    orion nebula

    Took this last night in a rare beak in the clouds, still a work in progress and the moon was close. it was also a bit of an experiment on how my L pro max filter would help with moonlight, the answer is...quite well actually! the rest of the moon glare was mopped up in astro pixel processor. 55x60s, flats, darks and bad pixel map applied. stacked and processed in APP and final touch up in PS. Still a work in progress and i'll add more data as and when i can
  2. After being sick for what feels like an eternity, followed by two weeks of clouds and wind, i simply could not just let this night go as it was said to be yet another week or two with clouds on the way. With my main scope not quite ready for use yet, i quickly hooked up the QHY5L-II-M to a canon 50mm lens, attached a 7nm Ha filter, and started looking for a decent target. I didn't need to look long before i saw Orion, and then it was set! As the moon is currently 78% lit i must admit i was a bit worried, but i think the end result turned out OK, especially considering the relatively little data of just about 1 hour. Exposure is 13x 300s (and 35x 30s for the core of M42) with the QHY5L-II at gain 12. The lens is a Canon 50mm F/1.4@F/2.8 Darks applied to 300s exposures, but no flats or offset. Stacked in DSS, processed in PS and cropped to 16*9 size.
  3. Tried capturing M42 and horsehead nebula last night with my new Astro-modified EOS Rebel XT. During post processing I noticed these weird spots and lines across the image. Would you happen to know if this was because of the mirrors of the telescope (i.e. dirty mirrors) or is something wrong with the camera? What's weird is that this 2 images were taken with the same exact camera at the same exact position but some artifacts visible on M42 did not show up on the horsehead nebula. Btw I checked the mirrors of the telescope but I cant find the weird long spots
  4. Had a few hours of clear sky on Tuesday so managed to get some data on M42. 20x 2 seconds, 125 x 20 seconds and 6 * 60 seconds before the mist rolled in. (sigh) Captured with Kit in sig, stacked in Nebulosity and then combined in Gimp with the "Exposure Blend" Plug-in to HDR the images together. First time I used this plugin and was impressed on how easy it was to use. It needs some flats to get rid of the gradient but thats for another day when its not too cold. Cheers John

    the great nebula in orion.

    sketch 17.11.12,gel pen, 3b pencil.becuase of dew issues had to switch between x48 and x66 ,so scale may be a tad out ,(nothing new for though ) its hard sketching when your fingers are numb .
  6. ...It's enought to celebrate, heck it's enough to get drunk I say...! Yesterday it's was clear and so I had to make the yearly M42 image, it's already late for it as it's getting behind the roofs for me but even so i managed to get 7x10 min. subs and another 10x30 secs for the core, cooked it all an there you go, a clean and detailled Orion nebula The image is resized to 50% resolution but still there's plenty of details to take in, check out the trapezium fully resolved, in the full resolution image there's even E and a hint of the F component there at only 800 mm f/l...cool https://www.flickr.c...eposted-public/ Hope you enjoy, Cheers, P.S: Thanks to Jerry Lodriguss for the tutorial in PS, I allways get at it when processing images of M42...as I forget how to do it every time

    My first M42 (:

    Been really busy with university applications lately, but after watching Star Gazing Live last night I felt inspired to brush the dust off the scope and get imaging. Didn't get nearly as much exposure as I'd hoped due to mechanical problems, but was very happy with my polar alignment. Almost getting the hang of this stuff! Anyway here it is, my first go at M42, in JPEG form, with some very quick and basic post processing in DSS. Not happy with the clarity of the image, it appears hazy to me? And the core appears kinda burnt out. All feedback appreciated(: Scope: Skywatcher 200P Camera: Sony Alpha A-57 25 lights at ISO 1600 and 30s each. 12mins 30secs exposure time. 28 darks No flats or bias

    Orion & Running Man Nebulae

    First light for my new Sky-Watcher Explorer-150PDS (a good way to start the new year). This scope is much better suited to Deep Sky astrophotography with its f/5 aperture and with its 150mm mirror and a nice, wide 750mm focal length. The night was spent mostly getting to know the new beast (working out balance, focus, and guiding) so a relatively easy target was chosen for a test image and our old friend M42, the Orion Nebula was the obvious choice (also it was a full moon, a bit windy, and not the clearest of skies). It's going to take a bit of getting used to but I'm happy to report that it does exactly what it's supposed to do. Exposures can be much shorter now which makes guiding issues less frequent. There are still a few wrinkles to iron out (like how to use a 1.25 inch light pollution filter and maintain prime focus) but on the whole it makes imaging much less laborious. I expect images to improve greatly over the next few months as it becomes more familiar. 48 x 20 second exposures at 400 ISO (16 minutes integration) 64 x dark frames 24 x flat frames 21 x bias/offset frames (subtracted from flat frames only) Captured with APT Guided with PHD2 Processed in Nebulosity and Photoshop Equipment: Sky-Watcher Explorer-150PDS Skywatcher EQ5 Mount Orion 50mm Mini Guide Scope ZWO ASI120 MC imaging and guiding camera Canon 700D DSLR
  10. First, I'd like to say that I'm in wet diapers as far as imaging goes, just making a few baby steps. Tonight was clear and not as freezing cold as has been recently, so I took the kit into the barnyard where I have a fairly decent sky. I just added Bob's Knobs to my Edge HD 8", and had done an indoor collimation; I wanted to fine tune it outside as one goal of observing tonight. Another goal was trying out my new WO GT81 on the Moon, I haven't had the opportunity to use it for lunar because of recent weather.....and no Moon. So, one of the last things tonight was to swing over to M42 after the Moon got too low to observe. I used the frac to observe wide-field for a while, then put the Edge on the mount; to check collimation I swung over to Castor, and clearly split it with a 25mm Plossl. Then I went to Capella, defocused so I could get the 'donut', and it was so perfect as I closed it down while focusing I left the collimation as it was. Skewing over to M42, I started with a 25mm Plossl in a 2" diagonal and worked my way up, ending with my 2" 2.5x Luminos barlow and a 13mm Ultima EP, giving me 385X. Visually, I could split 'E' and 'F' in the Trapezium, so I thought I'd see if I could get an image through the EP with my DSLR, since the Ultima is threaded for a T-ring. This is a single image, 2.5 seconds at ISO 6400. Less exposure did not bring out 'E' any better, and 'F' is showing as a bulge in its companion. More exposure hid both as the Trapezium stars were too bright.
  11. Captured back in early October, I didn't pay quite enough attention to the framing - I should have moved the camera up and right a bit and I could have gotten the whole belt in the picture... the headline stuff is in there though, M42/M43, Horsehead and Flame etc 10x 200 second subs taken with a modified Canon 650D through a Borg 55 f/3.6 (focal length 200mm). There's a load of red stuff in there that needs more exposures (or slightly longer ones) to show more off so I will redo this one and frame it correctly... or do a mosaic of Orion or... well, it'll depend on the number (or lack) of clear nights!! Unfortunately there are haloes on Alnitak and Alnilam, I may have a solution for the next time I cover this area Processing wise I'm going to have to sort out shorter exposures for the Orion Nebula and longer for the rest...

    Orions Sword...

    Hi All, I was lucky enough to have one clear night in between cloudy and rainy weather. It happened to be a moonless night, so between 9pm and just past midnight I grabbed the final subs I needed to finish the NGC1365 barred spiral image (still to be finished-processed) and after those subs were done I wanted to start to image the whole of Orions Sword using my 80mm f6.25 refractor. I captured an hour of 210 second subs, an hour of 180 second subs, 30 mins of 30 second subs and 15 minutes of 15 second subs all on the full spectrum modded Canon 40D at ISO800. For the final processing I selected only the best subs, and thankfully most were near perfect (for my average standards), resulting in me only throwing away a total of 15 minutes of data. The next night I get a another imaging session at Orions Sword (hopefully still when the moon is not lighting things up), I'll grab a stack of Halpha and OIII data to add to this project. I'm curious what the narrowband added to this RGB will result in. Clear skies, MG

    2nd M42 of my First Attempt

    From the album: First Attempts at Everything

    My first M42. I think I used a 135/200mm lens on a NEX 5N. Not sure.

  14. 9th/10th November 2015 Equipment: 80x500mm refractor Time: 22:46 - 00:40 47 Tucanae: showed a fuzzy patch with a distinctly denser/brighter core through a 40mm eyepiece (13X magnified). The 11mm (45X) eyepiece started to show granulation through out the globular cluster. The view was quite faint but noticeable and distinct. The very obviously brighter core gradually became fainter and more disperse toward the edges of the globular disc. The edges were noticibly irregular. NGC265 in Hydrus, dense star field just above beta Hydrus near east of 47 Tucanae. Heaps of faint stars but no nebulosity. The orange star that reminded me of the Sagittarius supernova during last binocular observation is in constellation Reticulum, quite possibly alpha reticulum, right place and brightness, note that gamma reticulum seems orange on star maps. Cluster in Sirius that I spotted last time I was observing is M41. A open cluster of stars, quite sparse and spread out cluster. Easily visible in binoculars and the 80mm refractor. The Pleiades are looking awesome as usual, about a hundred stars visible, and the whole constellation visible in the 40mm eyepiece FOV. This is one object that I usually spend a fair bit of time observing. This view is one that needs the least possible magnification with the highest possible light gathering power, so the 80mm scope at 13X through the 40mm eyepiece is ideal... Atleast in my tool box. Orion Nebula shows the whole Orion's sword in the 40mm eyepiece at 13X. This is definitely a view worth spending a bit of time observing. The running man nebula is very faintly showing through, but not anywhere near as obvious as the Orion Nebula. Increasing the power to 45X with the 11mm TV Nagler reveals more nebulosity and the trapezium is very obvious. Filters: Celestron OIII and Lumicon UHC filters seem to cut away too much light in the 80mm scope. There is more contrast through both but I preferred the view without either filter. The Celestron UHC/LPR and Seben CLR filters did a better job in showing more nebulosity as well as increasing the contrast. Both had their advantages so it's hard to say which did a better job, but if I had to choose, I'd say the UHC/LPR had slightly the edge on the darker parts of the nebula. The OIII and UHC filters are both too aggressive for the 80mm. Equipment: NexStar 8SE Time: 02:00 - 03:40 From approximately 2am, when the 80mm frac was setup to image the Orion's Sword, I wanted to compare the view in the 8SE to the 80mm refractor. First I framed up on to the Orion Nebula, without the UHC filter the nebula glow was very obvious and the stars with in and around, such as the trapezium, were bright. Looking through the 40mm and 11mm eyepieces with and without the UHC filter, the nebulosity was quite obvious, the "moustache" and the fishes mouth were obvious with detail visible that was not visible in the refractor as expected. That said I do remember a more detailed view of the Orion Nebula in the past... Especially using the UHC filter. The second object I located was the globular 47Tucanae. In the 40mm eyepiece the globular did not look any better than in the refractor so I replaced the eye piece to the 11mm Nagler. In the Nagler the globular was still quite dim but I did start to see granulation within the globular, but I was expecting to see the globular as a brighter object than what I'm seeing. I put the reason to seeing such dim views in the globular and the Orion Nebula to the fact that I had to keep adjusting the autoguide star on the laptop screen, even though the screen was turned down to minimum, I figured that the white light was still bright enough to ruin my night adaption.... Then I thought, have a look at the corrector plate... Sure enough, nearly totally covered in dew. Oh well the observing part of the night is over, next time I'll have to run a RCA cable from the CGEM dew strap controller to the 8SE on alt-az mount and try these objects again. Hopefully in the next week there will be at least one more clear night before the moon lights things up again. MG

    orions sword mk2

    reprocessed. i split the channels and ajusted on the own, as advise by MG. i think its looking better its got more detail now. feel free to have a play. taken with ed80, sony alpha. 20x 25 second shots iso 800. thanks for looking clear skys charl.
  16. My wife Janie is very heavily into cross-stitch and produces beautiful work from photographs (normally dogs!) using patterns that I produce for her using special software. Her latest project is from one of my deep sky images and one of her favourite objects, the Orion Nebula. The 'resolution' is a pretty appalling 216 x 216 stitches but when hung on the wall and viewed from about four feet away, it will look like a photograph. As usual, I have produced a mock-up for her showing literally every stitch that will be sewn using 82 different silk colours! For the fun of it I will post up WIP images but here is the mock-up for starters (the image might need to be clicked on to show the stitches rather than just an interference pattern!):-

    M42 plus M43 - Unmodded DSLR Image

    From the album: Deep Sky

    M42 - The Orion Nebula, plus top left M43 - De Marian's Nebula (aka "The Running Man Nebula"). This is 30 x 30 second exposures, plus 22 x 320 second exposures in an HDR composite, taken 11th Jan 2014. Again I was battling a nearly full Moon as we seem to get nothing but rain around here when the skies are fully dark! This image was processed entirely in PixInsight. I hope to get some longer exposures to try to capture more of the surrounding dust. Imaging: Sky-Watcher Evostar 80ED DS-Pro + 0.85x, Canon EOS 500D (Unmodified), Hutech IDAS LPS P2, APT - Astro Photography Tool Mount: Sky-Watcher NEQ6, AstroTortilla, EQMod Guiding: Orion ST80, QHY 5, PHD guiding Processing: PixInsight Date: Jan. 11, 2014 Lights: 30 x 30", 22 x 320" ISO 400 Darks: 109 Flats: 102 Bias: 330

  18. This is the result of a stack of images of the core of M42 that I took in February. I'm a new to DSO AP and not experienced at all! I have tried to do all sorts of things with the resulting tiff file from DSS (10 x 30 sec lights + 10 x 30 sec Darks + 5 Bias frames using an unmodified Nikon D7200 at ISO 800 on a Starwave ED80). I'm now being patient and slow and followed a PI workflow and I did a little PS to further reduce noise. Thought I'd risk showing it and hope someone can comment on how to improve my new technique in the future. Thanks for looking, R:)
  19. I had a few hours free last night, which remarkably coincided with clear skies, so I had a nice little session from around 8 until 10.30 ish. The moon was an obvious target, and I spent a decent amount of time panning along the terminator enjoying the views. I was rather obsessed with trying to spot craterlets on Plato, although I'm not sure whether last night was the best phase or not. I managed a grand total of two with a suspected third, not amazing! The seeing varied from fairly decent to fairly wobbly depending upon whether it was over the neighbours garden or house! Next up M42 obviously. Even without a filter the nebulosity showed well, clear tints of green to my eye. Switching from 24mm Pan to Nag Zoom showed the Trap at between x123 and x246. Whilst the E star was fairly clear at times, F was nothing more than a 'might be' every now and then. I know the scope is capable of it, the seeing just isn't a lot of the time. I tried the binoviewers out too, to see whether they made any improvement on the Trap and Moon. The Trap was a no, I think E was slightly harder with the binos, and the Moon was an unfair comparison because it had gone over the neighbours house. Will repeat the exercise under better conditions. I then made a start at a few Carbon stars, having added a number of lists to SkySafari. I find these lists very handy as the basis for an observing session and highly recommend having a look at them if you haven't already. Sorted by transit time I picked off a few without too much slewing. Hind's Crimson star kind of stole the show, such a lovely deep red colour. In comparison the others I viewed on the list seemed far more orange but I'll persevere and see how I get on. WZ Cassiopeiae appeared on both the Carbon stars and the coloured doubles list, a quite wide pair at 57.7", one orange and the other white. Similar brightness at mag 7.1 and 8.3 BL Orionis and V613 Monocerotis were the other two I got, fairly unremarkable I found but still rewarding identifying them in the star fields. Sigma Cass and Iota Cass were the last two doubles that I picked. Sigma was, I think, a new one for me. Nice tight (3.1") uneven double, mags 4.88 and 7.24. To my eye they looked similar in colour, white. Iota is a lovely one as we all know. Not something I view very often, must try harder, but at x123 with the Nag Zoom the three components were beautifully resolved. I'm sure I could have used lower mag but didn't bother changing eye pieces. Higher mag increased the split obviously, but somehow I preferred the tight star shapes and split at the 6mm setting. So, nice little session with the Tak/AZGTi setup which is my usual these days. Lightweight so easy to setup and alignment quick and easy. Grubby little iPhone shot attached, plus some detail of the SS lists I have loaded.

    M42 orion neb

    M42 orion neb. woke at 4.45am got a qwick snap before the sun rose, 5x10sec staxed, didnt have time to sort tracking because it was slipping out of view of my obsy window so could only get 10 sec subs and out of 24 5 where only useable. taken with ed80 and sony alpha iso 800, staxed with Regi. thanks for looking clear skys charl.
  21. As it has been a number of years since i have managed to get out under the stars (having had two small children in between) i thought i would use an old friend to get back into deep sky. M42, about 12x6 mins lights, darks to match. Dss and PS to tweek. It was such a nice feeling to get out there, a dream session where it all worked as it was supposed to and not a cloud to be seen. Had a look at Venus as well but my views of Mars and Neptune from here were pretty poor. nice to be back!
  22. Hello, I hope you are all having a good Christmas and will have a Happy New Year. This is my first official image from my shifted and rebuilt observatory that I am now sharing with my brother in a much darker location. To get to this point has taken nearly two years, so even though the image has some registration issues and camera artifacts, I am happy to be at this stage. It is also 3and 1/2 years since I really processed a full image. I started an M17 image which will have to be finished next year due to the bad weather we have had. Onwards and upwards! Anyway, I hope you find something to like about this image of M42. Large image and technical details can be found at https://secure2.pbase.com/grahammeyer/image/166759195/original.jpg Thanks for looking! Graham.
