Canon 20D, Tamron 18-250mm @18mm, f/3.5, H1 (3200) ISO, 15 Second Exposure
Stacked 40 light frames with Master Dark and Flat Frames, (each made from 20 shots) and made curves and saturation adjustments in Deep Sky Stacker.
Post Processed in Photoshop CC with Astronomy Tools Actions, using a number of light pollution and noise filters.
Image taken in New South Wales, Australia.
Known as the Cocoon galaxy.
The smaller companion galaxy is NGC 4485. Referred to collectively as ARP 269.
The galaxies passed close to or through one another sometime in the past and, it's almost certain gravity will bring them back together several billion years in the future.
The red/pink areas are prime star forming regions where dense clouds of ionised hydrogen are irradiated by ultraviolet light from the hot, young stars within.
ARP 269 can be found in Canes Venatici some 24 million light years away. The two galaxies having now passed by one another are now approximately 24,000 light years apart.

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
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
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! :)

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.

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.

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.

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. Mi piace ed affascina il dettaglio sulle galassie ed il bilanciamento colori ma è uno scatto tutto da rifare con un cielo degno, sob!

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
This is one of the most beautiful and distinctive nebulae in our galactic neighbourhood.
The eye-catching Bubble Nebula is designated as NGC 7635, Sharpless 162 and Caldwell 11 and lies close to the direction of the open cluster Messier 52.
It is 7 light-years across – about 1.5 times the distance from our Sun to its nearest star, Alpha Centauri and resides 7100 light years from Earth in north-western Cassiopeia close to the border with Cepheus.
The 8.7 magnitude seething star forming this nebula (BD+60°2522) is 45 times more massive than our Sun. Gas on the star gets so hot that it escapes away into space as a stellar wind moving at almost 7 million km/h.
As the surface of the bubble's shell expands outward, it collides with dense regions of cold gas on one side of the bubble. This asymmetry makes the star appear dramatically off-center from the bubble, with its location in the 10 o'clock position in this image.

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.

I'd been eyeing this area in Camelopardalis for awhile because of the concentration of dark nebulae. Barnards 8-13 are the dark nebulae on the lower left.
It was a bit of a let down to process - It's not nearly as neat as the the dark nebulae in Taurus or Cepheus, in my opinion, but it was fun to explore anyway. I almost didn't post it because it's a bit underwhelming, but since there aren't too many images of this area, I decided to post anyway.
Fujifilm X-T10, Samyang 135mm f/2.0 ED UMC @ f2.0, ISO 1600, 50 x 60 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker, editing with Astro Pixel Processor and GIMP, taken on Nov. 24, 2019 under Bortle 3/4 skies.
Guess who got an ED80 for his birthday then? :)
This is my first half successful attempt at using the thing with my new go-faster budget guiding kit :) Guiding was fine, but I ran out of vis towards the end, and as the Reading Fest had just kicked off, I had to contend with searchlights passing through the frame every 20 seconds or so! So on that basis, this ain't too bad - even though it needed a little encouragement during the processing :) Horrendously noisy, hence the small image :)
