Just faffing about using my new found "skills" whilst waiting for the sky to clear (and the moon to reappear!) :) An improvement on the last iteration I think, and much easier to process, although of course still sadly lacking in detail - I can't pull signal out of the hat ;)

Do you know, I sometimes wish my camera was alive, so that I could kill it, or at the very least cause it some severe pain. But it's not, so I have to make do with kicking the cat, who now runs to the end of the garden every time I set up my kit. ;)
This is a vast improvement on this, but is still lacking in detail because of the conditions at the time (and the kit) (and my processing skills). The eastern veil (northern in this) shows much more detail, being the brighter, and even has some elements that could be loosely described as filamentary. :). Enough of the veil already!

I probably should have taken more light frames to try to bring out some of the fainter parts.
Not entirely sure this was worth posting, but gives me something to do whilst I wait patiently for the sky to clear.
I took this on 2 September, having waited since 5 August for a clear sky. Transparency was opaque ( had to concentrate really hard to pick out Cygnus!), but I thought what the hell. So I suppose under those conditions, this could be considered a fair result :) (processing aside!)
I'll give this another go when the visibility is better, and the moon and cloud have gone away.

Because of its immense size, it contains several individually named objects, including NGC 6992 and IC 1340 on the left side as well as NGC 6960 and Pickering's Triangle on the right. Separate, high-quality images of these four objects can also be found in this gallery. To create this image, nine separate images were taken and stitched together. The full-resolution image is over 600 megapixels in size.

NGC 6979 in Cygnus, also referred to as Pickering's Triangle. This is part of the much larger Veil Nebula complex, a supernova remnant.
This is a bi-color image with the Hydrogen-alpha emission as red, and the [OIII] emissions as green-blue.
In this rendition, the H-a color ended up looking like dried blood to me, and the apparent shape of the nebulosity seems to resemble a femur, specifically the pateller region (where it joins the knee).
This is a "draft" image as clouds rolled in and killed my evening about half-way into the planned set. The acquisition data is:
H-alpha 6 X 600s unbinned
[OIII] 4 X 600s unbinned

A quick test of MaximDL mosaic capabilities, 3x2 frames in bicolor Ha/OIII, a varying number of frames per region under partly cloudy skies resulted in ugly, hard-to-remove background flux. But at least I know that the mosaic feature works and it has serious limitations for my intended purposes. Time to roll my own mosaic imaging code.
5 minute sub-frames at 4x4 binning, 2-4 frames per filter per region.
The last time I captured a DSO was at the end of May. Two months felt like a long time not to use my telescope as I enjoy getting out to shoot as often as possible, whether it is landscape, seascape, flowers, nightscape, or DSO.
Clouds would move in and out with small patches of clear sky before being covered in clouds again, which was no surprise as multiple forecasts showed cloudy through the night until at least midnight. I was only able to capture 5 subframes in between all the clouds before we left after 1:30 AM when more clouds prevented me from imaging. I will be revisiting the Veil Nebula in the future.

Once upon a time there were one or two massive stars in the direction of constellation Cygnus. They exploded badly and shined extremely strongly for a short while 10 or 20 thousand years ago. The stars left this gas and dust behind. The irregular and random distribution of gas and dust are expanding at more than 100km/second at 2,400 light-years away from us. The high velocity makes the faint reddish arch surrounding the area like bow shock at the apex of ship. All in all, this is a supernova remnant. Thus they say.
Here is another sample of infrared bow shock in Camelopardalis:

There encroached clouds, and exposure session got short. This is a version made only with shorter exposure frames. Total exposure length was as short as half an hour. I felt this rather natural, clearer, and beautiful.

Ambient temperature was around 13 degrees Celsius or 55 degrees Fahrenheit. Wind was mild.
Finally a clear night - I went back and added more data to my Pickering's Triangle set I started the beginning of the month. I added another 1:40 of exposure time to the H-alpha and [OIII] channels and have done about as much with this as I think I can. I'd love to do more, including mosaic'ing this in with the rest of the veil complex but in the mid-Atlantic where I can expect 3-4 clear nights a month, max, that's a tall order...
I toned down the color balance adjustments, which I could do as the data was better - I could stretch the [OIII] data a bit more. Actually I don't think I did any color adjustment...I might play with it a little but I think a "less is more" is probably best.
I think this is better because in the original the H-a data (mapped to red) looked a little too much like dried blood, which made the the nebulosity look to me like the pateller surface of a human femur - the dried blood color didn't help that imagery...

Veil Nebula in Cygnus. The remnant of a supernova that occurred about 5000-8000 years ago. Just one half of the whole supernova remnant, it stretches nearly 60 ly across. The structure near the bright star to the right is known as the 'Witch's Broom' and the triangular region toward the upper right left is 'Pickering's Triangle'; near the left are the 'fangs' or 'alien face'.

The filaments pictured here are identified as NGC6979 also called the Pickering's Triangle and are part of the Veil Nebula located in the constellation Cygnus. This is glowing gas resulted from the explosion of a massive star approximately 7000 years ago. The shock wave of this explosion sweeps through the interstellar matter and excites the ionized hydrogen atoms to glow in red and the oxygen ones to glow in green-blueish hues.

The Veil Nebula Complex - (NGC 6960, NGC 6992, NGC 6974), 09/25/2021
I went to Ahsahka Idaho again last weekend but this time I just brought my small “travel” setup. This is just an astro-modified Canon DSLR, a 200mm lens and a star tracking mount. This system is definitely smaller, lighter and easier to travel with, but it is a bit more difficult to use and does not give the same results. But I enjoyed the challenge and had fun playing with it. I was able to spend one night capturing this region of the sky.
This is the Veil Nebula Complex. It is the remains of a Supernova that exploded between 10,000 and 20,000 years ago in the Cygnus Loop. This Complex covers an area of sky 36 times the area of the full moon.

The #VeilNebula is a supernova remnant about 2400 light years away in the #Cygnus constellation. When the star exploded to create the supernova 10,000 to 20,000 years ago, it would have been brighter than Venus and visible during the day. This image, taken with a 250mm lens, shows the #WesternVeil on the left and #PickeringsTriangle in the upper right. I will revisit this subject again in the future to try to capture the whole Veil in the same frame. #StillLearning
