    PLEIADES 12 14 14

    From the album: Starchasing

    Classic and beautiful open star cluster


  2. From the album: Stars and Constellations

    Taken using Canon 100D DSLR on Skywatcher Star Adventurer mount. Way too much moonlight and LP to allow the necessary settings to bring out the nebulosity. Single 2 minute exposure using 300mm lens. Slightly processed in PS Elements 11.

  3. From the album: Widefield DSO

    Canon 450D all filters removed. Sigma 120-300 f/2.8 OS at 300mm f/2.8. Astronomik CLS-CCD. EQ6 guided. 19x2m subs. Processing with flats in PixInsight+PSE.
  4. Hello, Just got a new (secondhand) EOS 6D and decided that the area around Pleiades is very good test The first light was ruined by clouds (no surprises here) but last weekend was way better. Clear sky, no wind, temperature around -13C... So here is my image named "Ice and Fire" Very busy part of the sky between the famous Pleiades and California. Details in short: 6D (unmodified), 51x180s, ISO 2000, 10 sky flats, no darks, Samyang 85mm at f/4, EM-200, no guiding, APT dithering (direct mount control), APT, PI.
  5. The Pleiades (M45). This is a shot I've been wanting to do for a long time. Previous attempts were unsatisfactory because my 127 Mak has too much focal length for this object and looked straight through it and using a camera lens made unattractive spokes around the stars caused by the iris of the lens. With the 150mm Newtonian scope the framing is great and plenty of nebulosity can be captured. Also the spikes caused by the secondary mirror spider add to the image. Not perfect perhaps but definitely the best attempt so far. 44 x 75 second exposures at 400 ISO (55 minutes integration time). 46 x dark frames 38 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
  6. a play last night with Comet Lovejoy with a Canon 5D3 and 70-200mm f/2.8 lens while I was there I couldn't resist a pop at M45, the Seven Sisters
  7. Here's a single image of M45 from early this morning, plus a labelled version. Pleiades Cluster [part of] by 1CM69, on Flickr Pleiades Cluster [part of] Labelled by 1CM69, on Flickr Taken at prime focus on my Celestron CPC925 using a f/6.3 reducer with my Olympus E-510. Due to the 2x crop factor of my camera, the resulting focal length is equiv to 2960mm at full frame 35mm, hence my inability to capture the whole cluster in a single frame because of decreased FOV. Addition of star spikes in Photoshop.
  8. Hi folks, yarp - yet another re-process. I've come a long way from the original as I've learnt new processing skills. This is from the same data - I hope the result pleases. The Pleiades - M45Bob
  9. Just a quick cropped image of the Venus/Pleiades conjunction with Hyades looking on by moonlight from last night. Pentax K5 / Pentax 12-24mm lens / 1.4x rear converter / Exp. 30secs @f10 / iso 500 Ioptron tracker at siderial.

    Another test shot for brand new lens (same night as other tests of the same lens). Again, main stars and their colors are not distinct enough. Gear: Olympus E-PL6 with Panasonic 25mm/1.7 at F/2.5 on poorly-tracked panoramic head and static tripod Capture: 16 lights x 10s x 1600 ISO, master bias Site: deep country 26km from Limoges, France Sky: good (not measured, usually SQM around 21.4) Processing: Regim 3.4, Fotoxx 12.01+

  17. Also known as the Theta Carinae Cluster, The Southen Pleiades is a very bright open cluster in the Carina constellation. It was discovered by Abbe Lacaille during his visit to South Africa in 1752. Containing around 60 stars, IC 2602 shines with an overall magnitude of 1.9 and its brightest member is Theta Carinae with a visual magnitude of 2.7. This cluster of young blue stars is relatively close to us at "only" 479 light years. 5 May 2018 The Southern Pleiades open star cluster ( IC 2602 ) in Carina ( please click / tap on image to see larger and sharper ) Image details can be found here.
  18. While waiting for the main target to rise, sometimes I aimed the lens and camera to the Pleiades. The setup is Canon 300 F4 L and ASI1600MMC. Camera cooled to -15C, 350x60s subs at unity gain. Lens wide open and IDAS-P2 filter. And last year's shot with the DSLRs and the Tair lenses used as colour. Perhaps they could have been better processed, this is the first try while waiting for one more panel on Orion. It's very difficult to remove the light pollution due to the IFN, perhaps this could have been done better too.

  19. Hello, I have been spending as much time as possible outside when the weather permits practicing. My current camera is a Canon Rebel XS Astro modified by myself (IR-Cut Filter left in) w/ Astronomik CLS Clip in filter. For this shot, I used an Orion ST80 at prime focus on a Sky Watcher Star Adventurer. I did around 80 frames at 45 seconds, but it was a little windy and I was only able to keep 65 of them. I took 15 dark frames right after the lights. There was no cloud cover, transparency and seeing were both above average in my area. I don't understand why I can't see more in this shot. I think there are 2 possibilities, either I am not able to pull enough out of the image in Photoshop or my frames should be longer than 45 seconds. I know the general rule of thumb is over an hour of integration, but I should be able to see more than this at around 48 minutes. Can anyone shed some light on this please? If needed I can upload the original TIFF file from DSS. Thank you! (I know about the distortion in the corners, I was excited to see what I could pull from the image and didn't bother with fixing it)
  20. Took a series of photos of Pleiades last night just before the moon obliterated most of the sky. Quite like this first stack as it is how I would imagine you would see space from a space ship window. I know I might be completely wrong but I can dream. The second is the same stack but with a little play around with levels. The stars are blown out but the question is, Is that Nebula gases, which I know exist around this area, or am just amplifying noise etc,? Would value your opinion. If it is gases I can work on improving when the moon is less of a hindrance. Cheers
  21. M45, the Pleiades open cluster in Taurus (The Bull) at 424 lightyears. Composite of 5x10min, 42x3min, altogether 2:46hrs worth of exposure. Taken with Canon 1100D unmodified @ 300mm lens under less than optimal conditions, LP at city edge, (plus this genius forgot the LED light from the guide camera shining brightly into the lens of the piggybacked camera, grr).
  22. Still not entirely happy with this one - I ran out of time to get a set of longer exposures during the short period I had with Pleiades high enough above the Northern horizon ( 30 deg peak altitude from my location ) and since then the weather and moon have conspired against me! Description: Pleides in the Taurus Constellation ( Messier 45 ) by Mike O'Day ( 500px.com/MikeODay ) Pleides ( aka The Seven Sisters ) is visible to the naked eye low in the northen skies in the early summer of the Southern Hemisphere. It is bright open cluster of hundreds of blue stars in clouds of nebulosity that are relatively close to earth at around 430 light years distance.

  23. Hi guys! Been a long time since I last posted here. I've been on a small hiatus but now I've got more time on my hands so I can start getting into it again, hooray! I saw Pleiades is visible again at a decent hour so I thought to myself, why not try and take some shots of it again? I've assembled a thingy to create diffraction spikes with my refractor a few months back for star clusters so this was the perfect time to field test it! Results are excellent, well, in my opinion at least! C&C are always welcome. Here's the stack info: 75 x 90 second frames @ ISO 1600 0 bias frames 0 dark frames 600mm focal length f/7.5 HEQ5 Tracking Mount Modded Canon EOS 1100D Baader Neodymium Filter Stacked in Deep Sky Stacker and processed in Photoshop/Lightroom
  24. Not the most original title I know, but that's how I felt at the time too. Canon 450D all filters removed. Sigma 120-300 f/2.8 OS at 300mm f/2.8. Astronomik CLS-CCD. EQ6 guided. Processing with flats in PixInsight+PSE. 32x2m subs. 19x2m subs. It wasn't looking clear, so I didn't set up early. But it did clear up and looked too good to waste, and I was running by 10pm. My previous plan was to get some extra data on the Veil, but with a new CLS-CCD filter I had to try that out. It's more suited to broader spectrum subjects, so I revisited Andromeda and also took a quick shot at Pleiades. Neither have enough data so the noise floor is relatively high. Also the Andromeda set isn't great as I had uncorrected focus shift since I didn't pre-cool the lens enough before using it. I used the modified 450D with the new filter to gain more red sensitivity, however I suspect its noise floor is higher than the unmodified 600D (with old filter) I used previously on Andromeda. Also I think the two data sets might be too different to combine to see if I can get more information out of it. Everything was covered in dew and I packed up just after midnight.
