This is the result Of shooting three nights in a Row with out a moon or clouds. In total 68 shots or 11 1/2 hours shot time I had the trees one side and the house the other so limited my number of shot to 30odd a night. The shots guided with PHD2 Dev3 which proved very good at guiding. For the first time editing done in Pix Insight, Photoshop and Finished out in Light room. This is the Skywatcher ED 80 scope at work with the D810 the extra detail that came out with each night photos added made this worth while.
Getting to know Nina better.

The Perseus double cluster complex imaged during a brief period of clear weather on night of 9th October. Consisting of two open star clusters NGC869 (top) and NGC884 (below) the complex lies at a distance of around 7500 lightyears from us.
Both clusters contain hot white and blue-white comparatively young stars as well as some supergiant red ones. These red/orange stars are more numerous within NGC884.
The clusters are physically close in space and are believed to contain at least 300 hot-white and blue-white super massive, super-luminous, giant stars in each cluster.
Conditions were not great with clouds coming and going with variable transparency on Saturday night. Eventually fog and mist moved in calling a halt to my imaging session and I had to trash a number of exposures.
Imaged with my little Skywatcher 72ED refractor with flattener and a ZWO ASI2600MC camera.

Another trip into space, this time to Orion that, at present, rises above the horizon late in the evening and is visible higher up in the sky from midnight onwards. The Horsehead Nebula is an iconic dark nebula in the Orion constellation. Along with the nearby Flame Nebula (to the left in the image) they are part of the much larger Orion Molecular Cloud Complex. Compared to some nebulae, this one is very easy to find - it is located near the most eastern star in Orion's Belt, Alnitak and is 1500 light years from Earth.

After cloud cover all day a brief unexpected clearance last night allowed me to image the waxing moon.
The moon is approx. 85% illuminated and the brightest area of the moon, the crater Aristarchus, is nicely contrasted within the gloom of the lunar terminator. (LHS)
The subtle colour variations within the moon's surface are also nicely revealed.
My small short focal length refractor, a Skywatcher ED72, was already mounted and I attached it to a Nikon D5300 DSLR to capture this image.
Luna 19 May 2013.
I was determined to try my first real session of astrophotography using my new telescope last night, but a failure to correctly polar align, as well as incoming clouds put an end to that idea.
I did however manage to observe saturn which was amazing, and of course Luna.
This was taken prime using a Canon 1000D (baader modified) through my Skywatcher 200P-DS. I need to get a 2" barlow :)
P.S It makes a lovely iPad mini homescreen image :)
Found in the constellation of Orion (near the feet of Gemini!) NGC 2174 is an HII emission rich nebula.
Lying at a distance of 6,400 light years the nebula is a stellar nursery where hot, new stars are being formed.
I was able to gather some OIII data in addition to the Ha data I had acquired on the 23 & 26.02.19.
The Ha data was mapped to the red channel and the OIII data was mapped to the blue channel.
A synthetic green channel was created using a blend of the blue and red data.
A blend of the Ha and OIII data was used as luminance.
Imaged with a focal reduced Skywatcher ED80 refractor and a ZWO 1600MM Pro camera cooled to -15C. I used Baader narrowband filters.

This is 12 shots(6x2) as the milky way rises in our Southern Skies as per the plan by Nina, This Is Not Seen North Of The Equator. This is halfway to where I want to get there is another panorama of 12 shots to go to get to the panorama I took last year. Each Panel is a night worth of shots then added to PtGui to get the panorama. There positively no edits on the stars this is the number that the camera can see.

This image shows the AZ-GTI carrying a heavy load with a William Optics Megrez 88 telescope, a ZWO ASI 1600MM Pro astro camera, a filter wheel and an autoguider.
The images I take with my Skywatcher AZ-GTI mount raise many questions about how I can use this ALT/AZ mount for astrophotography.
I recently wrote an article about the topic that should answer most of these questions. You find it under:

This is an image of the Sunflower Galaxy in Canes Venatici.
Discovered by Pierre Méchain in 1779 it lies at approaching 30 million light-years from earth and is some 100,000 light-years across. It was catalogued by Charles Messier as M63. The galaxy is also catalogued NGC 5055.
The galaxy has been given its moniker because of its resemblance to the dense, seedy head and overlapping petals of a Sunflower!
M63 is what is known as a flocculent spiral galaxy. These galaxies are characterised by their patchy, feathery, flaky or lumpy disjointed arms giving a mottled appearance. The Sunflower has only 2 spiral arms but the flocculate appearance makes it hard to define them.
Surprisingly, flocculate galaxies actually make up 30% of spiral galaxies with only 10% being grand design spirals - the more common perception of what a galaxy should look like!
A prominent dust lane is visible in the galaxy at front left.
Imaged with a Skywatcher Esprit 120ED and a ZWO 2600MC camera.

An image of Friday night's (24th) waxing gibbous moon. The moon was almost 12 days old and almost 92% illuminated.
The full moon on the 27th November is also known as the Beaver Moon in Native North American culture. It is also known as the Freezing or Frost Moon as a nod to the weather conditions which become prevalent at this time of year.
Imaged with a Skywatcher Esprit 120ED and a ZWO 2600MC. Some nice subtle colours evident which are as a result of the lunar geology. Comparatively Titanium rich areas giving a bluish colour, whilst those areas richer in Iron account for the more brown regions. The radiating ray systems of Copernicus and Tycho craters are well seen.

[EDIT : retraitement complet en palette Hubble (RGB + Hubble HOO)]
Sur cette photo, j'ai capturé la grande nébuleuse d'Orion SH 2-281 et une petite partie de la nébuleuse de l'homme qui cours SH 2-279 en dessous sur la photo.
Ces nébuleuses sont distantes de 1350 années lulières et ont un diamètre de 24 années lumières. Ce sont des nébuleuses en émission (les gaz chauffés par les étoiles voisines emettent de la lumière) et en réflexion (les gaz et poussières reflettent la lumière des étoiles).

[EDIT: Complete reprocessing in Hubble palette (RGB + Hubble HOO)]
In this photo, I captured the Great Orion Nebula SH 2-281, along with a small portion of the Running Man Nebula SH 2-279, visible at the bottom of the image.
These nebulae are located about 1,350 light-years from Earth and span approximately 24 light-years in diameter.
They are both emission nebulae (where gas heated by nearby stars emits its own light) and reflection nebulae (where dust and gas reflect the light of surrounding stars).

Wiki: The Dumbbell Nebula (also known as the Apple Core Nebula, Messier 27, and NGC 6853) is a planetary nebula (nebulosity surrounding a white dwarf) in the constellation Vulpecula, at a distance of about 1360 light-years. It was the first such nebula to be discovered, by Charles Messier in 1764.
This is a beautiful and easy target for amateur astronomers. This picture is probably my best so far for this target!
Taken with partially de-filtered Nikon D7500 DSLR on Skywatcher Evostar 80ED and Barlow x2. Total exposure time ~12min (6x2min at ISO1600)
The heart of the Heart nebula revisited using the "natural palette" with special attention to the dark nebulas there.
It a complete rework of a previous image made on SHOrgb.
A total of 57 hours of integration and a lot of intermediate version on the process.
Still I think that I could obtain more details, but this will be next year (maybe :P ).

After a long hiatus from imaging due to ill-health and bereavement - oh and also hopeless weather, I managed this view of the afternoon moon in a very bright, sunny sky - amazing for here and indeed short-lived!
Imaged with a stock Nikon D5300 and a Skywatcher Esprit 120mm refractor. Thanks for looking!
Part of an HII (ionized Hydrogen) region in Cassiopeia the Pacman Nebula is a bright emission nebula.
Named for its resemblance to the video game character the nebula lies at a distance of around 9500 light years from earth.
This image captured in narrowband Ha light was acquired over 2 nights - 17 & 18th September in strong moonlight. After a prolonged period (seemingly never-ending!) of poor skies was glad to be out imaging again!
Hopefully will have some OIII and SII to add later.

Second completed image of 2021 and the first complete one from my local astronomy club's dark site, an hour and a half outside of Houston. We finally had the first clear new moon weekend of the year, and myself and many others in the club decided we had to take advantage of it. It was a beautiful night with no clouds and the dew kept at bay. Had to image something unique for galaxy season and I settled on Markarian's Chain in Virgo. I framed to to get as many individual galaxies as I could in one shot.

This beautiful comet is gone now, this may be one of my best shot of it as it was in its full glory!
Actually it was still getting closer to Earth but slightly fading. A slight green color started to appear around the nucleus. This can be noticed on this picture.
Shot with Nikon D7500 and Sigma 100-400. I stacked a few pictures tracked with Skywatcher Staradventurer.
A deep look at Omega Centauri ( NGC 5139 ) - by Mike O'Day ( 500px.com/MikeODay )
This image is an attempt to look deeply into the mighty Omega Centauri star cluster and, by using HDR techniques, record as many of its faint members as possible whilst capturing and bringing out the colours of the stars, including in the core.

My first try with the new chip that was put in the camera to replace the broken usb.
I was sent a QHY183M mono chip not the QHY183C Colour chip caused all sorts of problems in the end this camera getting found is now know as QHY183M but takes coloured photos. I lost a whole lot of time with the camera Changes and setting up. This is in effect only 33 shots But happy the way it came out.

NGC 300 is a spiral galaxy in the constellation Sculptor. It is inclined at an angle of 42° when viewed from Earth and is approximately 94,000 light-years in diameter, which is somewhat smaller than our own Milky Way. It has a very low surface brightness which made it difficult to image from our light polluted driveway.
Once again it seems that every image we do is plagued by issues. From crazy gradients, to focusing issues and tracking problems. This image was taken over two nights, but due to clouds rolling in and wind, we only managed a few hours in total. It was also extremely difficult to process due to its low brightness and we spent hours on this one. As it is summer time here at the moment and it really doesn't get dark for imaging until about 10.00pm, we can only get a few hours imaging of the very few clear nights we get. We really need to be getting greater than 10 hours on each target. Perhaps in the winter time.....
