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.

Manually, off-axis guided for 11 x 4-minute exposures at ISO 1600, f/4. Modified EOS 600D & Revelation 12" Newtonian reflector telescope.

Registered and stacked using DeepSkyStacker; initial curves adjusted in Canon Photo Professional; final curves & colour-balance adjusted using Paint Shop Pro; noise reduction via CyberLink PhotoDirector.

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 :)

 

6sec exposures, ISO5000 at f/2.8 - cropped down to 50%

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.

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.

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:

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

 

Equipment used:

Canon 200mm f2.8 lens at f4, Atik 428ex camera, AP900 mount, DeepSkyStacker, Photoshop levels, curves, blending, guided with ZWO174mm and Stellarvue SVR90T.

Globular star cluster M3

 

An incredibly compact ball of stars, containing some 500,000 burning balls of gas. 33,900 light years away from us and closing fast, at about 5,500 MPH.

 

150 exposures of 40 seconds each. All combined together with 200 calibration shots in a free program called DeepSkyStacker and post processed in StarTools.

 

Images were taken with a Skywatcher 8" reflector telescope and my Canon 1100d attached at prime focus.

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 :)

My first foray into using a dedicated astro camera.

 

Images were taken on the first opportunity of a cloud free night (or close to it) but there was however, a full moon.

I suspect the full moon took away some of the finer details and the blues/purples. Time will tell.

 

These image files (FITS) were stacked with DeepSkyStacker and then edited in Adobe Photoshop.

After I have spent hours to watch the starry sky, I tried to realize a image of our nearest neighbor galaxy : Andromeda M31.

  

Wihtout using a tracking mount, I took 64 images (+ 20 darks) that I superimposed with DeepSkyStacker software.

  

In order to improve the clarity of the photograph, I used lightroom. But the focus is not perfect unfortunately...

This is a pigging thing! Either my skies ain't up to it or the ED80 is too slow, but this is 11 hours of hard work (well, sort of) and required no small amount of encouragement during processing. And the noise you wouldn't believe!

 

Unlikely to get the opportunity to add to it this year, so maybe next :)

 

No apology for the spikes - they hide a multitude of sins, and it is a christmas tree after all :)

Not sure that I've gained much, although a little less noisy in the wispy bits, and a couple of fuzzies visible. Don't think I'll get much more out of this target without a serious upgrade of kit! :)

Not my best attempt as I went a little too long with the exposures I think, but still not my worst .

 

NGC 2392 can be found in the constellation of Gemini about 5,000 light years away.

First spotted by William Herschel in 1787. It's thought that this planetary nebula started to form around 10,000 years ago.

Planetary nebulae are formed from dying stars that have burnt through all their fuel supplies and start shedding off outer layers in to space.

The Orion Nebula, also known as Messier 42, M42, or NGC 1976, is a diffuse nebula situated south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 ± 20 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2000 times the mass of the Sun.

La nebulosa de Orión, también conocida como Messier 42, M42, o NGC 1976, es una nebulosa difusa situada al sur del Cinturón de Orión. Es una de las nebulosas más brillantes que existen, y puede ser observada a simple vista sobre el cielo nocturno. Está situada a 1.270±76 años luz de la Tierra, y posee un diámetro aproximado de 24 años luz.

This is a difficult one for me as the un-focal-reduced ED80 is a little slow, but the Ha helps. Added 35% Ha to the red channel to give it a boost, as well as using it for luminance.

Thank all for your visit and awards.

A couple of galaxy images from the rare clear night on Saturday.

29 x 1-minute exposures, ISO 6400, f/4. I also included a handful of 10-minute exposures at ISO 1600, taken previously, to further reduce digital noise. Modified EOS 600D & Revelation 12" Newtonian reflector telescope.

Frames registered and stacked in DeepSkyStacker software; curves adjusted in Canon Photo Professional; noise reduction in CyberLink PhotoDirector.

150mm (750mm FL) F5 Newtonian with GSO coma corrector.

 

First try with autoguiding using PHD2. Unfortunately the 3D printed guidescope mount was not nearly robust enough. 2/3 of the exposures were thrown out.

 

Stacked with DeepSkyStacker and post processed in Photoshop.

 

Unfortunately a large number of Geo satellites were present in the view and created streaks.

 

Next -- attempt to remove that pesky light gradient from the background

North-American and Pelican nebula imaged on the night of September 2, during a few hours of nautical/astronomic twilight in Tromsø. I opted for "mono" 12nm-filter as there was still a lot blue in the Arctic autumn twilight night sky. Seeing conditions were unusually stable compared to the usual turbulent atmosphere on the coast of northern Norway. Auroral activity was also quite low.
