This is the open cluster designated NGC 7419 in the constellation Cepheus. This cluster is between 7,500 and 11,000 light years away. Its location is behind some dark nebulae which reddens the color of the stars. The cluster does contain no less than five red supergiant stars - this is one of my favorite open clusters!

A spiral galaxy in the constellation Camelopardalis.

It goes by the nickname of the Hidden galaxy as it's a very difficult target for visual and for photography. This is due to it lying pretty much in the same line of sight as the Milky Way and all it's bright stars and dust lanes. Except IC342 which is about 11 million light years further on.

Thought I'd take the opportunity to capture the comet, currently in Andromeda, again. The sky was less murky than last night, but it's likely to be the last clear night for a while.

22 x 30-sec exposures at f/4 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, with curves adjustment and further noise reduction in post-processing. Also Starnet++ software used to temporarily separate the stars and comet and prevent the stars bloating when comet contrast is stretched; this has revealed more of the tail that would otherwise be lost in the star background.

The Pinwheel Galaxy (also known as Messier 101, M101 or NGC 5457) is a face-on spiral galaxy 21 million light-years from Earth in the constellation Ursa Major. The giant spiral disk of stars, dust and gas is 170,000 light-years across — nearly twice the diameter of our galaxy, the Milky Way. M101 is estimated to contain at least one trillion stars. The galaxy’s spiral arms are sprinkled with large regions of star-forming nebulas. These nebulas are areas of intense star formation within giant molecular hydrogen clouds. Brilliant, young clusters of hot, blue, newborn stars trace out the spiral arms. (ref: Wikipedia and NASA)

Pleiades M45 last night. Moon was out, so hard to get detail! 🔭

Stacked 20 lights, iso 800, 180seconds and processed in DeepSkyStacker and Photoshop. Nikon z 50 and Skywatcher Esprit 100.

I tried the globular cluster M13 in the constellation Hercules again this year. This time I used the 1000 mm f/10 Maksutov-Cassegrain telephotolens MC MTO-11CA (nicknamed "Russentonne" or "russian barrel" due to its stocky look and its provenience), together with the Samsung NX30 and mounted onto the Star Adventurer tracking mount. It's actually quite daring to do this, particularly without guiding, since the mount is not really designed for such a long focal length. Nevertheless, I managed to get around 100 reasonably clear 30s subs (although with a woeful success rate of only about 1 out of 3, i.e., 300 acquired, 100 accepted).

Still, I think it was worth the effort. Sharpness is homogeneous and decent after some careful post-processing, and star colours come out nicely after photometric calibration, and -typical for this lens- without any chromatic aberration. The depth of the photo is not awesome with just short of one hour useful integration time, but the galaxy NGC6207 already starts to appear at the top left.

About 9.5 hours of exposure over four days using a Tamron 150-600mm lens set to 300mm attached to a Canon EOS 50D(modified). Taken in strong Los Angeles light pollution under the hated light pole. I really need to invest in a light pollution filter but they're expensive...

Night shift today with my son Kevin. The green dot on the top right is the comet "Leonard". It passes the earth only every 80,000 years (!) and is visible this year from late November to early December. Unfortunately the weather is very cloudy, we have been watching the weather forecast for days and saw last night that this morning could be an opportunity with a lot of luck. So we got up at half past four and searched. After about 30 minutes we had found it. Then made a total of 120 pictures each 4 seconds and stacked them with DeepSkyStacker. Lens was the "bokeh master" Sigma 105/1.4.

While I'm waiting for a new 12mm f2.0 lens, I thought I'd test my new Fuji X-M1 with the kit zoom under the light polluted skies of suburban Melbourne at ISO 6400. Then I pushed and played as much as I dared.

It's not realistic, but it is remarkable what a digital camera and software can do these days.

A photo of our galaxy, the Milky Way, taken just outside our chalet at Crystal Springs Mountain Lodge in Mpumalanga, South Africa. It's amazing what a dark, clear sky can show (along with a little work on the computer). This is 10 photos that I took (each 30 seconds exposure time), stacked together (using Deep Sky Stacker), and then edited a bit in GIMP. My first real Milky Way shot!

If anyone is curious about how I went about getting this shot, I wrote a "how-to" here: digital-photography-school.com/forum/how-i-took/197256-mi...

there the stars are born from the Cocoons.

Covering the large portion of the Milky Way, which is the disk subsystem of our Galaxy, constellation Cygnus houses a lot of gaseous and dusty entities, both bright and dark. This image features among others the tiny bright Cocoon nebula (IC 5146/ Caldwell 19) which is a star formation region and much more prominent dark filament of Barnard 128 (the Snake nebula).

M103 aka NGC 581 is one of the most distant open clusters known, with distances of 8,000 to 9,500 light years from Earth and ranging about 15 light years apart. The cluster is about 25 million years old. Thus spake Wiki.

To me, it's number 27 :)

Taken with a TMB92L, Canon T3i DSLR, and Celestron CG-4 mount. Consists of 34 light and 20 dark frames, each a 45-second exposure at ISO 800, stacked in DeepSkyStacker and processed in Photoshop.

First light with my first ever dedicated astronomy camera. It was a trial and error evening. After a lot of hair pulling and youtube watching, I managed to get most of the equipment talking to each other. So I decided to try it out on an easy target, Messier 82 the Cigar galaxy. I won't bore you with M82 facts . . . this time. If you do want to know, I did post a picture of M82 not long ago taken with my DSLR. If you flick back through some of my recent pictures you'll find some M82 facts there.

And now for the really boring bit, equipment used:

Skywatcher Quattro 8" Newtonian Reflector steel tube with the f4 aplanatic coma corrector, Skywatcher EQ6 R pro mount, Altair Starwave 50mm guide scope, ZWO asi120mm guide camera mini, ZWO asi533mc pro cooled to -10c, ZWO asiair plus.

20, 3 minute exposures bin 1 gain 0, stacked with darks, flats and bias.

DeepSkyStacker, StarTools and Affinity Photo used for processing.

I think I stopped the aperture down a bit too much on this one, causing the diffraction spikes around the Pleiades's brightest stars. Next time, I'll try f/5.6 or f/6.3.

Clear sky, no moon, new camera, and news of a comet in Taurus -- who cares if it's a little cold out there....

Posted to Slider's Sunday, even though the post-processing is relatively mild by that group's standards. In particular, let me emphasize that Lovejoy and the Pleiades really did share this little section of the sky. But posted to SS because it used a new (to me) color processing strategy.

Averaged the multiple (28) images in DeepSkyStacker, and imported the result into the Gimp, along with -- and this was the innovation -- an extra copy of the last exposure as a new layer. I roughly white-balanced out the skyglow in the new layer, smoothed it, bumped up the contrast (which has the effect of increasing saturation), and made this the "color" layer to emphasize the actual green and blue colors of the comet and stars.

Comet ATLAS C/2019 Y4, discovered in December 2019, has been quickly increasing in brightness over the last few months, and many of us hope that trend will continue; past projections put it as reaching naked-eye brightness this April or May. However, it's brightness has recently plateaued around magnitude +8. That and an elongated nucleus suggest that it might be disintegrating.

It was likely about magnitude +8 when I photographed it last night, April 9th, near Star 42 Camelopardalis. I'm not sure what the faint nebulosity is to the lower left of the comet: either Dark Nebula HSVMT 25, integrated flux nebula (IFN), or it's simply an artifact. Galaxy NGC 2366 is also apparent in the upper right corner.

Acquisition details: Fujifilm X-T10, Samyang 135mm f/2.0 ED UMC @ f2.0, ISO 1600, 50 x 30 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker (used comet stacking mode so stars and comet were stacked separately and then combined), editing with Astro Pixel Processor and GIMP, taken in the 30 minute-window between astronomic dusk and the rise of the 93% illuminated moon on April 9, 2020 under Bortle 3/4 skies.
