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).

Not enough subs, and I need to work on coma, and the OAG caused a weird reflection. This is my first time capturing Soap Bubble!

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 :)

Last night was the first clear Moonless night for a while, so I drove an hour Southwest of Brisbane and took some test shots of some of the larger deep sky objects to see how my 100mm macro lens performs for astrophotography.
The Triangulum Galaxy (M33) is member of the Local Group of galaxies which is approximately 3 million light years away.
This image is 30 x 40 second exposures in a Star Adventurer Mini tracker, with the lens at f/4 and 3200 iso. Processed using DeepSkyStacker and Lightroom 5.

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 ;)

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.

When considering there was a full moon last night 26-4-2021, I am both supprised and pleased I managed to capture the Whirlpool Galaxy.
39 lights, 10@2min 10@3mins 9@4mins, 9darks, stacked in DeepskyStacker, post processed in Photoshop.
Nikon D750, Nikon 600mm prime with Nikon 2xteleconverter (1200mm) on a Skywatcher NEQ6-R-Pro mount, polmaster, Stellarium, PHD2 guide, DSLR control WiFi capture, bortle4.
The Whirlpool Galaxy, also known as Messier 51a, M51a, and NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus. It lies in the constellation Canes Venatici, and was the first galaxy to be classified as a spiral galaxy.
The Crescent Nebula (NGC 6888) is an emission nebula formed by a strong stellar wind from an extremely hot Wolf-Rayet star as it collides into and excites material that had been previously ejected from the star during it's red giant phase. Located approximately 5,000 light-years from Earth, the shell has a diameter of about 25 light-years in diameter.
Glowing at magnitude 7.4 in the constellation of Cygnus, although visible in smaller instruments, in large scopes under dark skies it appears as a fractured globe. Having had the pleasure of viewing this object in my friend's 20-inch, f/5 Obsession from the dark skies of the high desserts on the Snake River Plain in Idaho, it took on an incredible 3-D appearance (as one of my friends noted, looking like a partially constructed 'Death Star' from Star Wars :) ).
Image Details: The attached was taken by Jay Edwards at the HomCav Observatory on the evening of July 27, 2019 using an 8-inch, f/7 Criterion newtonian reflector and a Canon 700D DSLR tracked on a Losmandy G-11 mount running a Gemini 2 control system. This in turn was guided using PHD2 to control a ZWO ASI290MC planetary camera / auto-guider in an 80mm f/6 Celestron 'short-tube' refractor.
Shot at ISO 1600, it is a stack of 75 one-minute exposures (not including darks, flats & bias frames). Given the reasonable results I'm looking forward to trying this object sometime in the future using the same scope with one of our CCD and sets of narrowband filters in an attempt to pick up additional detail of the nebula's interior structure.
Stacked in DeepSkyStacker and processed using PixInsight and PaintShopPro, as presented here it has been cropped slightly, re-sized down to HD resolution and the bit depth has been lowered to 8 bits per channel.
The above was created from the series of images in this star trail shot: www.flickr.com/photos/steventheamusing/11240440045/
For fun I took the shots used in my "Life is a Beach Sometimes" shot (posted earlier), and masked off the foreground. I then ran them through DeepSkyStacker which is normally used for astroimaging. DSS wouldn't know what to do with the land.
There is a strong gradient left that I didn't remove... it's due to the light pollution from the nearby buildings and streetlights together with the mist and fog.
These shots were all ISO 1600, f/2.8, 20 seconds (which was too long for this purpose since it cause stars to be streaks rather than points of light).

Unfortunately the first evening with a chance to image this comet coincided with the brightest Full Moon of the year, so some subtle details are no doubt lost! Nevertheless, the comet’s ‘anti-tail’ can just be seen pointing towards the 5 o’clock position.

Orion Nebula in Orion - M42. 8 December 2010
Same old subject - sorry guys. Took this for a reason though - first light for my diy modded Nikon D70 (removed the infra red filter in front of the sensor). This makes the camera more sensitive to the wavelengths we want in astro images.

Cederblad 214, also known as Sh2-171, is an extensive emission nebula which is linked to Cepheus OB4 and is illuminated by the stars of the open cluster Berkeley 59. Vigorous star-formation processes are taking place inside it generating low-mass stars.
The nebulosity spans about 40 light years across and is located some 3000 light years away.
Within Cederblad 214 lies one of the hottest known stars (actually a binary system) designated as BD+66 1673. Its surface temperature approaches 45000K while its luminosity is about 100000 times that of the Sun.

In the Sharpless catalogue as SH2-206. Sometimes called the Fossil Footprint Nebula.
This is an emission nebula just under 11,000 light years away in the constellation of Perseus.
HII regions of space such as this are formed when the ultraviolet radiation generated by hot stars ionizes the surrounding gas, causing it to glow in the visible light.
You often hear tell that stars are made from dust & gas, well the dust is also affected by this radiation too. The radiation makes the dust glow in the infrared light.

I was testing the ED80 with a full-frame sensor. I think the result is pretty good, but with significant aberrations (coma?) in the corners. Please let me know if you have advice for correcting the coma. Eg, do I need more space between the reducer and the sensor, or less space?
