Constellation Cygnus, the Swan, is in the trend now, so I want to participate. The black gap in Milky Way (sometimes reffered as the Nothern Coal Sack :) where the Swan resides, is full of emission nebulae, so it is there I pointed the camera this time.

SWANS stands for Semi-Wide Angle Nebulae Survey. I'm a big fan of the way how NASA and CERN name their experiments and missions.

Lots of upgrades in all aspects of imaging. Prime lens, UHC filter, firmware hack in camera, three overlapping datasets collected in two nights, artificial flat-field image, automatic stitching, formalized processing in Photoshop. This is the positive side. On the other hand, the second night of imaging brought with it the hazard of dewing. That was the negative experience. Cost me a lot of precious time.

Some trailing is apparent at 1:1 view and bugs me, but with the arrival of polar finder it wouldn't be an issue anymore, I hope.

Another issue is the inconsistency of data, since the "Albireo" panel is this image and it differs from two other in ISO value (3200 vs 2000) and in amount of data (10 subframes vs 29 and 20, respectively).

And yet another bit of information: the Crescent nebula (see note on the image) is an unusual object. It's an emission nebula produced from the outer layers of so called Wolf-Rayet star. These rare objects are massive - about 10-15 Solar masses - highly evolved stars that had lost the outer hydgrogen shells and are in fact the exposed helium cores that produce tremendous amount of energy and dense streams of "stellar wind". Amazing objects :)

The Sun's deepest dive was -17° @01:30, so stricktly speaking I was imaging in the dusk.

Equipment:

Canon EF-S 60mm f/2.8 macro USM lens and Baader Planetarium 2" UHC filter mounted in front of the lens via step-down ring attached to Canon EOS 60D running Magic Lantern 2.3 firmware override riding on Vixen Polarie tracking platform over photo-tripod (alltogether codenamed "Anywhere Is, SWANS configuration").

Aperture 21,4 mm

Focal length 60 mm

Tv = 60 seconds (Magic Lantern's bulb timer and intervalometer rock the suburban skies :)

Av = f/2.8

ISO 2000 for "Deneb" and "Sadr" areas and 3200 for "Albireo" area

Exposures: 29 for "Deneb" area, 20 for "Sadr" area, 10 for "Albireo" area (plus 10 dark frames and 10 offset frames plus 2 fake flat-field frames).

Processing: Contrast was set to "linear" for all images in Canon DPP and 16-bit outputs were fed to DSS.

Flat-field images were made by applying Gaussian Blur of 250 pixel radius to a randomly chosen image from the series. After blurring the histograms were adjusted to end at 70% of saturation. Since I have aquired three series of overlapping fields, I made a Master Flat by combining fakes from both series. Works fine - without it the Veil nebula can't be seen due to vingetting.

16-bit stacking results were then processed in Photoshop with AutoContrast and Levels (namely gamma was set to 3,5), stiched in Microsoft ICE (that's coool!) and back in PS Curves were applied(skewed sigmoid curve was applied at first step, and at step two the segment of red and blue curves corresponding to the brightness of nebulae was elevated).

* 1 Megapixel = 1048576 pixels.

This is my first image of 2021 and my first time using a hydrogen-alpha filter. It’s amazing how far away and faint this object is, but with the right equipment, hidden wonders beyond everyday light pollution can be uncovered.

I decided to go with a fiery look considering this was my first attempt with a Ha filter. The bright reds and burning oranges never get old especially when you understand this area in space is both a hot star-forming region and where tons of cold, dark gas come together to create beautiful, artistic silhouettes.

A guided image of the open star clusters M35 and NGC 2158 in Gemini taken last night using a ZWOASI183MC Pro astronomy camera on an Astro-Tech 70ED refracting telescope with a .8 focal reducer. Thirty 30 second images were processed using DeepSkyStacker, Adobe Lightroom, and Topaz AI. NGC 2158 is the smaller cluster on the top of the image and is at a distance of 14,700 light years from Earth. The larger cluster in the middle of the image is M35 and it is at a distance of 2800 light years from Earth. M35 is estimated to about 100 million years old where as NGC 2158 is thought to be about two billion years old. The bright star at the bottom on the image is 5 Geminorum. It is an orange giant at a distance of 568 light years from Earth and is 20.5 times the Sun's diameter in size.

NGC 7027, also known as the Jewel Bug Nebula or the Magic Carpet Nebula, is a very young and dense planetary nebula located around 3,000 light-years (920 parsecs) from Earth in the constellation Cygnus. Discovered in 1878 by Édouard Stephan using the 800 mm (31 in) reflector at Marseille Observatory, it is one of the smallest planetary nebulae and by far the most extensively studied.

Here's a quick shot of Comet P46 Wirtanen above a palm in my suburban backyard, taken through a small gap in the clouds last night. Lots of Brisbane light pollution so the comet was not visible with the naked eye, but it was easily spotted in 7x50 binoculars, and the camera picked up its greenish glow fairly well.

This is 10 x 3.2 second exposures with my 100mm macro lens at f/2.8 and 3200 iso, stacked in DeepSkyStacker.

I saw a few meteors as I was imaging this one, and was excited to find that I'd caught a small Perseid shooting through the Heart Nebula on one of my frames.

“Wow, you must have a good telescope to take photos like that”. These words get said to me quite often, and I can understand why. The first few times I saw a photo like this one, with its thousands of stars; the colourful nebulae around the stars in the Rho Ophiuchi region (left-hand side, mid-way up the photo); the filigrees of interstellar dust and gas seemingly streaming across the field of view; and the lovely white dot that is the planet Saturn (to the right and just below centre), I had a similar reaction. I pictured an amateur or professional astronomer huddled over some equipment consisting of a telescope that was following the movement of the night sky, with a camera (costing an amount that had five digits in it) attached, whiling away the hours on a cold night somewhere away from city lights.

This image was captured away from the lights of major cities, but it wasn’t too far from the country city of Lismore, in New South Wales, Australia. Yes, a camera was used, but it wasn’t attached to a telescope and it wasn’t tracking the sky’s movement while taking the photos. Creating this image involved taking eleven images using my Canon DSLR camera, set at a very high sensitivity (ISO), a 50mm standard lens (that only cost around the $150 mark), a tripod, and a remote shutter release to stop the camera from shaking and ruining the shots. The eleven photos were taken close to each other and each one was exposed for only five seconds. I also shot some extra frames with the camera’s lens cap on, which are used to work out how much digital noise the camera creates. These are all combined in a process known as “stacking”, using free software to do the job. Adobe Lightroom was then used to crop the image, adjust the exposure and tweak the contrast and colour saturation.

Part of the famous Veil Nebula supernova remnant. The bright star with the reflection halo is 52 Cygni.

Unfortunately, this has the frequent problem I get with bloated stars towards the lower right. Not got to the bottom of it yet, but something in the optical chain must be getting out of alignment. I do check collimation before each session. Anyway, I was pleased with the detail in the nebula, so have posted despite the flaws.

After weeks of cloudy skies, I finally had the opportunity at grabbing a couple of shots of Lovejoy on it's passage past us towards the Sun.

Used 7 x exposures at 100mm, via Deepskystacker, which has removed the green tint from the Comet that shows up single exposures - obviously I need to do some reading up on the Software :)

This is the first image out of my first foray into DSO astrophotography. What have I gotten myself into! This is a stack of maybe 39 100-sec. exposures taken from my driveway in the middle of town. I took these the second night out because the first night out, I had accidentally set my tracker to track at moon speed, not star speed, which was enough to create significant trailing. 😣

That first night, I had over twice as many exposures. Lesson learned...along with a few others (check and recheck focus often, don't set up everything and then realize you can't polar align because you forgot to check that Polaris wasn't blocked by your house, allow camera to cool down to outside temp well before shooting, if there's much wind just don't bother, check the dew point...on and on). Man, there's so much that goes into AP, and I don't even know what I don't know yet!

Anyway, I'm pleased for the first time out! Stacked in DeepSkyStacker, edited in PS. Fuji X-E2, f/6.2, ISO 800, ~150mm.

By no means the best picture of the Orion Nebula but for my very first try using only a tripod, Sigma 150-600mm and a Nikon D7200 I'm pretty happy with the result!

As the EXIF data isn't showing I'll run through my set up:

F 6.3

600mm

ISO 6400

1.6 Second exposure

10 exposures stacked using DeepSkyStacker

Slight post processing and cropping in LR/PS

Any help with capturing more detail would be greatly appreciated!

Thanks for looking and have a great day!

Jellyfish Nebula "true color" narrowband. Stacked, assembled, and processed with the following exposure times: 20X900"Ha, and 20X900"OIII.
