Bodes Galaxy (M81) and the Cigar Galaxy (M82) are known to form a beautiful pair of galaxies. M81 is strongly interacting with M82 and a third galaxy, named NGC 3077. This galactic trio was the target of this image.
M81 is a spiral galaxy about 12 million light-years away, in the constellation Ursa Major. It is the main galaxy of the 'M81 Group', which includes 60 Galaxies.
M82 is a starburst galaxy and a member of the M81 Group. It is it is about five times more luminous than the whole Milky Way and has a center one hundred times more luminous than our galaxy's center. The starburst activity is thought to have been triggered by interaction with neighboring galaxy M81.
NGC3077 is thr small galaxy on the left and a member of the M81 Group as well. Despite looking much like an elliptical galaxy, it is a spiral galaxy. It shows wispy edges and scattered dust clouds that are probably a result of gravitational interaction with its larger neighbors.

My first attempt at The Andromeda galaxy and its satellite galaxies - taken a few years back with a 400d with no astro mod (no removal of IR filter) attached to a telescope and tracking system, still came out very nicely. Taken from the Peak District, UK
I have a later attempt in my photostream - i think different aspects of the galaxy are picked up by the modded cam that can not be seen in this image. Interesting to compare - however this was a longer exposure than the modded cam shot was, so i feel with longer the modded cam would out perform this one.
Hard to believe this is an island universe containing hundreds of billions of stars, ancient and vast, lying 2.5 million light years away.
The Omega Nebula, also known as the Swan Nebula is an area of Hii in the constellation Sagittarius. It was discovered in 1745 by Philippe Loys de Chéseaux and Charles Messier catalogued it in 1764 as M17. It is about 6000 light years from Earth.
Capturing this image in narrowband brings out a lot more detail than that which is visable in broadband imaging.

NGC 3324 is an open cluster in the southern constellation Carina (the same constellation as our previous image of ETA Carina Nebula)
It is sometimes called the "Gabriela Mistral Nebula" due to its resemblance to the Chilean poet. It is approximately 7560 light years from Earth and is 6.754 million years old.
Once again, this was not our intended target for the night. Trying to resolve the guiding issues of the previous image of ETA Carina Nebula, I decided to remove the counter weight extention bar on the NEQ6 mount and add an extrea 5Kg weight. I slewed to the Resette nebula, calibated the guiding, and then did a 5 minute exposure. Although the result was better than the previous attempt at the Rosette, the stars were still eggy. I found that the tracking was getting gradually worse as I approached the meridian, but then improved the further I tracked away after the meridian flip. Perhaps balancing could be the issue, but I did find some backlash in the DEC, which I have now tuned out. I am now waiting for another clear night to test again and hopefully capture the Rosette Nebula in narroband.a

Nice steady seeing conditions on the evening of the 31/05 allowed me to image the 9 day, almost 70% illuminated, gibbous moon.
This is a lunar mosaic of individual section images taken with my ASI 224MC camera ( each 1304x976 pixels). These images were then assembled into the final image shown here using Microsoft ICE ( Image Composite Editor).
Imaged with a Skywatcher Esprit 120ED and a ZWO 224MC fitted with an IR cut filter.
Colours have been slightly boosted ( like to be as subtle as possible - hate gaudy over saturation!) to indicate different composition of lunar regolith.
Thanks for looking!
Yes, another M33! Inevitable at this time of year. 96% Moon!!
This was my first clear night in weeks but of course it coincided with a pretty much full Moon. Back in the year I bought an Altair Astro Tri-Band OSC filter which I had not had occasion to use so thought I'd give it a go. I couldn't find many examples taken with this filter so it was an unknown quantity. Quite pleased with the result.
A bit noisy and there were severe 'light pollution' gradients which required processing persistence to eradicate. APP's light pollution removal tool was excellent but not 100% so the remainder was removed manually in Affinity Photo. I thought processing would be quite involved but APP has a setting for this filter type which made it very straight forward.
Nice to know that I can now make use of those clear but Moon filled nights!!

My mount was polar aligned with SharpCap (what an amazing system for aligning). I then mounted my a7RIII and adapted Noct-NIKKOR 58mm f/1.2 Ai-S lens at f/2/8 to the top rail of my scope. I used SharpCap to achieve "excellent" polar alignment. I shot ISO 400, f/2.8 and 300" exposures. I stacked lights/darks/flats/bias frames in deepskystacker. I then processed the TIFF file in photoshop stretching the file, minimal cropping and I used Astronomy Tools Action Set to help bring back star color and to enhance the brighter star colors. Topaz Labs Sharpen and Denoise used as well.
M20 the Trifid nebula on the right and M21 open cluster on the left. M20 is both an emission and reflection nebula hence the two contrasting colours.
This is very low in the sky for me at the moment and I was only just able to get the telescope down lown enough!

I wanted to go longer but cloud piled in from the west. Of course by the time I'd done the flats and put everything away it was crystal clear again!!

The needle galaxy is an edge-on spiral galaxy in the constellation of Coma Berenices. The galaxy lies at a distance of around 40 million light years.
The galaxy's core bulges either side of the comparatively thin galactic disc which shows prominent dark dust lanes.
A fainter galaxy NGC 4652 is to the left of the Needle and lies at 75 million light years distance. A faint irregular galaxy IC 3571 lies just to the Needle's right.

Another aspect of the beautiful gibbous moon of the 4th April here.
Slight enhancement of subtle variations of colour on the moon's surface. These highlight the difference in mineral composition between the more iron rich regolith areas (brown coloured) and those regolith areas richer in Titanium (blue coloured).

Part of the Large Magellanic Cloud area but a part I have not taken before. N70 is the unmistakable Circular nebula top right. this was taken over two night to test out the New power supply box and how stable it is. The other effect of the power box was to reduce the number of cords that have to go from the top to the bottom to lessen the weight on guiding. the number of cord has reduced to two a far cry from the heavy load of the original 9. Now its fine tuning PHD2 to get the very small movement of guiding and better round stars.

This galaxy is found in the constellation of Coma Berenices. A spiral galaxy it lies about 17 million light-years from us but the most striking aspect is the dark band of absorbing dust.
This dark dust is partially in front of the galaxy's bright nucleus giving the galaxy its nickname of the "Black Eye Galaxy". It is also known as the "Evil Eye" or "Sleeping Beauty" galaxy. Rather like an eye with mascara applied!!
A type 2 Seyfert galaxy the whole system has a diameter of around 54,000 light-years.

After prolonged period of awful weather, which saw us miss out on fine weather in other parts, it was our turn at last to get some decent skies here so time to get the telescope assembled!
Both these galaxies are found in the Plough or Big Dipper constellation. This constellation is at its highest in northern skies in the spring, (though the plough is ciircumpolar) so this galactic pair is becoming well-placed for imaging here.
M81, also catalogued as NGC 3031, is a grand design spiral galaxy with well-defined and prominent spiral arms that extend clearly around the system. It lies around 12 million light-years from us.
M82 (to the right) is also known as the Cigar Galaxy is also at around 12 million light-years distance. This is a starburst galaxy (due to their fast rate of star production). Glowing red filaments of hydrogen gas can be seen emanating form the centre of the system.
Just partially creeping into the top of the frame is NGC 3077, sometimes known as the Garland Galaxy. This is a small, disrupted galaxy and is part of the M81 group. It is a Seyfert Galaxy having an active nucleus.
Just above M81 is a bluish-coloured irregular feature. This is Holmberg IX, a dwarf irregular galaxy that is a satellite galaxy of M81.
There are several other fainter galaxies within the field.
Imaged on the 28.02.22 with my Esprit 120ED and a ZWO 2600MC camera. The telescope was fitted with a Skywatcher 0.77x focal reducer.

This deepscape image shows the sword of Orion rising over a scenic mountain formation in central Switzerland. The famous Orion Nebula, the Horsehead and Flame Nebula and part of Barnard's Loop are coloring the sky in a stunning way.
Deepscapes are an attempt to take landscape astrophotography to the next level. This image is not a digital art collage of an unrelated sky and foreground, but a real alignment. A snowshoe hike with a mobile deep sky imaging rig to a carefully planned site on a mountain slope was required to capture this scene. Foreground and sky were captured back to back during the same night and from the same tripod position.
Capturing and processing the image required both deep space and landscape astrophotography techniques. The foreground and RGB color image of the sky were captured with an astro-modified Canon EOS 6D and a 200mm lens. The sky image was enhanced with 55min of H-alpha data captured with a cooled monochrome astrophotography camera through a narrowband filter.

La galaxia de Andrómeda, también conocida como Galaxia Espiral M31, Messier 31 o NGC 224, es una galaxia espiral gigante con un diámetro de doscientos veinte mil años luz y que contiene aproximadamente un billón de estrellas.[4] Es el objeto visible a simple vista más lejano de la Tierra.
The Andromeda Galaxy (/ænˈdrɒmᵻdə/), also known as Messier 31, M31, or NGC 224, is a spiral galaxy approximately 780 kiloparsecs (2.5 million light-years) from Earth.[4] It is the nearest major galaxy to the Milky Way and was often referred to as the Great Andromeda Nebula in older texts. It received its name from the area of the sky in which it appears, the constellation of Andromeda, which was named after the mythological princess Andromeda.
Being approximately 220,000 light years across, Andromeda is the largest galaxy of the Local Group, which also contains the Milky Way, the Triangulum Galaxy, and about 44 other smaller galaxies. Despite earlier findings that suggested that the Milky Way contains more dark matter and could be the largest in the grouping,[12] the 2006 observations by the Spitzer Space Telescope revealed that Andromeda contains one trillion (1012) stars:[9] at least twice the number of stars in the Milky Way, which is estimated to be 200–400 billion.[13]
NGC 5128 - Centaurus A is a galaxy in the constellation of Centaurus. It was discovered in 1826 by Scottish astronomer James Dunlop from his home in Parramatta, New South Wales, Australia. It is approximately 10–16 million light-years away,and is one of the closest radio galaxies to Earth. It is the fifth-brightest in the sky, but is only visible from the southern hemisphere and low northern latitudes.
At the center of the galaxy is a supermassive black hole with a mass 55 million times greater than the our Sun.
