It took me 15 years to get a decent image of Andromeda. 15 years of astrophotography...
This particular celestial object is the reason I got into astronomy back in the 70s when I was a wee little boy :D
And the Samyang 135 lens is still surprising me more and more.
ASI1600MM-C, Samyang 135 f/2.0 @ f/2.0, Star Adventurer.
120 x 30 sec Lum, 60 x 30 sec for the R, G and B channels.
Maybe I should try a Drizzle integration.... Hmm...
Only managed to collect 60 minutes in both the oxygen & sulphur channels and 120 mins in hydrogen so far, still needs a good amount more exposure time. Watch this space for further updates!

I was impressed how this came out with so little data. GHS script in PixInsight works wonders pulling the data from only 1.5 hours of exposure. Mind you from a Bortle 2 sky. Enjoy 🌌 ✨ 🔭

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.

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

The Crescent Nebula (also known as NGC 6888, Caldwell 27, Sharpless 105) is an emission nebula in the constellation Cygnus, about 5000 light-years away from Earth. It was discovered by William Herschel in 1792.[2] It is formed by the fast stellar wind from the Wolf-Rayet star WR 136 (HD 192163) colliding with and energizing the slower moving wind ejected by the star when it became a red giant around 250,000[3] to 400,000 years ago. The result of the collision is a shell and two shock waves, one moving outward and one moving inward. The inward moving shock wave heats the stellar wind to X-ray-emitting temperatures.
The red in this photo is Hydrogen alpha (Ha) gas and the blue/teal is O111 (oxygen 3) ozone.

From Wikipedia :
The Bubble nebula is a H II region emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star, SAO 20575. The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow. The radius of the bubble is estimated between 3 and 5 lightyears.

The Orion Nebula is one of the largest and brightest deep-sky objects that exists in our quadrant of the Milky Way galaxy. It is a star forming region that consists of gas and dust that is being excited and illuminated by hot, young stars near to the center of the nebula. Given any clear and relatively dark night during the winter (in the northern hemisphere) it can been seen with the naked eye as a fuzzy "star" in the constellation Orion (look for it as the middle "star" in the sword that hangs below the belt of Orion the Hunter).
Photographed on the morning of October 1, 2013 from a moderately dark-sky location using a 5 inch aperture, f/4.2 telescope and a Sony NEX-5N digital camera (ISO1600, a stack of one hundred and seventy-nine images each exposed for 30 seconds with an additional one hundred and forty-one images exposed for 8 seconds each, producing a total exposure integration time of approximately one hour and 48 minutes). Tracking for each of the exposures was performed by a Celestron CGEM mount (no manual or auto guiding, standard sidereal rate after All-Star polar alignment).
This is a straight RGB image with no narrow-band enhancements that was taken with an unmodified, APS-C format, consumer-grade digital camera (i.e. Sony NEX-5N).
To see a closeup of the central core of the nebula and the famous Trapezium star cluster you can view my post entitled "The Trapezium and the Core of the Great Orion Nebula (M42)" (LINK).

Yesterday I've tried autoguiding for first time and I was very lucky, I was able to get exposure times up to 10 minutes which is a big improvement for me. I did this shot with my non-modified Canon 550D, and I was completely surprised to get Halpha structure (the brown/red in the backround) taking into account that an non-modified Canon 550D has a infrared filter and the sensor isn't sensitive at all in the red range.

Compare to earlier version taken in 2015: www.flickr.com/photos/79387036@N07/22705914083/in/album-7....
The bubble nebula in Halpha taken near end of night's session - had to get some Halpha in
Halpha: 12x5min, binned 2x2
Took me several attempts to get this 3-tile mosaic working, and here is the result. Because of Christchurch's light halo close to Orion at the shooting location, I had a significant gradient across all 3 tiles which caused me troubles. Then tiny black bands screwed up with registration, and finally the usual mix of high noise floor, lack of images due to short summer nights, etc ...
But anyway it was a good exercise to prepare for a mosaic, preprocess it for RGB and Ha images, and I guess it could look worse. I can always tidy up little things here and there, but doubt I would get too much more out of the shots with my current knowledge of PixInsight. ;-)
3-tile mosaic at 120mm focal length, each is a combination of 5 x 120s @ 1600ISO in RGB and 5 x 240s @ 4000ISO through IR645 filter, all at F6.3.
