Had a go last night 4-1-2022 at the Spaghetti Nebula, hard target to get detail, this was only 10x600sec L-Exstreme - Z61ii - Asi294MCPro - NEQ6-R-Pro - Nina - Stellarium - PH2 - Pixinsight - Lightroom - Bortle 4.
The Spaghetti Nebula (designated Simeis 147 and Sh2-240) is an extremely faint, fairly large supernova remnant of about of 150 light-years across, located some 3,000 light-years away in the constellation of Taurus.
The violent stellar explosion that created the Spaghetti Nebula left behind all that remains of the original star’s core: a spinning neutron star known as pulsar PSR J0538+2817, surrounded by intricate filaments of material.
This expanding remnant has an expansion rate of about 950 kilometers (nearly 600 miles) per second, and is approximately 40,000 years old.

RCW 42- Gum 26, 7 hours of HSO integration with Planewave CDK24 610/3962 f 6/5 telescope, QHY 600M Pro camera, are 42 shots, 14x600 seconds for each filter, processing with Pixinsight and Photoshop. All data and shots were captured with Telescope Live. Gum 26, also known as RCW 42, is a small emission nebula visible in the constellation of Vela.
It is observed in the central-southern part of the constellation, about 2° north of the star κ Velorum, which is part of the asterism of the False Cross; it can be photographed without excessive difficulty with the help of filters through a medium-power telescope. Its strongly southern declination means that from the boreal regions its observation is particularly difficult already north of the tropical belt (north of 38°N it is always invisible). From the southern hemisphere, on the other hand, it can be observed on average for almost all nights of the year. The best time for its observation in the evening sky is from December to May. The nebula lies beyond the Perseus Arm or perhaps on the extreme edge of the Sagittarius-Carina Arm, in an outermost region of the Milky Way; it is a large H II region, one of the most massive known, whose distance is estimated at 6400 parsecs. The cloud hosts a cluster of infrared sources deeply immersed in gases, indicated by number 38 of a catalog of infrared clusters compiled in 2003; however, this study indicates a greater distance for the nebula, up to 7100 parsecs.
According to some studies, this nebula is associated with a giant galactic chimney, indicated by the abbreviation GSH 277+00+36; This superbubble, with a diameter of about 600 parsecs, crosses the entire galactic plane, having a length of 1000 parsecs. The structure appears extremely massive, with a mass of no less than 870,000 M⊙, while its expansion rate would be about 45 km s−1. Through these estimates, an age of the superbubble of about 20-25 million years has been indicated, which for a structure of this size is still very low. A large amount of neutral hydrogen is associated with it, while the column structure that makes up the body of the chimney appears hollow inside. Its origin is not well understood, since at the distance at which it lies it has not been possible to detect stellar objects or galaxy clusters in dissipation; Among the various possibilities was included that of a possible impact of a high-speed cloud with the galactic plane.

With an apparent size and brightness that makes it by far the "biggest" extragalactic object in the night sky, the Great Andromeda Nebula/Galaxy is easily visible to the naked eye (even under relatively poor sky conditions). This image also shows Andromeda's two companion galaxies, M32 (to the left) and M110 (below and to the right). If you look closely, M110 even shows some faint dust lanes/clouds which is a little unusual for a dwarf elliptical galaxy and a feature that is often lost in many photographs.
Photographed on the morning of July 17, 2012 from a moderately dark-sky location using a 5 inch aperture, f/4.2 telescope and a Sony NEX-5N digital camera (ISO3200, a stack of fifty-six images each exposed for 30 seconds, producing a total exposure integration time of 28 minutes). Tracking for each of the 30 second exposures was performed by a Celestron CGEM mount (no manual or auto guiding, standard sidereal rate after one star polar align).

First time using my ZWO autoguiding mini scope and camera, and decided to test it on an easy bright target near the celestial equator.
It performed okay, the images were half decent and I processed them in PixInsight to an extent which makes no sense in regards to how few shots I got and the kind of object ... but it was good practice. ;-)

I also have 6 shots (300" @ F10 and 3200ISO) taken with a 645nm infrared filter, but the lack of resolution and noise messes up the final image if I add it to the red layer. May be I should re-process these infrared images differently ...

The result of yesterdays clear night. Although cloudless the seeing was poor. I managed to capture 4 hours of luminance on M106 before it was too late (work in the morning you know). Those spiral arms are really dim on this galaxy.

Constelación en que se encuentra: Cassiopeia
Distancia: 11.000 años luz
De SkySafari Plus y hubblesite.org: la nebulosa “burbuja” fue descubierta en 1787 por el astrónomo Británico William Hershell está a unos 11.000 años luz y del sistema solar y fue creada por un fuerte viento estelar de la estrella central masiva y joven (unas 45 masas solares) sobre el material denso en la nube molecular circundante. Tiene unos 7 años luz de diámetro.
Por su parte, la nebulosa Sharpless 2-157 (Sh2-157) es una nebulosa brillante a 43.000 años luz del sistema solar. Quiere decir que es unos 32.000 años luz más distante que la “burbuja”.
En la imagen además se ven también las nebulosas Sh2-158, Sh2-159, Sh2-161 y el cúmulo de estrellas NGC7510 que tiene unos 20 años luz de diámetro.

A look at the new Ektachrome 100 on an astronomy target.
Tracking has some issues. This indicates problems that will need to be resolved before trying a deeper exposure.
The good news is that this film shows strong sensitivity to Ha. The reflection nebula of the Trifid shows that the blue sensitivity is lacking. This could also be from the use of the light pollution filter.
Surprising amount of stars recorded with a 20 minute exposure.

These two objects are part of the same emission nebula that is bisected by dust into a fanciful representation of the North American continent and a pelican (right center).
During the late summer and early fall of the northern hemisphere these objects appear almost directly overhead in the night sky near to the bright star Deneb in the constellation Cygnus the Swan. Some claim that under very dark skies the North America nebula can be seen with the unaided eye (i.e. using no telescope or binoculars), but I've always believed that what people are actually seeing is the background starlight of the Milky Way that is outlined by the intervening dust.
Photographed in hydrogen alpha light using a Nikkor 105mm Ai-S lens at f/2.8 and a ZWO ASI174MM camera (just under four hours of exposure, 116 x 2m). Tracked with a Celestron AVX mount (unguided).

i think this is kind of weak sauce here. i've seen many other people with (Ha:OIII:OIII) combos for this object, so i thought i'd try it. however, i found that i got reasonable Ha subs with relatively short exposures (420s) but the OIII subs here are 4x1100s and still there's pretty much nothing there. as a result a lot of the stars are red since there's no data in the G,B channels for them.
i probably should have just done Ha(Ha+R:G:B)... but at this point i've spent a lot of $$ and maybe it's good money after bad? or maybe i should just start over. or do more research before i schedule time :)

I had a very productive 2 weeks at our property at GSV. This is a reprocess of my favorite out of the 4 images I completed during my stay. This is the Dark Shark Nebula (LDN1235) and surrounding dark nebulae. Hope you all enjoy and thanks for any constructive comments.

WR 134, 60 minutes of exposure in SHO with Officina Stellare 700 RC telescope, 700/5600 f 8/0, QHY 600M Pro CCD camera, are 6 shots of which in Ha 2x600 seconds, in OIII 2x600 seconds and in SII 2x600 seconds, processing with Pixinsight and Photoshop. All data and shots were captured with Telescope Live. WR 134 is a variable Wolf-Rayet star in the constellation Cygnus, about 5700 meters from the Sun. Being of magnitude 8.08, it is not visible to the naked eye, but binoculars are sufficient for its observation. The star is surrounded by a faint nebula produced by the intense stellar wind emitted by the star.
It is an inherently very bright star (400,000 times brighter than the Sun). This brightness is not so much due to its radiant surface, as the star has a radius of 5.29 R☉, but to its very high surface temperature of 63,100 K, typical of Wolf-Rayet stars. Like the stars of its class, WR 134 loses mass at very high rates (4 ×10−5 M☉ every year) through very fast stellar winds (1820 Km/s). Born as a star of spectral class O, the star has lost a substantial fraction of its initial mass, which is now reduced to 19 M☉.
The cause of the variability of this star has not yet been precisely established. It has been classified as an Algol-type eclipsing variable and has received the designation V1769 Cygni; however, the variations are irregular and the period varies from hours to days. Morel et al. (1999) identify a period of 2.25 ± 0.05 days in the variations of spectral lines, although it does not have a clear counterpart in photometric measurements. Scholars argue that, rather than the presence of a compact companion (a neutron star or a black hole), the variations must be attributed to an inhomogeneous emission of stellar wind by the star and, therefore, to the rotation of the star on itself.
Rustamov & Cherepashchuk (2012) suggest a period of 1,887 days in spectroscopic variations and irregular variations of 0.1 magnitude with periods of minutes or days in the brightness of the star. They put forward the hypothesis that the spectroscopic variations are due to the presence of a low-mass companion, of spectral class M or K.
WR 134 emits both soft and hard X-rays, but their origin has not yet found a plausible explanation. The X-ray radiation appears to be too massive to derive from a single star. In particular, the shocks that occur in the intense and fast stellar wind should not be sufficient to produce the observed radiation. On the other hand, if a massive companion such as a black hole or neutron star were present, the acceleration it would cause in the stellar wind should produce greater amounts of X-rays than observed.
