M109, also known as the Vacuum Cleaner Galaxy (NGC 3992), is a barred spiral galaxy in Ursa Major, which lies approximately 83 million light years away, making it the most distant object in the Messier catalogue.
About half of all spiral galaxies are thought to be barred, including our own Milky Way. Barred spiral galaxies have a central bar-shaped structure surrounded by spiral arms. The central bar is a region of enhanced star formation, where new stars are born.
The diameter of M109 Vacuum Cleaner Galaxy (NGC 3992) is about 120,000 to 130,000 light-years, similar in size, to the Milky Way galaxy.
M109 earned its nickname "Vacuum Cleaner Galaxy" due to its appearance resembling a vacuum cleaner. (That's what 'they' say, whoever they are).
I got this image from about 4 hours observation using 2-minute exposures with my Celestron C11 telescope.

Have you ever felt you were being watched at night? The least sinister explanation may be explained by this picture.
These two galaxies are called the Eyes Galaxies. NGC 4438 is on the left and NGC 4435 is on the right. They are a pair of galaxies about 52 million light-years away in the constellation Virgo. The pair are members of the string of galaxies known as Markarian's Chain.
I took this image with over two and a half hours worth of 2-minute exposures using my C11 telescope on Saturday night.

IC 4665 is an Open Cluster in the Ophiuchus constellation. IC 4665 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year.
The celestial equator is an imaginary great circle on the celestial sphere that is in the same plane as Earth's equator, dividing the sky into northern and southern hemispheres.
I was using this object to set up and calibrate my guide scope for the night's viewing, which worked out nicely. The bright pattern of stars in this cluster also made a nice image for my first target of the night. The stars were so bright I only needed thirty 30-second exposures to capture this cluster and all those faint stars way in the distant background. The cluster is about 1400 light years away.
If you are interested and still reading this, IC stands for the Index Catalogue which is an update to the earlier NGC catalogue. IC 4665 is not a Messier Object and doesn't have a Messier Number.

6.10. Podyjska dark sky area
that evening I took a lot of risks and even though I threw away a lot of photos because of the clouds I fulfilled another dream Pleiades with clouds in interstellar space the photo is only over an hour of data to be exact 4440 seconds another more than an hour was spoiled by the clouds but still I am satisfied with the universe which is really not as dark place as people think.
I have to thank Martin for advice on how to process it as best and as honestly as possible even though we haven't met physically yet he really moved me a lot.
The night sky with its beauty and mystery has attracted me since ancient times, but when you just lie there, watch the stars above your head and your eyes gradually get used to the darkness you gradually see not only planes but also satellites, meteors and all that noise you are just amazed.
The universe doesn't have to rush anywhere. Seeing the peace even in the hustle and bustle helps a person but at the same time scares him how small he is compared to it.
Unfortunately, we also ruin this view with the light around us and that's why I'm glad I live where there are still relatively dark skies here and there.

The Perseus Double Cluster is a pair of star clusters located 7,100 and 7,400 lightyears away, but which appear right next to each other in the night sky.
The two clusters are h Persei, known as NGC 869 (the lower cluster in this image), and chi Persei, known as NGC 884 (the upper cluster). They are 5.6 million years old and 3.6 million years old, respectively. The two clusters are only hundreds of light years apart. Each cluster contains more than 300 blue-white supergiants.
In mythology, the Double Cluster represents the jewelled handle of Perseus’ sword, given to the hero by the gods, along with a shield and a helmet, to help him in his challenges.
Since this image only contains stars which are bright points of light I was able to use short exposures of 30 seconds to capture even the faintest of them. Any longer and the brightest stars would have been burnt out. This picture was formed by integrating 121 images taken thorough my William Optics Zenithstar 81 telescope.

It has been so long since I had a clear night that I thought I would try a target I have not looked at before. The result may not look as spectacular as some I have posted, but the detail in there is staggering.
In the constellation of Coma Berenices there is a cluster of thousands of galaxies. The centre is about 320 million light-years away and is flying away from us at the rate of about more than 15 million mph (24 million kph)!
The Coma Berenices galaxy cluster is one of the most populated galaxy clusters known. Scientists estimate that it contains as many as 10,000 or more members. Indeed, there are more individual galaxies in this cluster than there are stars visible to the unaided human eye on a clear, dark night.
I have posted another image which is not annotated so you can see the objects more clearly.
Most galaxies in the central part of the cluster are elliptical. Elliptical galaxies are the result of galaxy mergers. The two brightest members are NGC 4889 and NGC 4874, both of which are giant ellipticals. They are at least two to three times larger than our own Milky Way galaxy. Farther out from the centre are several spiral galaxies.
Above the centre of this image NGC 4921 is a large barred spiral galaxy. That galaxy is three times as large as the Milky Way.

With all these recent clear skies it has been time for mee to set up my trusty telescope. This image of the globular cluster M13 was taken with my big, heavy Celestron C-11 scope.
Messier 13, or M13, is a globular cluster in the constellation of Hercules. As a result it is sometimes called the Great Hercules Cluster and is considered the most spectacular globular cluster in the northern skies. About 145 light-years in diameter, M13 is composed of several hundred thousand stars, with estimates varying from around 300,000 to over half a million. Compared to the stars in the neighbourhood of the Sun, the stars of the M13 population are more than a hundred times more densely packed. They are so close together that they sometimes collide and produce new stars.
