I applied a heavy noise reduction filter to this to try and get that smooth Hubble look :)

M65, M66 and NGC 3628; 30 million light years from home.

I was going to crop this tighter around the galaxies, but then I noticed a telltale streak on the left side of the image. After consulting Cartes du Ciel I discovered it was asteroid 128 Nemesis, which - despite its ominous name - doesn't come anywhere near the earth. (It's currently at a very safe distance of 2 Astronomical Units.)

Total exposure time: 85 mins

Telescope: Tele Vue-60 APO refractor

Mount: Vixen Super Polaris

I had to try it. Not an amazing image, but I'm happy with it considering the short focal length.

Acquisition details: Fujifilm X-T10, Samyang 135mm f/2.0 ED UMC @ f2.0, ISO 1600, 96 x 30 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker, editing with Astro Pixel Processor and GIMP, taken on Apr. 16, 2020 under Bortle 3/4 skies.

I processed with 3x drizzle in DeepSkyStacker, but I don't think it made much of a difference; I think my tracking accuracy limits the amount of detail I can achieve on tiny objects with my setup, and possible my sensor. Even though it's tiny, this is still a fairly big crop.

I plan to shoot M 101 next time - my attempt a year ago was marred by windy conditions. I probably won't bother with 3x drizzle, but might still apply 2x drizzle.

First clear night in ages, but at least we haven't had as much rain as in the north of the country.

The Ring Nebula (also cataloged as Messier 57, M57 and NGC 6720) is a planetary nebula in the northern constellation of Lyra. The tiny white dot in the center of the nebula is the star’s hot core, called a white dwarf. M57 is about 2,000 light-years away in the constellation Lyra, and is best observed during August. Discovered by the French astronomer Antoine Darquier de Pellepoix in 1779, the Ring Nebula has an apparent magnitude of 8.8. It is easy to find, as it lies about halfway between the two 3rd -magnitude stars “Sheliak” and “Sulafat” which form the bottom of Lyra’s lyre; however, it requires a moderately-sized telescope to see its beautiful ring-like details.

The open star cluster M39 in the constellation Cygnus.

Thirty 30 second images, eight dark frames, and fifteen bias frames were stacked using DeepSkyStacker, then enhanced with Adobe Lightroom and Photoshop Elements.

Comet Lovejoy looking spectacular for Xmas now with a nice bright tail.

I was surprised to see the small horizontal fuzzy blur under the comet a distant Dwarf Galaxy NGC2188 32.5 Million Light Years away and very dim at Magnitude 12. Making it the dimmest most distant object I have ever photographed!

This is just a small part of the nebula. I would have to do a pretty large mosaic to incorporate it all.

NGC7000 is an emission nebula in the Northern constellation Cygnus. At 1,700 light years away and about 100 light years across, it's a fair sized nebula.

Photographing the Milky Way is my Muse. I keep going back to it seeing if I can approach it from another perspective. It's intensely beautiful. If you've never seen it, then you owe yourself an opportunity to go away from the city or town and out to a rural area. Even a 20 minute drive outside of the city limits will take you to a dark enough sky to see the general shape of the bright Cygnus region. This was taken the morning of August 12 during the recent Perseid meteor shower.

A view of the Andromeda Galaxy in the constellation of the same name captured in a stack of ninety-one images that were exposed for 10 seconds each using a hand-driven, barn-door type tracking mount (two boards, a hinge, and a screw you turn by hand). This photo also shows Andromeda's two satellite galaxies, M32 and M110 (see image notes for the locations, M110 is the small elliptical galaxy slightly below center).

I caught a news story a few days ago about a supernova in galaxy NGC 3184 and decided to try and image it on March 29, 2016. Problem was the high winds here in Pennsylvania. The magnitude was listed in the 15 range, but decided to try imaging it using my Canon EF 400mm f/5.6L USM lens.

The wide field image (see my other Flickr post or my blog) is a clip from a full frame, stacked 14-minute total exposure using a Canon 6D and Canon EF 400mm f/5.6L USM lens mounted on an iOptron ZEQ25 mount. 14 x 60 seconds at ISO 3200, stacked in DeepSkyStacker and further processed in Adobe Lightroom and ImagesPlus.

I then clipped the galaxy from the full frame view and processed it in Lightroom. I found a great pre-supernova (baseline) image by Adam Block (who gave me permission to use his image for comparison purposes – thank you Adam). Adam’s image can be found at www.caelumobservatory.com/obs/n3184.html

I hope to do additional imaging as time permits.

My Nikon D5000 have a serious issue with its sensor. On the right corner and top of the image we can see it failure. A region of the sensor which does have a lack of sensitivity.

First I though it was a "flat frame issue", but it's not. Darks and bias doesn't help.

Only after a carefully processing I'm "ok" in posting this picture. But my Nikon D5000 is old, and I'm not happy to say that it needs to retire.

I uploaded a version of this a month or so back that was supposed to be a combination of this year's data and last year's. Turned out it wasn't - what I got out of DSS was exactly last years data - it completely ignored this year's. DSS playing silly buggers.

This, on the other hand, is the combined data - 2 hours 23 minutes of 60 second subs. This is about three quarter frame, and rotated to provide a different angle - change is as good as a rest. Nice and small and cute :)

My mount has been serviced and now appears to be doing its thing as it should. I'll now wait for the next disaster to befall me, as is the nature of this stuff :)

I remember now, why I did capture the Crux again. My hope was to compare, side by side, my old Nikon D5000 and the "new" Canon T6i. Well, my D5000 served me well for a long time, but now it needs to retire. :)

I found an empty piece of plastic the other day, on which I had no hesitation in slapping a modded Canon 500D, purchased at a very reasonable price from James Stannard here. There then followed a bit of a learning curve - having been used to a Nikon - which has taken up the best part of two weeks. But I got there in the end :)

This is another collaboration with my good friend Dave Williams from the northern wastelands, who generously donated large portions of Ha, used as luminance.

I will now spend some time trying to breathe life into my Nikon D70 so that I can inflict some considerable pain on the thing, before I eventually kill it - slowly.... :)

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.

NOTE: This is a pseudo-narrowband image. I tried with post-processing to give the impression of using Ha, OIII and SII filters. The original version shows only red nebulosity (hudrogen). It was really a persistent and painful struggle in Photoshop :)

Secondo lavoro di astrofotografia, ritratta la Nebulosa di Orione (M42)

Cielo con molto inquinamento luminoso e nebulosa lontana dallo zenit:

quindi si potrebbe fare molto meglio.

Critiche, commenti e consigli graditissimi.
