This is one of my final projects for the 2020-2021 season before I take a break over the summer months where the skies don't go completely dark. I love imaging dark nebulae and this is by far my favourite, a target that I have imaged before, but wanted to see how far I could push the exposures when imaging North

The Lagoon Nebula (catalogued as Messier 8 or M8, NGC 6523, Sharpless 25, RCW 146, and Gum 72) is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and as an H II region. The Lagoon Nebula is estimated to be between 4,000–6,000 light-years away from the Earth. In the sky of Earth, it spans 90' by 40', which translates to an actual dimension of 110 by 50 light years. Like many nebulae, it appears pink in time-exposure color photos but is gray to the eye peering through binoculars or a telescope, human vision having poor color sensitivity at low light levels. The nebula contains a number of Bok globules (dark, collapsing clouds of protostellar material), the most prominent of which have been catalogued by E. E. Barnard as B88, B89 and B296. It also includes a funnel-like or tornado-like structure caused by a hot O-type star that emanates ultraviolet light, heating and ionizing gases on the surface of the nebula. The Lagoon Nebula also contains at its centre a structure known as the Hourglass Nebula (so named by John Herschel), which should not be confused with the better known Engraved Hourglass Nebula in the constellation of Musca. In 2006, four Herbig–Haro objects were detected within the Hourglass, providing direct evidence of active star formation by accretion within it.

The Elephant's Trunk Nebula or IC 1396 as it is otherwise known, but never with such a wide field of view, at a distance of around 2400 light years from earth and is mainly illuminated by a single bright star. It is thought that this region of space is home to a pretty young star forming region.

The Coma Cluster of Galaxies is one of the densest clusters known - it contains thousands of galaxies. It lies about 330 million light-years away, about seven times farther than the Virgo cluster, in the direction of the constellation Coma Berenices. The main body of the Coma cluster has a diameter of about 25 million light-years, but enhancements above the background can be traced out to a supercluster of a diameter of about 200 million light-years.
Almost every object in photographs of this cluster is a galaxy. Each of these galaxies houses billions of stars - just as our own Milky Way Galaxy does. The Coma Cluster is one of the first places where observed gravitational anomalies were considered to be indicative of unobserved mass.

SH2-112, also known as LBN 337, is a diffuse emission nebula located about 5,600 light-years away in the constellation of Cygnus. This is a circular region of HII with dark dust rifts that can be seen on the western side. The star responsible for its excitation is believed to be BD+45 3216, a double blue star of spectral class O8V with an apparent magnitude of 9.18. It is located in a portion of the Orion Spiral Arm that is noted for areas of rich star formation.

Camera was ZWO ASI120MC-S on my TS 65QAPO telescope. Avi video processed in PIPP Registax. ISS and starfield processed seperatly as different exposure. Pixinsight and PS used.
I have attempted this type of shot a few times now but always failed. There are so many things to get right and little margin for error. Most times I have ended up chasing the ISS with my eye in the finder. Hard do and doesn't give a stable platform. Add to that my capture software seems a bit hit and miss and keeps locking up I have felt like this target was my Nemisis. I have got a few DSLR long exposure trails but I wanted a single detail frame with some stars around if possible.
So I needed to think up a strategy. I then noticed that tonights pass would go close to M13 which is a very easy target to see. The app skyguide, gave me all the info I needed. I fast forwarded the app to 23:20 and could clearly see the ISS track almost clipped one of the two distinctive stars either side of M13. All I had to do was hide in wait at that location with telescope camera and laptop. Easy!
Well not really still a lot to get right. Based on other attempts I nudged the exposure down. My capture software showed about 45 frames per second (USB 3) so if that maintained it would be good. This was on a setting that gave me 1280 x 750 as I conceded a slower frame rate was better than missing the target with a smaller image but higher frame rate.. As it turned out, I had 16 frames with ISS in and I couldn't really have hoped for more. To focus I wanted the closest thing I could get. Moon wasn't available so my focus was on Jupiter. I set the software up to record x1 60 second clip. I had tried repeat clips previously but software didn't carry that out instead it locked up! All ready to go then. All I need is ISS. Sky was staying clear without a hint of cloud on any horizon.
First sight was just left of Jupiter. Here it comes I better get inside the obsy.
The way the track went I couldn't see the early part until it was clear of Leo. But my observatory slot is quite big and I saw it come into view well before it was close to Hercules where M13 is. Didn't want to click start on software to early as it would run for 1 minute.. I estimated about 30 seconds before it gets in my scope and I clicked start.. Horror! Nothing happend! Shit software let me down. Clicked again and it started. 😳 pheww!,
Nothing else I could do now.. So I picked up my binoculars and found M13 easily. Watched it! And there it was whizzing by. Just as predicted. So bright was the ISS that I momentarily lost sight of M13. Made me wonder if I had overdone the exposure.. After 1 minute the recording stopped. I now turned the exposure right up and did a clip of the star field as I wanted to put that into my picture later.. Here is the result. I hope you like it.
Funny to think that as I photographed this the crew were packing up ready for their departure in a couple of days. "safe trip back guys"
Processed in PIPP, Registax, Pixinsight and PS
If anybody has any tips on how I would achieve a better focus on the ISS itself please let me know. If I could just improve that I think my result would be a whole lot better. I think its trial and error time but happy to hear from you.

NGC 7822 is a young star forming complex in the constellation of Cepheus.
The complex encompasses the emission region designated Sharpless 171, and the young cluster of stars named Berkeley 59.
The complex is believed to be some 800-1000 pc distant (3,000 light years), with the younger components aged no more than a few million years.
The complex also includes one of the hottest stars discovered within 1 kpc of the Sun, namely BD+66 1673, which is an eclipsing binary system consisting of an O5V that exhibits a surface temperature of nearly 45000 K and a luminosity ~100,000 times that of the Sun.
The star is one of the primary sources illuminating the nebula and shaping the complex's famed pillars of creation-type formations, the elephant trunks.

In order to trial the famous Blur/Noise/Star-Xterminator plugins for PixInsight, I decided to look at images I captured in July 2020 while testing my newly-acquired Nikon 600mm F4 lens.
Needless to say that these 3 scripts take your images to the next level especially when this is only 6 subs (3x 3' + 3x 2') at 1020mm F6.7 and autoguiding was struggling to control my NEQ6 mount!
Here is the cropped starless version, then tweaked using the usual PixInsight tools + BlurX and NoiseX.
I don't usually like starless images where I find stars do add to the richness of the field of view, but for once I could not resist ... O:)

Had yet another go at processing my ancient data. Slightly less aggressive crop than before and took a bit more time on curves adjustment in Pixinsight. Might have slightly overdone the star reduction as they look a bit sharper/more artificial than the nebula. Anyway I continue to be blown away with what can be dragged out of a mere four hours of integration on a 15 year old camera.

Re-edit of this mosaic using PixInsight 1.8
2-tile mosaic covering the Pipe Nebula and most of "The Kiwi", plus a bit of Sagittarius showing Messier 8 and 20. And as a bonus, Saturn is the bright one bottom centre. :-P
Later in the season I hope to shoot 2 more tiles above, below and to the left of this image, covering a nice big chunk of this amazing region of the sky.
Each tile is a stack of 10 x 180s images shot at 120mm focal length, F4.5 and 640ISO.
Humidity was very high, and for the last few shots I was in thickening fog moving down from the hills ...

Knight Observatory, Tomar.
This is the first time I have ever imaged this object, I will re-visit next year when I will image at F2.8 with a wider field of view using a keller reducer.
Since this object is in the southern area of sky, I am limited by trees and the house on the data I can capture in a single night

*****Linear processing
*** Crop
*** DBE, 1.5 tolerance
*** Star mask creation
* star_mask_large: large scale structure 2, small scale 1, noise threshold 0.1, scale 6, binarize
* star_mask_small: noise 0.15, scale 4, small scale 3 comp 1, smoothness 8, binarize, midtones = 0.02
* star_mask_all - sum of star masks
*** Color calibration
* SNCR 0.5 on green, preserve lightness
* apply a trous wavelet transform to star mask all, keep residual of 4 (blurred_star_mask)
* invert image
* apply SNCR 0.9 on green, preserve lightness
* remove mask
* invert image again
* Background neutralization
* Color calibration w/background and structure detection
*** Deconvolution
* Created range mask - extracted luma, applied standard STF, then histogram shadow = 0.2 mids = 0.25 high = 1 and a trous wavelet transform keeping residual of 4
* Deconvolve with range mask on, 100 interations, luminance, custom PSF, dark 0.025 bright 0.004, local deringing with star_mask_large, wavelet regularization
*** Star reduction
* Apply, erosion operator w/star mask small, 4 iterations 0.15
*** Linear noise reduction
jonrista.com/the-astrophotographers-guide/pixinsights/eff...
*TGV - small noise
Created TGV masks - extracted luminosity, standard stretch (tgv_luma_mask), curved it with black point at ~0.2 and white at ~0.5, moved histogram point to middle (tgv_mask)
apply tgv mask inverted to the image, give luma mask as local support
TGV chroma str 7 edge protection 2E-4 smoothness 2 iterations 500
TGV luma str 5 edge protection 1E-5 smoothness 2 iterations 500
*MMT - larger noise and TGV artifacts

**Initial (fine details)
* created a new multiscale linear transform, kept 4 layers using linear interpolation
* diffed from original image to create a "blurred" version of original image
* extracted luminance from original, used as mask on blurred version
* used curves to create s shape in luminance and pump up saturation a lot
* pixelmath sum the 3, rescaled, back to original image
**Second (galactic colors)
* new multiscale linear transform, keep 5 layers
* diff from original
* extract luminance from blurred image, to use as a mask
* masked blurred image with its own luminance, gave it s-shaped RGB curve, big boost in saturation. Shift pinks to blues with H curve
* pixelmath sum the 3, rescaled, back to original image
**Third (galaxy arms shape)
* new multiscale linear transform, keep layers 6, 7, 8
* diff from original
** extract M31 structure only
* extract luminance from blurred image
* iif(inellipse(2400, 2200, 1250, 400), multi678_L, 0)
* clone out stars and M110
* histogram midtones to 0.2 - m31_mask
*masked blurred image with own luminance, gave big boost in RGB/K, some boost in saturation
* pixelmath sum the 3, rescaled, back to original image
***Local histogram equalization - kernel 192, contrast 1.5, blend 0.5
***Further galaxy adjustments (from www.lightvortexastronomy.com/tutorial-example-m31-androme...)
* Create galaxy_mask: Range mask 0.35-1, smoothness 2, iif(inellipse(2400, 2200, 1300, 450), galaxy_mask, 0), substract star_mask_all, clean edges with clone tool
* Apply
* MLT 8 layers chrominance, pump up bias on 5-8 0.025 0.025 0.05 0.05
* Color saturation raised blues a bit (widely) and reds quite a bit more (more narrowly)
* Remove mask
*** Darken
* DarkStructureEnhancer, 8 layers, 0.7, 3x3
* DarkStructureEnhancer, 8 layers, 0.7, 5x5
* Very slight s-shape on all image luminance
*** Sharpen
* Sharpen with multiscale linear transform, bias layers 2-6 (0.05, 0.05, 0.025, 0.012, 0.006)
