Mosaic of the pelican nebula (top half) found in Cygnus. A relatively bright emission nebula that sits right next door to the North America nebula, near the Star Deneb. Taken in hydrogen alpha wavelength. I joined two panels up for this image and stitched them in microsoft ICE freeware.

Someone recently pointed out the cool sinister looking face in the middle that has the two brighter stars for eyes. :)

Shot with my 80mm refractor and new/old CCD atik16hr through an astronomik ha clip filter, attached via a 2inch adapter and nosepiece.

9x 10min each panel.

I have the cluster bug :)

Spent a good amount of time recently testing a bit of kit that effectively converts my EQ5 to a Goto, and now using EQMOD in conjunction with PHD for guiding. Working well, and for £90 (and in the true spirit of budgetastro) I'm more than pleased :)

Found this cluster while I was zipping around the heavens playing with the Goto, and fell in love with it. M35, aka NGC 2168 in the foreground, is about 2.8K light years away, quite young at 150m years (hence the blue stars) and contains about 2500 stars. NGC 2158 (above right of M35) is about 10K lights years away and is ten times older than M35 (hence the orange stars). It contains many more stars than M35 but in roughly the same volume of space (30 ly wide), so looks more like a globular cluster. Nice contrast :)

Continuing our seemingly never ending series of clear nights, this is the North America Nebula, featuring The Wall. Noisy, but done in one session as the dark isn't long enough at this time of the year, and I don't have the energy to do another session. Also the sensor was running at 31c, which is a bit warm :)

當彗星遇上深空天體

近年彗星拍攝變得熱鬧，尤其是近兩年的 PANSTARRS 及 LOVEJOY 是十分容易捕足得到的，還能夠與在不同的深空天體掠過，令萬年不變的深空天體畫面多了一點變化。今年初就是 LOVEJOY C/2014 Q2 的熱鬧拍攝日子，剛好在昴宿星團與加州星雲附近飛過，用上廣角鏡頭也能輕易拍攝，尾巴長度數以十萬公里以上，十分壯觀。

今年另一顆彗星 CATALINA C/2013 US10 將會是另一個熱門目標，12 月至 1 月期間將可達 5 至 6 等亮度，1 月中更會跨過 M101 星系，令 M101 變得不再狐獨。喜歡拍攝深空的你，相信不會錯過吧！

BBC: 100 greatest films of the 21st Century.

The best that cinema has had to offer since 2000 as picked by 177 film critics from around the world — редакторы BBC составили Топ 100 лучших фильмов вышедших с 2000 по 2016, опросив 177 кинокритиков

нет времени объяснять, почему у британских учёных 21st Century начинается в 2000, а не в 2001 (ниже написано), почему на сотом месте у них сразу 3 фильма и нет ничего после 2016 (он составлен осенью '16), но в любом случае было интересно взглянуть, плюс ниже я сделал Alt Top 150, не благодарите.

For the purposes of this poll we have decided that a list of the greatest films of the 21st Century should include the year 2000, even though we recognise that there was no ‘Year Zero’ and that 2001 is mathematically the start of the century. Not only did we all celebrate the turn of the millennium on 31 December 1999, but the year 2000 was a landmark in global cinema, and, in particular, saw the emergence of new classics from Asia like nothing we had ever seen before.

#прояснилось, половину из того что они понаписали я не смотрел, что-то в их топе кажется переоценённым (но кое-что отметил на будущее), с другой стороны — классно, что кто-то генерирует нечто подобное, стимулируя сделать свою версию и «вспомнить всё», хотя очевидно, что все эти топы и места условны и меняются со временем, у Линча, кстати, мой топ 5 таков: Twin Peaks 1990-91; Lost Highway '97; Dune '84; Blue Velvet '86; Eraserhead '77.

This was shot from my backyard in Long Beach, CA. Whenever I target deep sky objects from my light polluted home skies, there are always significant gradients to deal with in the final image. With this particular data, that is made worse by the image being a mosaic. I shot this in March 2017, and over the past two years, I think I learned enough to minimize their effect. M53 is in the upper right, and NGC 5053 is in the lower left.

Each panel is a stack of 120 s exposures shot with a Celestron Edge HD 9.25" at f/2.3 with Hyperstar and an Atik 314L+ color CCD. Initial pre-processing in Nebulosity, stacking and initial processing in PixInsight; final processing in PS CS 5.1.

On my last nightscape photography trip to Taralga, Australia, I was able to get some shots of the Milky Way’s core region not long before it set over the southwestern horizon. Once that favoured area of the heavens was–literally–out of the picture, I turned my attention to photographing some of the other galaxies that are visible here in the Southern Hemisphere.

I recently posted one of those images, containing the Large and Small Magellanic Clouds, which are dwarf galaxies travelling through space with our own Milky Way galaxy. As well as those relatively-close massive collections of stars, planets, dust, gas and asteroids–and the odd black hole or two–there are a few other “islands universes” that are visible to naked-eye observers. I photographed two of these, the Andromeda Galaxy and the Triangulum Galaxy, as they hung low in the northern sky.

Known in astronomical catalogues as “M31”, the Andromeda Galaxy sits around 2.5 million light-years from our position in the “Local Group” of galaxies. M31 is visible in my photo as a fuzzy-yet-distinct bright disc mid-way down the shot, and about one third in from the left. If you look up to the right, in the one o’clock direction from Andromeda, there’s a much smaller blur of light showing the position of the Triangulum Galaxy. Aka “M33”, this galaxy is nearly 3 million light-years away in space. The Milky Way, M31 and M33 are the three largest galaxies, respectively, in the Local Group.

This image was stacked from ten single-frame photos, each of which I shot with my Canon EOS 6D Mk II camera, a Yongnuo 50mm f/1.4 lens @ f/1.4, using an exposure time of 8 seconds @ ISO 6400.

Little less brutal, and easier on the blue. Also, I used lens correction in the previous version to compensate for the lack of flattener. That distorts the entire image though, and made the galaxy a little wide of girth! Better in this version I think (if you don't look at the corners) :)

山上的七姊妹

提起深空拍攝十居其九會認為是很困難的，還要花上許多時間去拍攝及處理，加上這些深空天體再過數千年也不會有變化，只要有不錯器材，加上天氣及時間的許可，很容易便會得到一張美麗的深空天體相片。想要有變化就要像風景一樣加入不同地景去配合，令深空天體構圖不再死板。

往時就曾經嘗試多個不同的深空及地景組合，但只屬於 Wildfield 方式拍攝，深空天體不太突出，被地景搶了風頭。今次就嘗試用上 135mm 鏡頭找尋簡單地景，深空天體也可以變得大一點。剛好在陰那山的第一晚設定好器材後，便看見七姊妹星團在飯堂上的水庫探頭而出，用上 5 分鐘時間將其捕獲下來，再花上 30 秒地景，簡單地在 Photoshop 處理一下便得到這張「山上的七姊妹」。

I managed to add 3 hours to my previous version of this on Saturday night, but that has little to do with the above result. This is my first attempt at collaboration with my good friend Dave Williams (whom I have never met, as he lives in the frozen northern wastelands known as Manchester). Dave works in NB, and provided Ha, which I added as a luminance layer (after trying a few other techniques without success), and this is the result. Now I'm fully aware that what you can see above is predominantly luminance, with a bit of RGB thrown in to provide character, so Dave very much deserves most of the credit for this image. However, as he's not on Flickr, I'm happy to accept it :)

This is also my first attempt at combining Ha with RGB (albeit as luminance), and It makes my previous version look a bit sick :)

Three clear nights on the bounce - whatever next?! :)

Took advantage of the weather to give this a really good crack, something I've been waiting to do since the arrival of the ED80. This is full frame, so the focal length is ideal. As near as dammit 8 hours total exposure, made up of various sub lengths and iso settings. The variation in iso seems to improve the overall noise in the final tif, so I was able to stretch this a little further (some would say too far!). Not sure if it's a little too contrasty - all a matter of personal taste I suppose. Overall, I'm very pleased with this :)

After a few cloudy and foggy nights, I finally had the opportunity to get to know my new digital telescope “ZWO Seestar S50 Smart Telescope” better and try it out with excellent visibility.

The constellation of Orion is one of the most beautiful and striking winter constellations. It contains a star-forming region and many interesting celestial objects. The most famous are probably the Horsehead Nebula and the Orion Nebula.

Nach ein paar trüben und nebligen Nächten gab es nun endlich wieder die Gelegenheit, mein neues Digitalteleskop „ZWO Seestar S50 Smart Teleskop“ näher kennenzulernen und bei hervorragender Sicht auszuprobieren.

Das Sternbild Orion ist eines der schönsten und auffälligsten Wintersternbilder. Es enthält ein Sternentstehungsgebiet und viele interessante Himmelsobjekte. Die bekanntesten sind wohl der Pferdekopfnebel und der Orionnebel.

Taken with a TMB92L, Canon T3i DSLR, Orion SSAG autoguider and 50mm guidescope, and Celestron AVX mount. Consists of 32 180-second light frames and 28 180-second dark frames, all at ISO 400, as well as 31 flat and 25 bias frames. Captured with BackyardEOS, stacked in DeepSkyStacker, and processed in Photoshop. Diffraction spikes added with StarSpikes Pro.

Another Messier object to check off the list, and the only one in Capricornus. The star to the left (east) is 41 Cap. If you look closely, you will see some tiny (very distant) galaxies that share the view with this globular cluster.

NGC 281, often referred to as the Pacman Nebula due to its resemblance to the character from the video game "Pac-Man," is an emission nebula located in the constellation Cassiopeia. It lies about 9,200 light-years away from Earth. NGC 281 is part of the Milky Way galaxy and is a region of active star formation.

Taken - after a recording time of 32 minutes - with my new digital telescope “ZWO Seestar S50 Smart Telescope”.

The Orion Nebula or Great Orion Nebula (also known as Messier-42, M42 or NGC 1976) is a diffuse nebubula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion, and is knoes as the middle "star" in the "sword" of Orion. It is one of the brightest nebulae and is visible to the naked eye as a bright spot in the night sky.

De Mairan's Nebula (Messier-43, M43 or NGC 1982 is physically part of the Orion Nebula and looks like a sphere, and is separated from Orion Nebula by a dense (black) lane of dust known as Northeast Dark Lane.

At the top left you can already see the Running Man or Ghost Nebula (Sh2-279, S279 or NGC 1977) - still quite dark.

The photo consists of many individual images, each exposed for 10 seconds over a period of 32 minutes and automatically stacked by the Smart Telescope. This suppresses image noise and reveals more details - the longer the recording time, the clearer the result.

I then edited the resulting photo with Luminar Neo and jpg-Illuminator.

Aufgenommen nach einer Aufnahmezeit von 32 Minuten mit meinem neuen Digitalteleskop “ZWO Seestar S50 Smart Teleskop”.

Der Orionnebel oder Große Orionnebel (auch bekannt als Messier-42, M42 oder NGC 1976) ist ein diffuser Nebel in der Milchstraße, der sich südlich (unterhalb) des Oriongürtels im Sternbild Orion befindet und als mittlerer „Stern“ im „Schwert“ des Orion bekannt ist. Er ist einer der hellsten Nebel und am Nachthimmel mit bloßem Auge als heller Fleck sichtbar.

De Mairans Nebel (Messier-43, M43 oder NGC 1982) ist physikalisch Teil des Orionnebels und sieht aus wie eine Kugel. Er ist vom Orionnebel durch eine dichte (schwarze) Staubspur getrennt, die als "Northeast Dark Lane" bezeichnet wird.

Oben links kann man bereits - noch recht dunkel - den "Running Man" oder Geisternebel (Sh2-279, S279 oder NGC 1977) erkennen.

Das Foto besteht aus vielen Einzelbildern, die während eines Zeitraums von 32 Minuten jeweils 10 Sekunden belichtet und durch das Smart Telekop automatisch "gestackt" (gestapelt) wurden. Dadurch wird das Bildrauschen unterdrückt und es werden mehr Details sichtbar - je länger die Aufnahmezeit, desto klarer also das Ergebnis. Danach habe ich das so entstandene Foto mit Luminar Neo und jpg-Illuminator nachbearbeitet.

I uploaded a version of this a month or so back that was supposed to be a combination of this year's data and last year's. Turned out it wasn't - what I got out of DSS was exactly last years data - it completely ignored this year's. DSS playing silly buggers.

This, on the other hand, is the combined data - 2 hours 23 minutes of 60 second subs. This is about three quarter frame, and rotated to provide a different angle - change is as good as a rest. Nice and small and cute :)

I was browsing through some old captures, and then find this one. Why did I forget to publish it?

I don't know! Well, better later than never.

This was my first capture using my T6i, back on July 9, 2020.

I remember now, why I did capture the Crux again. My hope was to compare, side by side, my old Nikon D5000 and the "new" Canon T6i. Well, my D5000 served me well for a long time, but now it needs to retire. :)

My Nikon D5000 have a serious issue with its sensor. On the right corner and top of the image we can see it failure. A region of the sensor which does have a lack of sensitivity.

First I though it was a "flat frame issue", but it's not. Darks and bias doesn't help.

Only after a carefully processing I'm "ok" in posting this picture. But my Nikon D5000 is old, and I'm not happy to say that it needs to retire.

I found an empty piece of plastic the other day, on which I had no hesitation in slapping a modded Canon 500D, purchased at a very reasonable price from James Stannard here. There then followed a bit of a learning curve - having been used to a Nikon - which has taken up the best part of two weeks. But I got there in the end :)

This is another collaboration with my good friend Dave Williams from the northern wastelands, who generously donated large portions of Ha, used as luminance.

I will now spend some time trying to breathe life into my Nikon D70 so that I can inflict some considerable pain on the thing, before I eventually kill it - slowly.... :)

The complete mosaic with this globular cluster and its surroundings can be viewed at flic.kr/p/2m84gRJ

Globular cluster M4 is the closest globular cluster to the Earth. It is situated in a very colorful part of the sky known as the Rho Ophiuchi dust complex. You can get a hint of the colors in the background of this image. This is part of the larger mosaic I am working on constructing around Antares. This is proving to be a good bit more challenging than the one near Sadr ( flic.kr/p/tYxubt ), mostly due to so many bright stars in the region. The gradients from the colors of interstellar dust and gas is also a challenge to work with.

The panels of the mosaic are stacks of 90 s shots. This portion includes 3 panels. There are 4 in the i Sco mosaic posted earlier (available at flic.kr/p/2gbsUqJ ). The 90 s shots were taken with a guided Celestron Edge HD 925 at f/2.3 with HyperStar and an Atik 314L+ one shot color camera. Preprocessing in Nebulosity with flats, darks, and bias frames; stacking, compiling the mosaic, and initial processing in PixInsight; final touches in PS CS 5.1.

Image center (J2000) is at

RA 16h 22m 57s

DEC -26° 23' 1"

The image spans about 1.5° x 1.0°.

Very early this morning, I had an epiphany, and made a big discovery.

As most of you know, I own a 10" Meade LX200 telescope. The focal ratio of the telescope is f/6.3, which puts it about 15-20 percent optically faster than a standard f/10 Schmidt-Cassegrain.

For a couple years, I've had an f/6.3 focal reducer/field flattener for a smaller f/10 8-inch Meade LX5 telescope I also own.

I decided to experiment - and in the process of doing so, I made my 10" LX200 optically faster by 50%. What does this mean?

I now have significantly more light gathering power, at a small cost. The focal length is halved from 1600mm to 800mm.

Not only that, I can shorten my exposure time by half!

This is the first result: Messier 42 - AKA The Great Orion Nebula.

10x5 seconds for the core

20x30 seconds for the outer fringes.

15x5-second dark calibration frames

It would've taken me about twice as long to gather the data to produce this image!

It is cataloged as Sh2-103 (W78 as a radio source), but its parts are identified in the most widely used NGC catalog: the eastern part is NGC 6992 and 6995, while the westernmost part is NGC 6960.

To capture it almost in its entirety, I created a 2x2 mosaic. Each panel took about 5.5 hours of integration, with 10-minute guided exposures using an Antlia ALP-T 5nm dual-band filter for the nebula, and one hour of 60-second exposures without filters for the stars. 150/600 Newtonian telescope with Tecnosky 0.95x corrector, Tecnosky Vision 571C camera, Eq6-R Pro mount, Pixinsight processing.

Taken with digital telescope “ZWO Seestar S50 Smart Telescope” in Mosaic/Framing mode with 62 minutes (372 x 10 seconds) exposure time edited with Luminar Neo, Neat Image and Jpg Illuminator.

I would have liked to expose for longer, but then the high fog came.
