Az Orion-köd (más néven Messier 42) a Tejútrendszerben elhelyezkedő fényes diffúz köd, amely az Orion övétől délre található. Ez a Földhöz legközelebb lévő masszív csillagkeletkezési régió. A Messier 42 az egyik legjobban ismert ilyen típusú mélyég-objektum. Sokat elárult a csillagászoknak arról, hogyan képződnek a csillagok és a bolygók az itt látható csodálatos por- és gázfelhőkből. Az Orion-ködtől északra található úgynevezett "Futó ember-köd" egy futásban lévő ember alakjára emlékeztet. Az objektum a csillagok fényét kékes színben veri vissza.

I decided to re-image NGC7380, this time with the FLT132 and FLAT8 reducer. I had imaged this one before with the FLT91 (see flic.kr/p/2oWf1hi) and I wanted to see the difference in detail with the larger aperture. As nights are short and only darkish where I live, I imaged this target over three separate nights, getting around 3.5 hours each night.
NGC 7380 is located in the constellation Cepheus about 7,000 light-years from Earth within the Milky Way Galaxy. The star cluster is embedded in a nebula, which spans some 110 light-years. The stars of NGC 7380 have emerged from this star-forming region in the last 5 million years or so, making it a relatively young cluster.

This is the California Nebula (aka NGC 1499) in Perseus, a classic red emission nebula emitting mostly at the red wavelength of hydrogen-alpha light but also with a strong hydrogen-beta emission line in the blue-green part of the spectrum.
By contrast, below is the small blue reflection nebula known only as IC 348, a cloud of dust surrounding hot blue stars and reflecting their light. But the region also contains some dim red emission nebulosity.
Also throughout the field are patches of yellow-brown dust that form obscuring dark nebulas. The main dark nebulas are Barnard 5 (above IC 348) and Barnard 4 below.
This is a stack of 8 x 8 minute unfiltered exposures at ISO 800 blended with a stack of 9 x 15-minute exposures through an Optolong L-Enhance narrowband filter, to bring out the emission nebulas. All were with the Canon EOS Ra camera through the William Optics RedCat 51mm astrograph at f/4.9, equipped with the Starizona filter drawer. Autoguiding was with the Lacerta MGEN3 stand-alone autoguider on the Astro-Physics Mach 1 mount. All stacking, alignment and blending was with Photoshop. Luminosity masks applied with Lumenzia to do selective curves adjustments to various tonal ranges.

Before the clouds came in last night with the snow, I got another few hours of clear, crisp skies and a chance to image another deep sky object. This is the Christmas Tree Cluster and the Cone Nebula (NGC2264) located in the constellation of Monocerous. The red Christmas tree shape is clear, adorned with its blue tinged open star cluster masquerading as the baubles. The Cone Nebula sits at the top of the 'tree' but is inverted in this shot. Deep within the clouds of gas and dust are the ingredients for producing new stars, which burn a fiercely hot bright blue. The red hue in the image is a result of gas clouds glowing as they are hit by ultra-violet light emanating from the newborn stars. The region is about 30 lightyears across and sits 2600 lightyears from Earth, not far in the sky from the Orion constellation.

Referred to as Bode's Nebula, it is however, a spiral galaxy located close to the Big Dipper or Plough asterism in Ursa Major. It has a close companion galaxy M82 the Cigar galaxy, so close together, they are often imaged as a pair.
Lying about 12 million light years from Earth and about 90,000 light years across. Binoculars will pick up M81 as a faint fuzzy patch of light under reasonable sky conditions.
First discovered by a German astronomer by the name of Johann Elert Bode in 1774, hence Bode's Nebula. At the time no one had any clue it was a whole other galaxy.

These filaments are remnants of a supernova that include SH2-96, SH2-94 and SH2-91. The field of view of the FLT132 (even with the 0.72x FLAT8 reducer) doesn't cover the full region, but it offers a closer look at SH2-96, which is rich in Ha (red) and Oiii (blue).
I used my William Optics FLT132, ASI2600MC Pro camera, Optolong L-Ultimate 3nm narrowband filter, on a ZWO AM5 mount. In these short summer nights, I needed two nights and up to 10 minute subs to get some decent signal for a total of just over 7 hours integration time.

The Heart Nebula
The Heart Nebula (IC 1805), lies some 7500 light years away from Earth and is located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. It was discovered by William Herschel on 3 November 1787. It is an emission nebula showing glowing ionized hydrogen gas and darker dust lanes.
The brightest part of the nebula (a knot at its western edge) is separately classified as NGC 896, because it was the first part of the nebula to be discovered. The nebula's intense red output and its morphology are driven by the radiation emanating from a small group of stars near the nebula's center. This open cluster of stars, known as Collinder 26 or Melotte 15, contains a few bright stars nearly 50 times the mass of our Sun, and many more dim stars that are only a fraction of our Sun's mass.

This is a complex of faint nebulas and star clusters in Cepheus:
While this exposure shows the field as one large nebula, the arc-shaped region at top is catalogued as NGC 7822. The region below with dark lanes through it is Cederblad 214. The loose open cluster at right is NGC 7762, with the small yellowish cluster (dimmed by interstellar dust) is King 11. A small, sparse cluster at the centre of Ced214 is Berkeley 59.
The field of view is about 8° by 5.5° with the 250mm focal length RedCat astrograph.
This is a stack of 8 x 8-minute exposures through the William Optics RedCat 51mm f/4.9 astrographic refractor with the red-sensitive Canon EOS Ra camera at ISO 800, and blended with a stack of 8 x 15-minute exposures through the Optolong L-Enhance narrowband filter, with the EOS Ra at ISO 3200, to make up for the nearly 3 stops loss of light from the filter. But it really pops out all the faint nebulosity.
All images stacked, aligned and blended with Photoshop.
Guiding was with the Lacerta MGEN 3 stand-alone autoguider, which also controlled the camera shutter and applied dithering of 10 pixels between each frame to reduce thermal noise without having to apply LENR in camera or dark frames. This was on the Astro-Physics Mach1 mount.

Elaborazione difficile!
Non immaginavo che con oltre 13h di integrazione elaborare il complesso della nebulosa Velo (trattasi del resto di una supernova esplosa alcuni millenni fa) nella costellazione del Cigno fosse cosi ostico e complicato.
Forse alcuni fattori hanno complicato le cose: acquisizione con la presenza della luna quasi piena, trasparenza del cielo spesso non buona, inquinamento Bortle 6-7.
Probabilmente anche la debole luminosità della nebulosa insieme all'uso di un filtro a Banda-Stretta e ai fattori anzidetti hanno reso insufficienti i 300s di posa.
Ad ogni modo ho cercato di fare del mio meglio, anche se sono ancora principiante con i recenti programmi di elaborazione estetica GraXpert e SIRIL. Molto difficile è stato riuscire ad evidenziare le tenui nebulosità Halfa esterne alle nebulose NGC6960 e NGC6992.
Questa elaborazione ha evedenziato 2-3 criticità ottiche del teleobiettivo Zenit Giove 11-A soprattutto quando si utilizzano più filtri ottici contemporaneamente. Spero di trovare un buon compromesso quando utilizzerò questo obiettivo in futuro.

Difficult processing!
I didn't think that with over 13 hours of integration, processing the complex of the Veil nebula (the remnant of a supernova that exploded a few millennia ago) in the constellation of Cygnus would be so difficult and complicated.
Perhaps some factors complicated things: acquisition with the presence of an almost full moon, often poor transparency of the sky, Bortle 6-7 pollution.
Probably also the weak brightness of the nebula together with the use of a narrow-band filter and the aforementioned factors made the 300s exposure insufficient.
However, I tried to do my best, even though I am still a beginner with the recent aesthetic processing programs GraXpert and SIRIL. It was very difficult to highlight the faint Halfa nebulosities outside the NGC6960 and NGC6992 nebulae.
This processing also highlighted 2-3 optical critical issues of the Zenit Giove 11-A telephoto lens, especially when using multiple optical filters at the same time. I hope to find a good compromise when I use this lens in the future.

The North America & the Pelican Nebulaes.
The North America Nebula (NGC 7000) is an emission nebula found in the Cygnus constellation, glowing due to the ionisation of interstellar gas caused by radiation being emitted by hot, young stars.
To the right of the North America Nebula, is a less luminous nebula nicknamed the Pelican Nebula (IC 5070). The two emission nebulaes measure about 50 light-years across, are located about 1500 light-years away from us.
The North America Nebula was discovered by William Herschel in October 1786. It was first photographed by Max Wolf in December 1890.
At first I was supposed to shoot only the North America Nebula. On the second day, the sky was clear, so I decided to shoot the Pelican too with the goal to make a mosaic.
As the nights are short, I just have +/- 3 hours of total exposure for each panel.
Now, the only thing to do is waiting for clear skies !
This picture was shoot during a waxing gibbous moon.

The Carina Nebula (catalogued as NGC 3372) is a large, complex area of bright and dark nebulosity in the constellation Carina, located in the Carina–Sagittarius Arm of the Milky Way galaxy. The nebula is approximately 8,500 light-years from Earth. The nebula has within its boundaries the large Carina OB1 association and several related open clusters. The nebula is one of the largest diffuse nebulae in our skies. Although it is four times as large as and even brighter than the famous Orion Nebula, the Carina Nebula is much less well known due to its location in the southern sky. It was discovered by Nicolas-Louis de Lacaille in 1752 from the Cape of Good Hope.
