That's what went through my head when I first stumbled across the Double Cluster h & chi Persei (a.k.a. NGC 869 & NGC 884) through my small, newly-bought amateur telescope. Of course, when I recently had the rare chance of observing this magnificent pair through 16" double-newtonian "binoculars", the view was even more stunning...
Also astrophysically, the objects are something quite rare, as they appear to be two young open clusters that are not only a chance alignment, but actually gravitationally bound siblings!
Still, it's a great and easy-to-find object (actually even visible as a faint smudge to the naked eye under reasonable skies) that's a pleasure to look at in anything from handheld binoculars to high-end amateur telescopes. And it seemed a fitting target to try out my new camera, a Canon M50 Mk. II, together with the 1000 mm f/10 Maksutov lens, which frames the two clusters just nicely. Plus, it's close enough to the celestial pole that I can actually use the 1000 mm focal length on the Star Adventurer for once.
I'm quite happy with the new cam, as it also has a much more powerful live view than my old trusty Samsung NX30, making object alignment soooo much easier if you can also see a few fainter stars on the display.

An attempt at the M81 & M82 couplet in Ursa Major (plus a cheeky little NGC 3077). I tried applying a 2x drizzle this time since these objects were very small in the raw image at 200 mm. Between the drizzle and compounded crop factors, this is maybe 6-8 times larger than off the sensor. Seemed to work ok, but some of the brighter (larger) stars look a bit blobby and weird.
As ever, the trick really is just to get as many exposures on a given area as you can. More exposures = better image. It'll reduce noise and get better drizzle. I just find it difficult to focus on getting just one image in a two or three hour night when the sky is SO BIG and I only get out so often! It would also be good to get a telescope or tracking mount, but that's another issue...one step at a time.

The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky.
M42 is located at a distance of 1,344 ± 20 light years and is the closest region of massive star formation to Earth. The nebula is estimated to be 24 light years across. It has a mass of about 2000 times the mass of the Sun.
Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula.

Picture I am finding post processing of astro images very hit and miss, and quite difficult, had another go at this one from the same stack file as previous, and tried very hard not to blow out the highlights, and this is the result, I think to an exstent astro post is very much to personal taste.

Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula.
The Orion Nebula is one of the most scrutinized and photographed objects in the night sky, and is among the most intensely studied celestial features. The nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. Astronomers have directly observed protoplanetary disks, brown dwarfs, intense and turbulent motions of the gas, and the photo-ionizing effects of massive nearby stars in the nebula.saved with settings embedded.
My last astrophoto of 2008. I love the winter constellations, especially Orion. So much to see. The winter Milky Way is not as bright as the summer Milky Way, but it's still beautiful.

Raw files stacked with DeepSkyStacker and postprocessed using Nebulosity, FITS Liberator, Photoshop and Lightroom.
First trial at using Nebulosity and FITS Liberator.
I didn't use anything particularly special to make this photo, I used a Canon 5DMkII with Samyang 14mm lens. I shot 10 photos, one after another, at ISO6400 for 15 seconds each. The lens was set to f2.8 and focussed on infinity. Each photo looked dim and uninteresting.
I then converted the RAWs to JPG (for memory consideration) and ran them through the free software DeepSkyStacker which puts the photos together and unrotates them so the stars don't 'trail'.
Then the combined image was processed in Photoshop to make the blacks black and whites white as the averaged photo has little contrast.
All this is from the data that I captured on location and it was in the Brecon Beacons in Wales! I'm impressed anyway :-)

Here's my other take at the moon just passing the Golden Gate of the Ecliptic on February 9, 2022. This close-up was taken with the Samsung NX30 camera and Samsung 50-200 mm OIS-III telezoom lens @ f = 70 mm and stopped down to f/6.3.
I really like how the Aldebaran and the Hyades cluster on the lower left and the Pleiades cluster on the upper right align almost perfectly with the moon. I'm also happy I managed to bring out some star colours, particularly bright orange-yellow Aldebaran.

A wide-field shot of the northeastern region of the constellation Cygnus showing the North America Nebula, a faint trace of the Pelican Nebula, and the nebulous patches surrounding the star Sadr (gamma Cyg). This image is best viewed in the Flickr light box (press the "L" key to toggle the light box and optionally click on the "View all sizes" menu item to see the image at its largest size).
Captured on October 19, 2011 between 10:07PM and 10:48PM PDT from a moderately dark-sky location using a Nikon D5100 DSLR (ISO 2000, 2 minute exposure x 13) and an AF Nikkor 50mm 1:1.8D lens set to aperture f/2.8. Tracking provided by a hand-driven, barn-door type mount (two boards, a hinge, and a screw you turn by hand). Image stack created with DeepSkyStacker using thirteen image frames combined with four dark frames (no flats or bias).
This is a full-frame image (uncropped) showing nearly the entire coverage of the 50mm lens on the Nikon DX-format sensor ("nearly" because about 3% of the angle of view was lost to remove field rotation within the stack of images).

Se fosse stato per il popolo Corso, a cui ho chiesto più volte un posto buio per potermi attrezzare e fare fotografie, questa foto NON sarebbe mai stata scattata :) mi spiace dirlo ma è un vero dispiacere vedere una cosi' bella isola popolata da gente così poco sensibile. Venite a trovarmi in Italia e vi concio per le feste ;)

I can't thank the people of Corse, I asked several times and gently a dark place to and to be able to take astrophotos, this picture doesn't would never have been taken! I'm sorry to say but it is a real disappointment to see such a 'beautiful island" populated by people so insensitive. Come and see me in Italy and we settle for the holidays ;)
