4, mounted on a Skywatcher AZ EQ6 GT. Image sequencing was managed by SGP and PHD2, post-processing was carried out in PixInsight with a final run through Topaz DeNoise AI.
Observed from Prachinburi, Thailand.
Bonjour,
Je vous présente la nébuleuse de la rosette dans la constellation de la Licorne, Elle se situe à environ 5400 années lumières.
La prise de vue a été réalisée sous 3 nuits de Lune quasi pleine, le filtre L-extreme de Optolong est très efficace pour ça. Cette image est donc une composition HOO.

The Pleiades star cluster, also known as the Seven Sisters and Messier 45, is a conspicuous object in the night sky with a prominent place in ancient mythology. The cluster contains hundreds of stars, of which only a handfull are commonly visible to the unaided eye. The stars in the Pleiades are thought to have formed together around 100 million years ago, making them 1/50th the age of our sun, and they lie some 425 light years away in the constellation of Taurus.

Da qualche anno pensavo di cambiare il rifrattore Scopos TL805, compagno di tante avventure sotto cieli stellati; quindi dopo tanti dubbi, rinvii e prediligendo un telescopio con un rapporto focale il più basso possibile, visto che l'Inquinamento luminoso spesso mi costringe ad utilizare filtri a banda stretta, la mia scelta è caduta sul tripletto apocromatico Askar 103APO con il suo riduttore 0.6X.
E la sua prima luce nel mese di dicembre non poteva che essere la "Grande nebulosa di Orione" nota anche come "M42" . Con il rapporto focale f/4 è stato bello riuscire e scorgere anche le nubi interstellari più deboli. Mi ritengo molto soddisfatto di questo primo risultato e mi auguro il primo di una lunga serie.
Buon Natale a tutti.
___________
For some years I had been thinking about changing the Scopos TL805 refractor, companion of many adventures under starry skies; so after many doubts, postponements and preferring a telescope with a focal ratio as low as possible, given that light pollution often forces me to use narrow-band filters, my choice fell on the Askar 103APO apochromatic triplet with its 0.6X reducer.
And its first light in December could only be the "Great Orion Nebula" also known as "M42" . With the focal ratio f/4 it was nice to be able to see even the faintest interstellar clouds. I am very satisfied with this first result and I hope for the first of a long series.
Merry Christmas to everyone.

Gesso Valley, in North West of Italy, is one of my best places, even because I started coming here when I was a child.
Mount Argentera is the simbol of this valley: with a height of 3297m is the higher of Alpi Marittime.
Last year I checked that it was possible to have a good alignement of Milky Way Bow and Mount Argentera from Fremamorta Lakes, at the hight of 2375m, that are just in front. And fortunately there is also a nice bivouac to spend the time before and after shooting.
So at the end of June I went there with my backpack full of stuff and an hike of 2 hours.
For this panoramic picture I did 20 shots for the sky and 20 shots for the frontground.
The red light pin you'll see is from Remondino Refuge, one of the most famous refuges of the area.
It's been a year since I have done astrophotography but the last 2 days of cold and crisp weather has provided a perfect opportunity to get out and image again. This image of the Rosette Nebula (also known as Caldwell 49) was taken from the garden in Aberaeron over two successive nights. The nebula is a H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way galaxy. The open star cluster NGC 2244 (Caldwell 50) at its centre 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 5000 light-years from Earth and measure roughly 130 light years in diameter (to put this in context, light from the sun takes just 0.000015561 light years, or 8 minutes, to reach Earth!) 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 10000 solar masses.
This image comprises 88 x 3 minute images stacked and processed to generate a final image.

LBN 420 è una nebulosa molecolare oscura nella costellazione della Lucertola, vicina alla più conosciuta Nebulosa Gecko.La Nebulosa è scarsamente studiata, tanto da non avere un nome ufficiale e da essere priva di ricerche scientifiche, il che la rende un mistero per gli astronomi. Si stima che sia a circa 1.700 anni luce di distanza, basandosi sulla posizione del vicino complesso Lacerta OB1. In basso si può notare la NGC 7223 una galassia a spirale barrata.

Messier 78 Reflection Nebula in the Constellation Orion
Messier 78 or M 78, also known as NGC 2068, is a reflection nebula in the constellation Orion. It was discovered by Pierre Méchain in 1780 and included by Charles Messier in his catalog of comet-like objects that same year.
M78 is the brightest diffuse reflection nebula of a group of nebulae that includes NGC 2064, NGC 2067 and NGC 2071. This group belongs to the Orion B molecular cloud complex and is about 1,350 light-years distant from Earth. M78 is easily found in small telescopes as a hazy patch and involves two stars of 10th and 11th magnitude. These two B-type stars, HD 38563 A and HD 38563 B, are responsible for making the cloud of dust in M78 visible by reflecting their light.

In this image the major areas of nebulosity of the constellation Sagittarius can be seen, the Lagoon Nebula (M8) the bright reddish one in the center, the Trifid Nebula (M20) the red and blue one towards the upper left, and last but not least NGC 6559 which is the red/blue somewhat dimmer area of nebulosity below the Lagoon Nebula.
Another prominent feature('s) is the dust-lanes and yellow clouds of the central bulge of the Milky Way towards the right. There are also a couple Globular Clusters, NGC 6544 just below and to the right of the Lagoon Nebula, and NGC 6553 which is further to the bottom right appearing in this image as a fuzzy bright spot in the clouds of the Milky Way. Finally there is the open cluster M21 down and a little to the left of the Trifid Nebula.

IC 1805 ,nota anche come Nebulosa Cuore o con la sigla W4, è una nebulosa diffusa in associazione ad un ammasso aperto, visibile nella costellazione di Cassiopea, verso il confine con la Giraffa.
E' visibile circa 6 gradi a sud-est della stella ε Cassiopeiae, ma si può individuare anche partendo dall’Ammasso Doppio di Perseo e spostandosi di circa 4-5 gradi in direzione nord-nord-est; Per poterla individuare occorre un telescopio con un grande diametro, non tanto per le dimensioni, dato che la nebulosa è abbastanza estesa, quanto per la sua debolezza. L’intero complesso di nebulose visibili in quest’area si presenta circumpolare dalla gran parte delle regioni dell’emisfero boreale.
Si tratta di una regione HII molto estesa, la cui distanza è stimata sui 7500 anni luce da noi; la sua caratteristica principale è la presenza di due grosse aree apparentemente vuote, di diverse dimensioni, che rendono la nebulosa simile ad un “cuore”. Al suo interno si trova un sistema di piccoli ammassi aperti poco concentrati, responsabili della ionizzazione della nebulosa. Il più notevole di questi è Melotte 15, che contiene alcune stelle circa 50 volte più massicce del Sole, più altre più piccole ed un microquasar espulso milioni di anni fa.( Melotte 15 visibile al centro della foto).
Questa e la vicina IC 1848 formano un grande complesso nebuloso noto come complesso W3/W4/W5 o “Cuore e Anima”; il “cuore” è IC 1805 in foto , mentre l'”anima” è rappresentata da IC 1848, prossime riprese !!
W4 ha una struttura a guscio ed è la più grande fra le tre nebulose principali del complesso; al suo centro si trova l’ammasso aperto IC 1805, designazione con cui talvolta viene indicata anche l’intera nebulosa ad esso associata. Di fatto IC 1805 costituisce la parte centrale della grande associazione Cassiopeia OB6; le stelle più brillanti dell’ammasso sono delle nane blu, 24 delle quali possiedono una massa superiore a 10 M☉, con un’età compresa fra 1 e 3 milioni di anni. Fra queste stelle blu ve ne sono 9 di classe spettrale O, racchiuse entro un raggio di circa 10 pc, mentre il raggio totale dell’ammasso aperto è di circa 18 pc. Di queste stelle di classe O, si è scoperto tramite studi sulla velocità radiale e della curva di Gauss che 6 sono stelle doppie; fra queste ve n’è una, HD 15558, che pare essere una stella tripla.
Nei pressi della nebulosa sono attivi degli episodi multipli di formazione stellare; tramite le immagini ottenute nell’H-α è stata scoperta una superbolla in espansione formata da idrogeno ionizzato dell’estensione di 1200 pc ed emergente dal piano galattico, la cui età, di circa 10-20 milioni di anni, è un’indicatrice del fatto che si sia originata a seguito dell’azione del vento stellare di una prima generazione di stelle massicce. Da questa regione emergono oltre 30 nubi molecolari e globuli dispersi nello spazio circostante, come visto sopra, la cui presenza suggerisce che una volta nella regione si trovava una nube molecolare gigante in seguito dissoltasi a causa di un primo intenso episodio di formazione stellare.

Seeing varied between 4 and 4.5 out of 5 this night, and transparency was decent. Jupiter was at an altitude of 39° and a distance of 601 million km.
Separate R, G, and B SER files were captured between 0626 and 0647 UTC. Each SER was 30 s in length. This produced 7 usable stacks for R images, 7 for G images, and 6 for B images. Each stack was 175 frames for R, 200 frames for G, and 230 for B. The images for each color band were de-rotated in WinJUPOS, and the resulting single R, G, and B images were compositied and derotated in WinJUPOS.

L'Amas NGC 1502 et l'astérisme de la cascade de Kemble (Kemble 1) sont situés dans la constellation de la Girafe. L'astérisme est formé par l'alignement d'une vingtaine d'étoiles comprises entre la cinquième et la dixième magnitude, et qui s'étale dans le ciel sur un diamètre apparent équivalent à cinq pleines lunes (wikipedia).
Kemble's Cascade is an asterism located in the constellation Camelopardalis, next to the star cluster NGC 1502.

This is a very rarely imaged object. Google finds no images on the internet neither does ChatGPT, (with the exception of a couple of images of NGC 6337 with a smallish portion of RCW 123 in the background found in Astrobin).
Nevertheless it presents very interesting structure even in RGB; a narrow band version may also be a worthwhile exercise.
Delighted to resolve the Cheerio Nebula- NGC 6337 which would a great target for anyone with a long focal length imaging system
7 hours and 10 minutes of integration, spread over two session. Used an Optolong UV/IR filter for session one and an Optolong L Extreme filter for the second session

While I have the equipment disarmed to make some improvements especially on the focuser to avoid tilts on the imaging train and guidescope mount to avoid differential flexing, I set about reprocessing some recent images, trying to apply everything I have learned lately.
I Hope you enjoy it, clear skies!

The Heart and Soul Nebula (IC 1805 and IC 1848) two panel mosaic. This two panel mosaic shows a wide field view of the Heart and Soul Nebula (previously imaged separately). Each panel was a combined 60-minute exposure, the final mosaic stitched together using Microsoft Image Composite Editor (ICE).
The Heart Nebula is masking two deep sky objects that I was surprised to pick up in a wide field view, I'll share these in the next image.

#IC5070, conocida como Nebulosa del Pelícano está ubicada en la constelación Cygnus. Es una región muy activa en formación de estrellas y, además, sus nubes de gas están en evolución, lo que en millones de años hará cambiar su forma . La luz de las estrellas jóvenes ioniza los gases de la nebulosa y aún existen filamentos densos de gas frío.
