Andromeda galaxy shot from my driveway on a dark autumn evening. This is the only benefit I see from changing the clocks back... earlier night sky viewing. 5 images (300mm - 30 seconds each) on an iOptron SkyTracker stacked in DeepSkyStacker to reduce noise.
Manually guided for 7 x 7-minute exposures at ISO 1600, f/6.25. Modified EOS 600D & Sky-Watcher ED80 refractor, piggybacked on a Celestron C8 telescope for guiding.

Hi,
Here is one of my first astrophotograph of the deepsky I took at prime focus of my newtonian telescope with my canon T3i camera (unmodded)
It is a 10-image-stacked picture of 30 seconds each.
Both staking and processing were made by a friend using PixInsight sofware. Thanks to him :)
It is actually an update of my previous version inwhich I had used Deep Sky Stacker freeware and lightroom. Click here.
So, how to find the difference between PixInsight and DSS/Lightroom ?
We clearly see the powerful process of PixInsight !
Thanks for reading ;)

Comet Leonard is the astronomical event of the year, discovered in January 2021 is located at 35 million kilometers from our planet. As an example, the moon is at 384.400 km.
In its elliptical path with our Sun, it is estimated that it visits us every 40.000 years and to observe it you have to get up early, at 4am. It is not visible to the naked eye, but it can be seen with binoculars at its closest to the earth, which is estimated for December 12.
The photos are taken with an equatorial tracking mount, similar to those found in observatories, to increase the exposure time and prevent stars from looking like traces. Different shots of 30s, 50s and 60s are shot with different ISOs which are then stacked to bring out the tail and details.
El cometa Leonard es el evento astronómico del año, descubierto en enero de 2021 se encuentra a 35 millones de kilómetros de nuestro planeta. Como ejemplo, la luna se encuentra a 384.400 km.
En su trayectoria elíptica con nuestro Sol, se calcula que nos visita cada 40.000 años y para observarlo hay que madrugar, levantase a las 4am. No es visible a simple vista, pero si se apreciara con unos prismáticos en su máximo acercamiento a la tierra, que se estima para el 12 de diciembre.
Las fotos están obtenidas con una montura de seguimiento ecuatorial, similar a las que tienen los observatorios, para aumentar el tiempo de exposición y evitar que las estrellas se vean como trazos. Se lanzan diferentes tomas de 30s, 50s y 60s con diferentes ISO que luego se apilan para resaltar la estela y los detalles.

The Horsehead Nebula is approximately 1500 light years from Earth. Also known as Barnard 33 in emission nebula IC 434, also called as 'the Flame', is a dark nebula in the constellation Orion. The nebula is located just to the south of the star Alnitak, which is farthest east on Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex. (from from wiki).

Located 6,400 light years away in the constellation of Orion, the Monkey Head is an emission nebula and home to the open star cluster NGC 2175.
The nebula acts as a womb for new stars to be born. Those new stars then radiate such immense energy that blasts in to the surrounding gas and dust that makes up the nebula. This has the effect of not only clearing away the surrounding nebula from the newly born star but, causes the gas and dust in other areas to be pushed together. When enough of this material is pushed together it allows gravity to take hold and pull more and more of it in. When enough of it is pulled together there's a good chance another star will be born.

There's a few galaxies in this. Apart from all the chunky ones, there are loads of little fuzzy ones as well. Cool. Not quite Hubble Ultra Deep Field, but not bad from my back garden :)

A first attempt at photographing the Orion nebula. Using a focal length of 135mm, I was able to also capture the Horsehead and Flame nebulae in the frame. You can just make them out towards the bottom right of the image. Still lots to learn!

Also known as the Beehive cluster. M44 lies at 577 light years from Earth in the constellation of Cancer and spans about 15 light years across. In total there is estimated to be over 1,000 stars associated with this cluster. At around 600 million years old this cluster is quite young, when compared to our Sun's 4.5 billion years.

Yet another collaboration between Dave Williams (Ha) and myself (RGB). After a month without a single usable clear sky, we finally got one, so I quickly read all the user manuals for my kit again and got out there. Freezing cold, but I suffered in silence (as there was no-one else there) and soldiered on. Managed 2 hours of 3 minute subs and combined Dave's Ha as luminance, as before.
I may add more RGB as and when the opportunity arises (hopefully this side of Christmas) but for the time being I'm quite pleased with this effort.

Following comments made by Jean Jacquinot on my last iteration of this thing, a committee meeting was convened, and the man from the frozen north agreed that some detail had been lost. It was decided that a reprocess was in order, and this has now been actioned. Above is the result :)
Does Flickr sharpen images when you upload them? It certainly seems to. Anyway, a full reprocess, colour tweaked in places, etc. etc. Better I think. Thanks to Jean for pointing out my previous oversight :)
Last iteration here, for comparison.
I now regard the horsey in the same light as Andromeda, so I'll say goodbye to it until next year :)

Die Milchstraße, auch Galaxis, ist die Galaxie, in der sich unser Sonnensystem mit der Erde befindet. Entsprechend ihrer Form als flache Scheibe, die aus Milliarden von Sternen besteht, ist die Milchstraße von der Erde aus als bandförmige Aufhellung am Nachthimmel sichtbar, die sich über 360° erstreckt.
This is a view of IC 1795 - The Fish Head Nebula, and is part of a huge star forming system of gas and dust located along the Perseus spiral arm of our Milky Way galaxy. The nebula is located in the constellation Cassiopeia approximately 6000 light-years from the Earth and is adjacent to the much larger Heart Nebula. This image was designed around the Hubble Palette of colors, splitting my image into artificial Sulfur II, Hydrogen Alpha, and Oxygen III channels. The image was then reassembled giving these hues that are typical of images from the HST.

Yet another clear night - whatever next?! :)
I did another 4 hours on M33 last night, only to discover at the end that the dew band wasn't working - 4 hours wasted, more or less. Not to be deterred, and with Orion waving at me invitingly, I had a go at good ol' long face. The ED80 works miracles on this, compared to the 200p :)

Right, I'm officially sick to death of Andromeda! This is now 16 hours of varying sub-lengths and ISO settings, and I've reached the point where my skies are going to yield no more. Quite depressing to think that 16 hours here produces the same result as perhaps an hour under dark skies - so this is my final attempt ;) (Wrong!). Better processing than the last shocking effort I think - a little more subtle, and some fainter detail evident (and some detail less evident as the contrast has been turned down a bit!)
Having spent a fortnight thinking about very little else, I can now get on with my life :)

Also known as IC 434 and Barnard 33.
The horsehead nebula is approximately 1,375 light years away in the constellation of Orion. A very difficult target to find in a telescope, it's possible with a large aperture using specialist filters. A camera that can pick up Ha it's much easier :-)
IC 434 lies on Orions belt close to the flame nebula with the very bright star Alnitak (just visible lower left) separating them.

Messier 67 is an open cluster in the constellation Cancer. This open cluster was photographed on March 9, 2015 using ten one-minute exposures using my standard astrophotography setup.
The images were "stacked" together using the software package DeepSkyStacker. The final image was edited using Corel PaintshopPro software.
The open cluster, at the time of this writing, was located near the planet Jupiter and the Beehive Cluster (Messier 44). At magnitude 6.1, you will need a pair of binoculars to see this ancient open star cluster.

I haven't had a chance this summer to photograph my favourite astronomical subject. So, when the conditions called for clear skies, no moon, early end to twilight and a rural location my Muse beckoned.
The Fossil Footprint Nebula.
Discovered in 1790 by William Herschel NGC 1491 can be found in the constellation of Perseus at a distance of approximately 11,000 light years from us.
Known as a HII region. This type of nebulae is caused by ultraviolet radiation from the hot young stars being born within ionizing the surrounding nebula, which cause it to glow in visible light allowing us to see it.
