Another showpiece spiral, also known as NGC 3031 or Bode's Galaxy, in Ursa Major.

40 x 2-minute exposures, ISO 3200, f/4 (frames taken 25 March 2020); plus 7 x 5-minute, f/4, ISO 1600 (older frames, from November 2013). Modified EOS 600D & Revelation 12" Newtonian f/4 reflector telescope.

Frames registered and stacked in DeepSkyStacker software; curves adjusted in Canon Photo Professional; noise reduction in CyberLink PhotoDirector.

I've never been that interested in imaging this region of the Milky Way with my Samyang 135 for whatever reason, perhaps because I can't resolve the Pillars of Creation in the center of the Eagle Nebula (bright emission nebula in upper right quadrant) with my 135mm lens. Even so, the wider field is full of interesting contrasting features. This area is quite bright and colorful relative to other regions that I've imaged recently, so processing was a cinch.

Fujifilm X-T10, Samyang 135mm f/2.0 ED UMC @ f2.0, ISO 1600, 30 x 60 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker, editing with Astro Pixel Processor and GIMP, taken on Aug. 23, 2020 under Bortle 3/4 skies around the setting of the 25% illuminated moon.

Taken with a TMB92L, Hutech-modified Canon T3i DSLR, Orion SSAG autoguider and 50mm guidescope, and Celestron AVX mount. Consists of 25 360-second light frames and 21 360-second dark frames, all at ISO 800, as well as 35 flat and 50 bias frames. Captured with BackyardEOS, stacked in DeepSkyStacker, and processed in Photoshop.

Another old favourite of the Spring sky. I've had to crop this far more than I'd like, though, as the photo edges looked awful due to coma and tilt (both of which bloat and mis-shape the stars).

#مجرة_الألعاب_النارية

(بالإنجليزية: Fireworks Galaxy)‏ وتعرف ايضًا بـ NGC 6946 أو كالدويل 12، ترى بين كوكبة الدجاجة و كوكبة الملتهب، اكتشفت من قبل ويليام هيرشل في 9 سبتمبر 1798.

مجرة الألعاب النارية تبعد عنا حوالى 22.5 مليون سنة ضوئية.

المجرة إن جي سي 6946 هي واحدة من أقرب المجرات الحلزونية العملاقة خارج المجموعة المحلية، تحتوي على مستوى عال من تكون النجوم في جميع أنحاء القرص الخاص بها، بالإضافة إلى منطقة انفجار نجمي قوي.

ولهذا سميت هذه المجرة مجرة الألعاب النارية، تتسم المجرة NGC 6946 بمعدل عال في حدوث مستعرات عظمى فيها بالمقارنة لمجرتنا، مجرة درب التبانة ، حيث يحدث في مجرتنا مستعر واحد فقط تقريبا في كل مئة عام.

Maybe I'll try to add more light to this project, if the sky allow.

This is the galaxy designated NGC 7331 located in the constellation Pegasus. Inside the galaxy close to the central core is the supernova 2025rbs that I imaged on July 23, 2025. My magnitude estimate based on 90 minutes of collected data is V12.7.

Image Date: July 23, 2025. Location: The Dark Side Observatory (W59), Weatherly, PA, USA (Bortle Class 4).

Went out to look at the sky, but it was particularly windy, making for a frustrating time. This was the only decent image I was able to generate from the night, but it did come out well. Stacked with DeepSkyStacker, 50 mm, f/2.0, 3200 ISO, 101 Frames, 8m25s total exposure

Taken on the first of 3 evenings imaging the comet, though the weather was never quite ideal. On this night patchy cloud caused the uneven background in the image.

18 x 30-sec exposures at f/4.5 and ISO 3200 with an EOS 600D and Zeiss Jena 135mm f/3.5 lens on a Vixen Polarie star tracker. The frames were stacked on the comet in DeepSkyStacker, hence the trailed stars. Curves adjustment and further noise reduction were applied in post-processing.

M8 The Lagoon Nebula (catalogued as Messier 8 or M8, NGC 6523, Sharpless 25, RCW 146, and Gum 72) is a giant interstellar cloud in the constellation Sagittarius. The Lagoon Nebula 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

NGC 2903 is a barred spiral galaxy about 30 million light-years away in the constellation Leo, discovered by William Herschel. And it's a faint bugger, or at least the outer bits are - too faint for my pathetic skies really.

This is the first image I've done using dithering. Not sure how much difference it made as I wasn't able to give it enough subs anyway. Certainly increased the session time, that's for sure! I'll reserve judgement on dithering :)

Scorpius constellation as seen from Coonabarabran, NSW on 04/10/2015

Canon 5D MkII + Canon 50mm f/1.8 STM mounted on a Skytracker with an Arca-Swiss ballhead.

- 32 x 1 minute light frames @ f/3.2 ISO800

- 55 x 1 minute dark frames.

- 1 x 1 minute light frame taken with a Kenko Softon filter to bring out the bright stars.

Stacked in DeepSkyStacker with curves and level adjustments in PhotoShop. Some minor NR and colour balance in LR.

First Light results for my new "space yacht" - Meade 6000 series 80 mm APO triplet refractor :D

It's not ready to "fly high" yet, since it badly needs the field curvature corrector, but I was very eager to try the new degree of comfort and predictability of where the eyepiece would end up after next slewing :)

Hence the choice of a target...

Acquisition time: ‎‎2015.03.14, ‏‎20:37:58 GMT+4 (start of the session)

Equipment: Magic Lantern powered Canon 60Da with Astronomics CLS-CCD clip-in filter inside, attached to Meade 6000 80 mm APO via Baader Planetarium 2"-to-Canon EF adapter, riding Sky Watcher NEQ-6 Pro unguided.

FL 480 mm

Av f/6

Tv 55 sec

Exposures: 20 frames @ISO1600 and 10 frames @ISO400 plus two sets of 10 darks, 2x50 of flats and 2x50 dark flats (I'm meticulous!), no offset (shame on me!).

The sets were processed twice: firstly the all things were thrown in DSS in two groups. When only ISO 400 set was processed on its own.

And when the Photoshop "masquerade party" has begun.

The ISO 400 output was used as a base. It was stretched using gamma value of 2,5, the black level was adjusted separately for each channel and the image was saturated. When it was copied and placed over the base in Screen blending mode. The core was masked with several apllication of Gaussian blurred black blob.

When the second result (also contrast stretched and saturated) was inserted underneath. The solid black background was added also. The core on the second image was totally "black-blobbed" away. The basic layer was when also blended down in screen mode.

The result was duplicated, flattened and contrast-adjusted.

It is rather grainy - too few frames were used in too much stretched image. The abscence of offset may also affect the quality of result.

Note: would I be able to reproduce all that again, I wonder? :P

I managed to get three targets in this shot thanks to the little Asker FRA400 scope and the 533 sensor. Located in the constellation of Cassiopeia.

All data was gathered at www.astronomycentre.org.uk/

They are: NGC 7635 the Bubble Nebula. Discovered by William Herschel in 1787 it lies about 7,100 light years away and spans about 7 light years across.

NGC 7538 Northern Lagoon Nebula is the bright patch to the lower left. This is a stelar nursery some 9,000 light years away. It is actively forming proto stars, many of which are 40 times the mass of our Sun.

M52 open star cluster.

Also given the NGC 7654 tag.

Discovered by Charles Messier in September 1774. Sometimes called The Scorpion cluster lies about 5,000 light years away and is the only one of these 3 targets that can be picked up in a pair of binoculars.

My latest image of the 'Pacman Nebula' was taken this fall using my most-used astro-camera of 2024 from my light-polluted backyard.

I used a dual-narrowband filter to isolate this dynamic nebula from a washed-out city sky (Bortle 6).

While I shoot mono often, I've really been enjoying this color camera/filter combo lately.

There is still plenty of time to capture this nebula in the northern constellation Cassiopeia this month - if you need to take a break from Orion! 😆

Apr. 2017

Now that it's April, the iconic summertime objects are starting to rise high enough before dawn to photograph for northern hemisphere astrophotographers. The Trifid Nebula (M20) is one of my favorites -- a flower-like emission/reflection nebula in Sagittarius. I took the opportunity of a spectacular night up at Fremont Peak to image it through a 6-inch f/9 Ritchey-Chretien telescope -- my first night using this scope. It was mounted on an Orion Sirius EQ-G mount and guided with a StarShoot AutoGuider and Orion 50mm guidescope.

This is a composite of 25 exposures of 6 minutes each with a modified EOS 500D camera at ISO 1600. Dark and flat frames were applied. Images were stacked in DeepSkyStacker and the composite image processed in Photoshop CC.
