East Veil Nebula - 2022-07-19

masterLight frame integrated in PixInsight, Red channel only. with STF stretch applied.

The image looks to be over calibrated by the Flats in that the dark vignetting in the corners of the Light subs now appear bright in the integrated master. Suspected problem is that Darks (45s) and Dark Flats (2s) do not have the same offset.

Both Darks and Dark Flats were captured with ZWO ASI6200MM using the ZWO ASCOM driver, which I believe should have applied Offset of 50 (DN 500) to both sets of subs. Both sets of subs look normal with a boosted STF stretch.

So far I have found that the Median and Min data numbers for the Dark subs are 11.0 and 0.0, respectively. TheMedian and Min data numbers for Dark Flat subs are 501.0 and 324.0, which seems in line with what I expected.

I believe that the Darks are not correct, and will produce another set.

Sharpless 2-112 is a diffuse emission nebula in Cygnus, located on the surface of a huge sphere of cold, molecular hydrogen. The nebula is illuminated by an intensely hot, young star, seen at the center. The star has about 30x the mass of our sun and radiates strongly in ultra-violet.

The Rosette Nebula (also known as Caldwell 49 or Sharpless 275) is a large spherical ionized atomic hydrogen region (H II region) that is circular in appearance and located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter (from Wikipedia). The nebula is about 5,200 light-years away and spans nearly 65 light-years. This version has been processed using the Hubble Palette and the stars have been removed from the image..

Merry Christmas with a beautiful nebula from the "Christmas Tree Cluster", located in the constellation of the Unicorn. Yes, I know. It's too good to make this stuff up!

A HaRGB image of the Fox Fur Nebula, located in Monoceros, and included in the NGC 2264 Region (also know as Sharpless 273).

This enigmatic formation of gas and dust lies in the constellation of Monoceros (the Unicorn) not far off the right arm of Orion. This is a small section of a much larger complex, generally known as the Christmas Tree cluster. The Cone Nebula is also a part of this same cloud.

The red regions of this nebula are caused by Hydrogen gas that is excited by the ultraviolet radiation from the hot, blue stars of the nearby star cluster. The blue areas are mainly dust clouds that reflect the bluish light of the same stars.

About the Star Colors:

You will notice that star colors differ from red, orange and yellow, to blue. This is an indication of the temperature of the star's Nuclear Fusion process. This is determined by the size and mass of the star, and the stage of its life cycle. In short, the blue stars are hotter, and the red ones are cooler.

One of the most interesting active regions in the Large Magellanic Cloud (one of the Milky Way's satellite Galaxies).

The Tarantula Nebula is the most active starburst region known in the Local Group of Galaxies. The Local Group comprises more than 54 Galaxies (mostly dwarf Galaxies). The three largest members of the group (in descending order) are the Andromeda Galaxy, the Milky Way Galaxy and the Triangulum Galaxy.

The Tarantula Nebula (also known as NGC 2070, the Doradus Nebula, or 30 Doradus) is a H II region in the very dense Large Magellanic Cloud (LMC). The LMC is one of the irregular satellite dwarf Galaxies of the Milky Way Galaxy, that is among the closest Galaxies to Earth. There is also a Small Magellanic Cloud (SMC), both discovered by Magellan. The Magellanic Clouds are visible from the Southern Hemisphere with the naked eye.

Note from 2015 (modified for the new processing using Pixinsight)

------------------------------------------------------------------------------

HFG1 (Heckathorn-Fesen-Gullis 1) is a very faint and large (huge), ancient planetary nebula in Cassiopeia, with almost no Sii, small Ha, and a moderate amount of Oiii emissions. The more stereotypical, "bubble"-shaped Abell 6 has both Ha and Oiii. Note a bow shock surrounding HFG1 and a faint Ha tail. As other postings at AB and other sites commented, this has turned out to be one of the most difficult imaging I have done so far with C8 Hyperstar 3 (stopped down to F/3) +Atik460ex+5nm Astrodon filters. Shot over 3 nights in an unusually hazy October sky from Grandview Campground, Inyo, CA. Ha, Oiii, and Sii were used to generate both HST and synthetic natural color palette images, which were blended and used.

M 17 - Omega Nebula with Chile Two telescope of the Slooh network and processing with Pixinsight and Photoshop. The Omega Nebula (also known as the Swan Nebula, Horseshoe Nebula, Lobster Nebula or by the catalog abbreviations M 17 and NGC 6618) is an emission nebula, discovered by de Chéseaux in 1746 and rediscovered by Charles Messier in 1764, located in the constellation Sagittarius. Due to its brightness, The Omega Nebula is rather easy to locate: it is located 2° southeast of the star γ Scuti. it is easily identified even with binoculars 10x50 or even smaller, if the sky is dark and clear: it shows itself in these instruments as an elongated spot; through a 114 mm instrument, equipped with a UHC filter, it reveals most of its nuances and its play of light. From 200 mm the vision is exceptional, and it is better to take a long pose photo to capture the pink color.

The Omega Nebula can be observed with reasonable ease from most of the populated areas of the Earth, thanks to the fact that it is located at a declination not too austral: in some areas of Northern Europe and Canada, near the Arctic Circle, its visibility is however very difficult, while in central Europe it appears relatively low; From the southern hemisphere the nebula is clearly visible high in the nights of the austral winter and in its tropical belt can be seen perfectly at the zenith. The best time for its observation in the evening sky is between June and October.

It took me a long time to calibrate the optics and I think I did a pretty good job. A bit of fiddling with adaptors got the spacing right for backfocus.

But the actual focus on the images is slightly off, not sure if it moved after I set off the imaging run or whether I didn't get it right at the start.

No flat frame calibration carried out.

The Iris Nebula can be a tricky target due to the amount of dust and dark nebulosity around, which can be easily mistaken for noise or light polution, but also equally it is very easy to over expose the core. Whilst I have some sort of reflection in the lower left corner, I am very happy with the way this image turned out, there's a lot of detail around the nebula

The North America Nebula (NGC 7000) is an emission nebula in the constellation Cygnus. The name “North America Nebula” was coined by Dr. Max Wolf (ref: Burnham’s Celestial Handbook, Volume 2, by Robert Burnham Jr.) no doubt from his work with E.E. Barnard on dark nebulae. This image was processed by first removing the stars followed by processing the nebula.

The North America Nebula covers a region more than ten times the area of the full moon, but its surface brightness is low, so normally it cannot be seen with the unaided eye (Wikipedia).

The Andromeda Galaxy M31 is the 2nd furthest object visible to the naked eye. This is my wide field take on the target using an unmodified Nikon D750 full frame camera and my trusty 135mm f2 manual lens. It should be noted that every star you see here is in our own Milky Way Galaxy. Captured back in September while exposing another shot I had plenty of time to pull out my other camera and Skytracker to see what other targets were ripe for the picking. Hoping to capture some more photons in the coming week with my freshly modified D5600a. Stay tuned! 📷🔭🌌

Located 6,500 light years away in the constellation of Taurus. This spectacular planetary nebula is what's left of a star that Chinese astronomers witnessed going supernova in the year 1054, reported to have been visible in the daytime for up to 4 weeks!

First discovered by John Bevis in 1731 and then later by Charles Messier, who mistook it for Halley's comet. Leading him to create a list of objects that weren't comets, so he wouldn't be wasting his time on them. This list is known today as the Messier catalogue.

Data was captured at The Astronomy Centre, Todmorden, UK on 10th of November 2023.

First ever processing with Pixinsight.

It seems that Pixinsight is the way to go for processing astrophotos but it comes with a hefty bill. I acquired the LE version of Pixinsight and started to do some reprocessing. I must say that it is a powerful tool and when used correctly it will make your images look great.

Here is my first ever photo processed with Pixinsight LE and I am happy with the results. I was able to get more of the faint stuff to pop out as well as a nice color balance.

Some day I may fork out the cash for the full version but for now I am content on using this version.

I would love to here some feedback as there is a steep learning curve with this program. Any tips on using this software would be appreciated.

notes: obviously ran out of time on this one - the moon is back and anyway the clouds have returned. the L and B would support a much more aggressive stretch, but the other channels don't permit it.

foolishly did not center the LRG frames on the B acquired last year, so this is a crop. tried 300s lights first at B and found some bad reflections probably from the reducer. dropped to 180s. however, the framing for the LRG images did not show the same reflections, so likely i should re-shoot the blue with that framing. on the other hand this thing is brighter in B so perhaps i'm stuck. there's a blue blotch in this image that does not belong…

will revisit this later; i have some shorter exposures to blend in to recover the star colors and profiles, but only for 2 of the channels...

Messier 92 (also known as M92, M 92, or NGC 6341) is a globular cluster of stars in the northern constellation of Hercules. Located 27,000 light-years from Earth in the constellation Hercules, this globular cluster was first discovered by the German astronomer Johann Elert Bode in 1777. With an apparent magnitude of 6.3, M92 is one of the brightest globular clusters in the Milky Way and is visible to the naked eye under good observing conditions. It can be most easily spotted during the month of July. The cluster is very tightly packed with stars, containing roughly 330,000 stars in total.

I tested out the Starnet++ pixinsight module this weekend on my previously collected data. It is an impressive tool for Pi, although I feel I have more control manually doing this in photoshop, what I did realize is that there are alot of powerful things I can do to the starless data in Pi that I do not know how to do in photoshop. Its a fun tool to use and really lets you dig into faint darksite data.

This is obviously an extremely overstretched example but really shows some otherwise hidden structures.

Omega Centauri with Chile Two telescope of the slooh network, processing with Pixinsight. Omega Centauri (also known as C 80) is commonly classified as a globular cluster, the brightest observable from Earth. It is observed in the constellation Centaurus. It is probably what remains of a dwarf galaxy absorbed by our Milky Way; In fact, a black hole was found inside. Omega Centauri can be observed without difficulty on clear nights even with the naked eye; However, its declination of -47° means that it is observable only from the fortieth parallel north, and that it is visible without difficulty only from the Tropic of Cancer. Some observers have exceptionally seen it through a telescope and photographed it from latitude 42° north.

It looks like a third-magnitude star, apparently a little blurred, to the north-east of the bright constellation of the Southern Cross; With binoculars or an amateur telescope it shows itself instead as a large nebulous spot, extended over half a degree in diameter and brighter in the center. For its complete resolution requires a powerful telescope.

Its declination is strongly austral, therefore this object is not observable from many of the inhabited regions of the northern hemisphere, such as almost all of Europe and much of North America; From some inhabited regions of the southern hemisphere, on the contrary, it is circumpolar. The best time for its observation in the evening sky is between February and August
