The Horsehead , The Flame and Alnitak - HaO3RGB JanFeb2020
MarsG76 posted a gallery image in Member's Album
From the album: Deep Sky Imaging
I managed to get some time to process another of my images exposed in January/February 2020. This was the last image when my USB port on my Astro40D failed. This happened while imaging this scene but it happened toward the end of the imaging plan so I got almost the subs that I wanted. The total exposure time was 16 hours and 16 minutes in ISO1600 for all of the subs, RGB, (OSC through the UV/IR Cut filter), HAlpha and OIII. Imaged through my 8" SCT at f6.3, 1280mm FL.© Mariusz Goralski

Horsehead and Flame nebulae around the star "Alnitak" in "Orion's Belt" in the constellation of Orion. The nebulae are located approximately 1350LY for Flame nebula and 1500LY for the Horsehead curtain glow nebula. Alnitak is a bit closer at about 1250LY and is the source of light for the glow of the nebulae. The Horsehead nebula is a cold dark nebula silhouetted against the pink hydrogen alpha emission nebula IC434. The Horsehead shape is just the shape of the nebula that blocks that part hydrogen emission of IC434. This image was taken using a full spectrum modded Canon 40D. Image con© Mariusz Goralski

From the album: Alt-Az / NoEQ DSO challenge
Try 2 at all nebulas around alnitak, from heavy light-polluted skies oh home around Paris but with UHC filter. Much better than try 1, thanks to number of subs, but still difficult to come, I suppose because of limited sensor depth. (or is it LP?). However some color is missing, had to use manual BV calibration in Regim to get something barely acceptable. Capture: 101 good of 123 lights x 25s x 2500iso, 30 NG darks, Olympus E-PM1 with Skywatcher 130PDS on Celestron Nexstar SLT, Skywatcher ComaCorr and TS-UHC filter.

The Horsehead Nebula in Orion. I have always wnted to image this but unfortunately I ran out of time to collect any colour data and I did not get much luminosity as it went behind some trees. So I have tried to get the best I can out of 5, 3 minute frames. A target for another day I think. -
Reading a few articles about the HorseHead Nebula and wondered if I could bag it visually. It's a clear night on January 1st and a back garden session chasing my quarry with my 200P Dob. It's bloomin' cold (-4°C) outside and I'm wrapped up like a Michelin Man. The seeing is fair to good. Those who have read any of my other reports will know I'm very fortunate to enjoy Bortle 3/4 skies to the South and my "test objects" M1, M33 are easy catches with a 27mm BST Starguider. M33 was also visible through 8x40 field binoculars before dinner, suggesting a good evening was at hand.

Just had a lovely session on the winter targets that are now coming into view in the early hours. These were the targets that I first tried out my NV monoculars when I got them in November last year so it’s nice to give them another go with the greater experience and better equipment I have now. This was also the first proper go with my Harder Digital Night Vision momoculars and chroma 5nm Ha filter combination. The views were fantastic - I compared side by side with my photonis 4g Night Vision and 6nm Astronomik filter and the gap between the two setups is large. The angelfish was c

Hi, During the 3 clear nights in a row, I had last week, I could not resist giving the Horsehead Nebula a go, using my Vixen VC200L. Whilst imaging with my Canon 450D via APT, I could not make out the Horse's head whatsoever on my laptop screen, but I knew I was on target, because I could see NGC2023, at the bottom of my screen. Anyway I was pleasantly suprised with this result after processing through APP and tweaking in GIMP. Not the total failure I was expecting. Image Info:- Vixen VC200L Telescope Canon 450D camera unmodified ISO 1600 All I could do before fog ended t

I've been sitting on this data for quite a while (it's from Jan 2017). I've had a few goes at trying to process it, but always junked the results - mostly because of Alnitak! I've bitten the bullet and just posting it here to try and draw a line under this lot (and I've not done much else recently - illness and summer light nights...). Flare and scattered light in the field hasn't helped me and there's a bit of fringing with the brightness of the star. I have since cleaned the objective on the FLT110 as it was filthy, and I may have struggled with transparency, but I'm not sure what else

Cracking night, last night (15-Dec-2017) although with temperatures a bit below freezing and gusty winds. Having discovered that the spacing for my QHY8L on the Hyperstar was incorrect by 3mm despite using the Starizona-supplied spacer, I'm now using the excellent Baader Universal Filter Cell to give me nearer to the correct spacing. Still not quite there yet, though. To check it all out I went for a number of targets for a relatively short time. Here's my go at the Horsehead. Hyperstar 9.25" with Baader UFC and IDAS P2 filter Avalon M-Uno guided and dithered with Nebulosi

Hi again! Last time I imaged IC5070 for approx 3 hours, then as Orion rose up I decide to use up the last of the clear skies imaging B33/NGC2024. 15 x 600s at ISO1600 with Canon 1000d, ED80 FFx0.85, darks and bias. Looking any advise on detail etc, how does guiding look, focus, etc. I'd like to try to progress so feedback welcome. It is still noisy, so definitely need more subs. I've also lost the plot somewhere with it somewhere during processing as there is artefacts all over the show! Thanks in advance Adam.

Well it was a good night, weather-wise, last night (12-Nov-2017) in this part of Oxfordshire. Cool (3 degrees) but amazingly dry, really (85%.) And so, for once, everything wasn't covered in dew by the end of the night. After an earlier debacle with coma-corrector spacing, I've shaved off a further 0.5mm to try and tweak it a bit better, but I've also (for my sins) started a trial period with PI. I've so far eschewed this box of tools in favour of simpler, and some home-grown, things. But I'm interested in finding out more about what so many people use... even if only to understand th

The Horsehead Nebula (B33) The Horsehead Nebula (Barnard 33) is one of the best known nebulae in the night sky but few astronomers have actually observed it through a telescope. The reason for this strange state of affairs is that the nebula is very dim as it is, in essence, just a pillar of dark dust and gas – in fact we can only see it because of the curtain of relatively bright Hydrogen Alpha (Ha) emissions (IC 434) behind it. This weekend several observers have seen it for the first time through a combination of excellent conditions - especially last night (25th/26th November) - and p

Greetings Astronomers, The work on imaging my next object has begun, and as always and common to us all, I have to juggle imaging between clouds and moon phases. This is 3 hours of halpha data of 900s and 500s subs captured the night before full moon and on the full moon night through a 7nm Baader Halpha filter using a modded Canon 40D DSLR. I'm hoping to spend a night imaging 30 minute subs (when the moon shrinks to last quarter or smaller) to try to capture some of the dimmest nebulosity as well as spend perhaps another night imaging 15 minute subs through a Baader 7nm OIII filter to see wha

Hi all, This image is the complete version of the Barnard 33 system HAlpha image I posted about 3 weeks ago. The Horsehead nebula intrigued me as a kid and this image and framing was something I wanted to photograph (or fantasized about photographing) in 1991 when I was a kid using a Tasco 60mmx900 refractor on a alt-az mount. So I guess I can say that this image is nearly 25 years in the making. I did image the horsehead in the past but not framed like this with the flame nebula. Just thinking back about pestering my parent to buy be a t-adapter/ring kit and a SLR "because I was going to phot

I struggled to try to significantly reduce the quite apparent noise without losing too much detail in the clouds. In the end I decided to keep the detail ( and the noise ). Details: Orion's Belt - centred on "Alnitak". A 1.7 magnitute tripple star at one end of the belt. Includes the Flame Nebula (NGC2024) and IC434 which contains the Horsehead Nebula. RA 16h 41m 42s, Dec -48deg 48' 46". Approx. 3800 light years away. Skywatcher Quattro 10" f4 Newtonian. Skywatcher AZ Eq6 GT Mount (on concrete pier).

6th December 2015 Equipment: NexStar 8SE Time: 01:00 - 03:45 During the imaging of Barnard33 through the OIII filter using the 80mm refractor, I setup the 8SE on the single arm alt-az mount for observing. Orion Nebula looked great and bright through just the eyepiece but when using the UHC filter it was detailed and awesome. The shape of the nebula was clearly visible, the fishes mouth and the mustache shaped extends were very distinctly brighter than the reminder of the nebula. There was a lot of the nebulosity visible starting to take on the shape of the "flame" as photographed except it was

Now i dont know if i'd call this cheating - but i did a monochrome version of this because it just feels so much easier to bring out the little detail in this image without creating too much background noise in the colour version . I think i like this more than the colour version edited with PI LE, CS5 Unmodified Canon 50D, Sigma 50-500mm APO F/4.5-6.3, SW EQ5, 30 x 120s ISO 800 Sorry but cant remember what focal length this was taken at! taken in a very light polluted aberdeen

Hi! Finally my new camera QHY163C was tested under dark sky :-) I'm very happy with result, it's only 90mins of exposure (30x180s) calibrated with darks, biases and flats. My only worry is ampglow on CMOS but I will try to reduce it next time Best regards and Happy New Year! :-) Tomek

Another image from Southern France, around 5 hours of data. I left out the Ha data as this looks more natural.

Quite often I will start an image and not get time to finish it before the telescope being used has to move on. That is the case with this one, which is just 3 test exposures with a small refractor and Atik 11000. Usually the data just sits on my hard drive, going nowhere, but by chance I opened one of the exposures in Pixinsight and hit CTRL+A, and the auto-stretch feature revealed a bit more detail than I expected, so I just stacked the three images with no rejection to see what came out. Originally my intention was to frame a shot of the three main stars in Orion's belt, but the nebulo

What an epic sight the Horsehead Nebula is, I cannot tell you how stoked I am to have finally seen this. was in Andrew's C11 with a focal reducer and a 25mm plossl. Seen easily, not photographic, but so much more than a notch. Skies are so much better here at the Astrofarm in Confolens than they have been in Norfolk. Until now, I doubted that I'd ever see it having struggled in Norfolk for months. Seen by 3 other Messier Marathon participants too. Full report to follow, but just starting on the galaxies in Leo now. Chris
