The inset of M67 is cropped from a different shot @ 300mm. Size is @ 100% out of my camera.

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.

This images is 50 exposures stacked with DeepSkyStacker, each 2.5 sec, f/2.8, 200 mm, 6400 ISO. (13 dark frames...also not enough darks)

- www.kevin-palmer.com - The Rosette Nebula is a target I've been wanting to photograph for awhile. But my last few tries have been unsuccessful because of the wind. The bright red nebula is found in the constellation Monoceros. On the lower left is the Christmas Tree cluster surrounded by faint nebulosity. The blue nebula doesn't even have a name other than NGC 2247.

This image is a stack of 14 2.5-minute, ISO 1000 exposures shot with the Nikon 180mm f2.8 lens at f/4.5. It was then cropped about 50%. I had intended to shoot more exposures but my iOptron Skytracker stopped tracking after awhile and I had to toss some images that were blurred from the wind. But I'm still happy with the results from an unmodified Nikon D750. I used the Astronomy Tools plugin in Photoshop to help bring out the colors and details.

M42, Orion Nebula. 21st January 2017. 23x 76s + 11x 121s, @ISO 400, Skywatcher 200P/DS + EQ5 Guided with PHD2. Stacked in DeepSkyStacker and processed with LR+PS

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.

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.

Taken a couple of nights ago from the back garden, a view of the star field at the end of the W shape of the constellation Cassiopeia, including the green glow from the gas surrounding Comet Jacques. Also visible is the background of stars in our Milky Way galaxy and two open clusters of stars. Messier 52 can be seen in the top centre and NGC 7789 to the lower right. There are two faint red patches of light - coming from glowing clouds of hydrogen, NGC 7822 close to the left and about a third of the way up from the bottom and to the top right of the cluster Messier 52 is NGC7635, also known as the bubble nebula.

In total there were 40 exposures of 20s used, combined in DeepSkyStacker and the image corrected in FitsWork to flatten the background.

Description:

One of the most prominent, largest, brightest and well known nebulae in the sky is the Lagoon Nebula, which is a favourite target of amateur astronomers with modest telescopes.

From Wikipedia: "The Lagoon Nebula ... is a giant interstellar cloud ... classified as an emission nebula and as an H II region. [It] was discovered by Giovanni Hodierna before 1654 and is one of only two star-forming nebulae faintly visible to the eye from mid-northern latitudes. Seen with binoculars, it appears as a distinct oval cloudlike patch with a definite core. Within the nebula is the open cluster NGC 6530.

The Lagoon Nebula is estimated to be between 4,000-6,000 light-years away from the Earth. In the sky of Earth, it spans 90' by 40', which translates to an actual dimension of 110 by 50 light years. ... The nebula contains a number of Bok globules (dark, collapsing clouds of protostellar material), the most prominent of which have been catalogued by E. E. Barnard as B88, B89 and B296."

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).

I prefer this version. Slightly wider crop, and the dust lanes (what there is of them) are better defined (the outer is just visible in this version). Also doesn't look quite as flat. Minimum of noise reduction used as I've abandoned my usual 1600iso in favour of 800 (the D70 is a lot happier with that) :) And I didn't use any masking on this version, which I'm very pleased with - usually I mask everything :)

My first session with the 12" Newtonian since May, and unfortunately not very successful due to the aberrations (coma and tllt) that distort the stars (I've cropped the worst of it out). It seems to be worst when I image objects high in the sky, while those closer to the horizon have better-shaped stars.
