Another clear sky, albeit with half a moon :)
Continuing my obsession with all things cluster, this is M67 in Cancer. Apparently there are few Galactic clusters known to be older (this is something like 4 billion years old), and none of them are as close as M67, so it is the subject of much study (according to Wiki). Slight variation in the spikes on this one, just to ring the changes :) A little noisy, but I had some trouble retaining the colour so decided to put up with it.

Messier 31, the Andromeda Galaxy, looks much better photographed from the dark sky of Killarney Provincial Park than downtown Burlington!
Taken with a Canon 70D fitted with a Sigma 50mm Art Lens mounted on an iOptron SkyTracker. Stacked in DeepSkyStacker, ten 60 second light frames shot at f/1.6, ISO 1600, with in-camera noise reduction on, and ten bias frames, no flats.
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.

Yep, my first comet :) 5,5m - not bad to try for the first time. If not the Moon :(
Left image is what I consider "normal", the right image is overcooked to drag out, kicking and screaming, what I think is the comet's tail.
Acquisition time: 07.01.2014 22:22-22:58 MSK (UT+3), comet's maximum elevation for me was around 22:41 MSK and peaked at 31° 37'.
Equipment: Canon 60Da with Astronomics CLS-CCD clip-in filter and Baader Planetarium MPCC MkIII coma corrector on Celestron OMNI XLT 150 mm Newtonian reflector riding on Skywatcher NEQ-6 Pro.
Exposures: 33 @ISO800 55 seconds with 48 darks, 60 offset frames and 50 flat field frames.
Capture software: Magic Lantern
Processing: images were stacked in DSS in comet tracking mode and stacking result was post-processed in Photoshop.
Note: the Moon: -11,8m, 93,4% full, 19° 07' high.
Note 2: DeepSkyStacker is clever. Of 33 frames I have used it had mistaken the star for the comet on just one frame. Predictive powers :)

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 :)
Aquisition time: 03 and 04.08.2013 between 00:00 and 01:40 MSK (UTC+4)
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).

Taking advantage of a clear night for some astrophotography loving. Oh, and read the lovely interview I did for Meera Sethi at Inkling Magazine: www.inklingmagazine.com/articles/qa-phillip-chee
Fujifilm X-T10, Samyang 135mm f/2.0 @ f2.0, ISO 1600, 47 x 60 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker, editing in GIMP, taken Sept. 3 under Bortle 3/4 skies.
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. The placement of the meteor is uncannily similar that of this APOD by Roger Clark, which is one of those inspirational astroimages that has stuck with me: apod.nasa.gov/apod/ap160905.html
Used my 10" f/4 Newtonian and Atik 314L with narrowband filters to capture 6 subs at 5mins each in OIII and 8 subs at 5mins each in Ha. Stacked both image sets in Deepskystacker and colour combined (Ha,Ha,OIII) in Maxim D/L 4. Final processing carried out in Photoshop. Image taken 9/10/15
This is two interacting galaxies, NGC 4490 being the larger, and NGC 4485 being the smaller one above.
They have already passed by one another, but interacted heavily with each other as they went. They are still connected by a stream of material stretching some 25 light years.
The pinkish spots on NGC 4490 are area's of intense star birth which have been triggered by the close fly by from NGC 4485.
They have passed through each other now, however gravity may well just pull them back together and smash them in to each other again and again over billions of years.
We are safe here for now. This is all happening about 24 million light years away in the constellation of Canes Venetici.

Fujifilm X-T10, Samyang 135mm f/2.0 @ f2.0, ISO 1600, 60 x 60 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker, editing in GIMP, taken July 30 under Bortle 3/4 skies.
Reprocessed Aug. 2 without using a luminance layer, to keep emission nebulae red; I like the colors much better now and the Seahorse Nebula also pops better in this version. I decided several months ago to use luminance layers in processing after getting some nice results, but after reprocessing several images without luminance and getting better color results, I'm thinking using a luminance layer is now the exception rather than the rule for me.
The universe is in constant motion in many ways, ranging from slow movement following nice, predictable, easy-to-understand Newtonian physics to mind-blowing accelerating cosmic expansion. Please refer to Monty Python's Universe Song for more information! The black smudge along the bottom is a line of trees at the edge of the field I was shooting from, blurred by the motion of the sky tracker which rotates the camera at the same rate as the Earth, pointing continuously in a fixed direction in the sky. Really, it's nowhere near as complicated as it sounds! :)
Taken under the glorious dark sky of Killarney Provincial Park in Ontario, located about 30,000 light years from the centre of the Milky Way galaxy!

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.

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.
Manually guided for 5 x 7-minute exposures at ISO 1600, f/6.25. Modified EOS 600D & Sky-Watcher ED80 refractor, piggybacked on a Celestron C8 telescope for guiding.
The red halo around Gamma Cass is an imaging artefact (Probably an internal reflection). Also, I had to crop the image due to badly distorted stars around some edges - evidently something wasn't aligned correctly.

ennesima elaborazione da frustrato :) alla disperata ricerca della flux (la cui visibilità varia a seconda del tasso alcolico del medesimo), il tempo non collabora purtroppo.
