Stack of 16 images taken with a 1953 Leica 9cm Elmar f/4 lens mounted on my 2011 Olympus E-PL2: camera on tripod, with no tracking.

The nights are starting later and later, and Orion is setting earlier and earlier, so I might not get too many or any more chances to shoot the majestic nebula. This image was particularly hard to get, as I was shooting from my building's back yard in what's, for all intents and purposes, downtown Ottawa, where light pollution, especially near the horizon, is substantial, hence the background noise as I try to extract as much detail out of the shots as I could.

Oh well, just you wait, I'll get you next Fall, Orion!

The Flaming Star Nebula (IC 405) as seen in the back yard. This is a sum of 72 lights over 3 nights in November, 2012. Each light is 10 minutes at 400 ISO.

Used the Stellarvue SV4 refractor with the SV F6 flattener.

Taken with the full spectrum modified Pentax K10D camera. Used a Peltier cooler on the camera with temperatures between 5-10C. Most subs were at 8C. Baader Moon and Skyglow filter used with UV/IR filter stacked on two nights. On the final night, I used an IDAS LPR filter.

The frames were calibrated using Maxim with 256 bias frames, 95 darks, and 2, 21, or 53 flats depending on the day.

Stacked using DSS to make the mosaic. PP with PixInsight for crop, DBE, MT, ADCNR, and histogram stretch. Exported to LR3 for final touch and upload.

I'm happy with this shot. I would have liked to have better framing, but as it stands this is not bad for being captured in a suburban location. There was flexure in the RA direction. I'm working to solve this problem.

Tewkesbury, Québec, Canada - Automne 2016

Here is a very special picture, which requested a bit of luck to get the aurora and time for the star trails. The view is from the church in Tewkesbury, north of Quebec City. The northern lights have been slow to show up. From the beginning of the evening, I started a time lapse. My camera captured a photo every 20 seconds from 9:30 pm until 2:00 am. By stacking the pictures, I got the circular star movement effect caused by the rotation of the Earth.

---

Voici une photo bien spéciale, qui a demandé un brin de chance pour avoir les aurores et beaucoup de temps pour les trainées d'étoiles. La vue est celle de l'église à Tewkesbury, au nord de Québec. Les aurores ont mis du temps à se pointer le bout du nez. Dès le début de la soirée, j'ai démarré un timelapse. L'appareil a donc capturé une photo toutes les 20 secondes de 9h30 jusqu'à 2h du matin. En empilant toutes les photos, nous obtenons l'effet circulaire produit par la rotation de la Terre. Au centre de ce cercle, nous retrouvons l'étoile Polaire.

À bientôt,

Fred

Psychic TV & Cult Of Youth @ Club Zal, SPb, Russia, 30.10.2016

Psychic TV полностью сыграли новый альбом Alienist (2016), где внезапно есть каверы на The Creation - How Does it Feel To Feel? и малоизвестного у нас (точнее вообще неизвестного) Harry Nilsson - Jump Into the Fire (этот Гарри уже умер, но считается пионером экспериментов с overdub).

Начали концерт флагманы Sacred Bones — Cult Of Youth, и они мне нравятся до сих пор, ребята не растеряли бодрости духа, например — спасибо что вернулись, надеюсь они в процессе реализации новых идей, и скоро мы увидим их очередную пластинку.

Между прочим, та самая Jenny Hval выпускается тоже на Sacred Bones, и она их новый локомотив.

Программу PTV в СПб можно условно поделить на две части — сначала Alienist, и отдельно я бы отметил четыре последних песни, по 10 минут (всё как я люблю), начиная с Greyhounds of the Future — это тот самый трек, когда котек остаётся на сцене совсем один, и в середине песни начинает шаманить с наложениями и лупами. Очень люблю и эту их бесконечно длинную балладу Burning The Old Home, а-ля The Doors. На финальный трек (Suspicious) к PTV вышли Cult Of Youth, и на этой позитивной ноте двухчасовой шабаш завершился — мне кажется всем понравилось.

Жаль PTV не сыграли Silver Machine (Hawkwind) / Mother Sky (Can), как на Roadburn 2013, или SKIF 2012, и видимо в этой жизни я так и не дождусь живого исполнения Godstar. Супераншлага у нас не было, зал заполнился процентов на 70 (скорее меньше), при цене билетов ~2500. Поначалу были небольшие траблы с саундом, что удивительно для этого места, которое я всегда хвалил — и у PTV и у COY что-то коротило, насколько я понял, из-за штекера на полу, но специально обученные люди незаметно вышли на сцену, и к счастью в итоге всё починили.

Ребята выставили разный мерч, но мне больше всего понравилась худи OS звукаря PTV — с отличным лого Psychic TV, но он так и не догадался мне её подарить. Кстати, в Sala Apolo Barcelona, 30 мая 2016, их лайв был сильно короче, а Neil Andrew Megson с тех пор слегка похудел — это наверное хорошо, так что пожелаем ему успехов и держаться там!

The North American Nebula is a red emission nebula situated in the constellation Cygnus. Its name comes from its uncanny resemblance to the continent of North America. It is an area of new star formation in our Milky Way Galaxy. The nebula is composed of hydrogen gas and interstellar dust. It glows red because nearby stars stimulate the hydrogen gas to glow with their intense radiation from those stars striking the gas.

The nebula is located about 1,600 light-years from Earth. The distance across the widest span of the nebula is about 100 light-years. This is an enormous object considering the comparison that the distance from the Sun to the nearest star is about 4 light-years.

A Canon XSi camera with a Canon EF 200mm lens set to f/4 and an Astonomik Clip LPS filter were used to capture the image. The camera was set at ISO 1600. The camera was mounted on an Astrotrac computerized tracking mount. 60x60sec Lights were taken. No Flats were used. Post-processing was accomplished with DSS and GIMP.

Elephant’s Trunk Nebula (IC1396), 08/18/2020

This was a fun night and an unexpected result. I took my equipment out to my favorite dark sky location to camp and capture photons. I was looking forward to showing off my hobby to my wife and some friends who were camping as well. I got my gear setup and took my first capture, but the frame was very faint and unexciting. Kind of boring. Oh well. Everything else was going well so I decided to stick with it and see. The next day I did a quick stack and process and DAMN there was a ton of detail there after all! I did not quite get the framing right but that only means I have a reason to try this one again.

I don’t know how someone saw an elephant trunk when looking at this but hey you discover it, you get to name it I guess. It is found in the constellation of Cepheus and is about 2,400 light-years from us. The “trunk” itself is over 20 light-years long. In 2003 several very young stars where discovered in the circular cavity in the tip of the trunk. The stellar wind from these hot young stars may have carved out this hole.

The image shows the Rosette Nebula. It is named Rosette because it resembles a red rose to some degree. It is a cloud of dust and hydrogen gas located in interstellar space. It glows red because highly energetic radiation from nearby giant stars stimulates the hydrogen gas to glow. New stars are being formed in this nebula.

The image was taken with a Canon XSi 450D (Honis modified) camera and a 100mm lens. The camera was mounted on an Astrotrac DSLR tracking system. 88x1 min images were combined in DSS to make a single final image. The final image was refined in Photoshop CS5 to enhance the colors, contrast, and intensities. The image was captured in Reston, VA under light polluted suburban skies in a Bortle red zone.

Heart Nebula (IC 1805), 08/27/2020

Last weekend I headed back out to the Buck Creek campground, this time by myself. The weather was clear and the moon was not yet full and I couldn’t pass up the opportunity. I was able to setup my big telescope and two separate cameras to capture images. I’ll post the other pictures soon. It was a successful trip all around.

This is the Heart Nebula and it is huge. If the Heart Nebula was as easy to see as the Moon, it would be almost ten times the size in the night sky. It is found in the constellation of Cassiopeia and is some 7500 light-years away. The lower portion of the Heart Nebula has its own designation NGC 896 and is called the Fish head Nebula. It seems to me that these two nebulae where easy to name.

SH 290 as seen from the nights of Feb 8 to 17 2013 in the back yard. This is from a stack of subs collected to test flexure. I'd selected this target because it crossed the meridian at a time when I could get the scope set up and let it run. I was more interested in seeing the trailing of the stars and if I managed to get some nebulosity, great.

I threw a stack of subs at DSS to see what would stick and it gave me 76 that qualified for a total of 25 hours 26 minutes of integration time.

As could be seen from the earlier screenshots of the PI window, there was some data visible but it was hiding deeply, just above the skyglow. The real challenge was separating the useful data from the noise.

In the end, I went away from my normal habit of using the masked stretch script and used the auto histogram tool. That helped pull the lower regions apart so that I could gently nudge the colors from the background. The atrous tool was used to aggressively control the noise -- and it worked well.

I think the annotated image really surprises by showing all the galaxies lurking in the background that I would normally cover by sending the background darker.

I think that this has taught me that there is still lots to see from the back yard. The 20 minute subs seemed to have helped. I could have gotten better contrast by going to a darker site. A more aggressive light pollution filter might have helped but it would have left more noise.

Also, there are some uncontrolled dust motes because of missing flats. Not unexpected given the way I was messing with the camera during these sessions. This was done just after I'd modified it and put the new cooler in place.

Here's the plate solve results from PI:

Eagle Nebula (M16), 07/09/2020

We had a new moon and clear skies at the same time last weekend so there was no way I was passing up that opportunity. I hooked up the RV, kissed my wife goodbye, and headed to the hills to catch some photons! Things mostly went well, mostly. As I started to setup my gear at dusk, I realized I had forgotten a critical usb cable. This meant I needed to huck all the expensive equipment into the RV and run into town. This was a two-hour round trip to Wally World and back. Then re-setup the telescope and let it run into the wee hours of the night.

This is the Eagle Nebula, an object I have shot several times before, but this time I used a fancy light pollution filter. This filter makes it possible to process the data in a simulated Hubble Telescope color palette. Short explanation is that the filter separates the hydrogen-alpha (red) and the oxygen-III (blue) light-wavelengths into separate color channels during image processing.

The Eagle Nebula is a 5.5-million-year-old cloud of molecular hydrogen gas and dust stretching approximately 70 light years by 55 light years. It lies about 6,500 light-years away. The “Eagle” itself in the center is the famous Hubble image, “The Pillars of Creation”.

The Sombrero Galaxy (M104), 04/18/2021

Like I said in my last photo, its galaxy season, lol. A few weeks ago, I took my gear up into the woods and was able to capture lots of images while in the dark skis. I have always wanted to photography this galaxy, but it is really small and far away (31 million light-year), but I did it anyways. This picture is cropped in a lot. The Sombrero Galaxy is almost perfectly edge on to our field of view, so the dust lanes really pop. It also contains one of the biggest super-massive black holes ever discovered.

Nel tentativo di riprendere l'effetto lente gravitazionale denominato SDSSJ0851+3331 (in basso a sinistra rispetto al centro dell'immagine) ho raccolto 22 ore e mezza sulla galassia NGC2683, soprannominata "Galassia UFO". E' una galassia a spirale distante circa 25 milioni di anni luce nella costellazione della Lince. La lente non si vede ancora, l'anno prossimo cercherò di dedicare ulteriore tempo di integrazione per renderla evidente.

Pose guidate da 10 minuti con newton 150/600, correttore 0,95x, camera Tecnosky Vision 571C, montatura Ioptron GEM45, elaborazione drizzle 3x con Pixinsight.

In an attempt to capture the gravitational lens effect called SDSSJ0851+3331 (bottom left of the center of the image) I collected 22 and a half hours on the galaxy NGC2683, nicknamed "UFO Galaxy". It is a spiral galaxy about 25 million light years away in the constellation of Lynx. The lens is not visible yet, next year I will try to dedicate more integration time to make it evident.

10 minute guided exposures with 150/600 newton, 0.95x corrector, Tecnosky Vision 571C camera, Ioptron GEM45 mount, 3x drizzle processing with Pixinsight.
