  1. Hey there. I am curious, as to what media or software you guys are using, in terms of knowing when certain alignments, conjunctions or events happen? I actually had a clear sky, a couple of days ago, when the conjunction of Venus and the Pleiades happened, but I didn't know until the day after. I even thought: "what a nice clear sky, but naaah, the moon is way too bright tonight" (I mostly shoot galaxies these days). So I am actually a bit bummed at missing that. So, what good sources are you guys using? I am mostly using stellarium, reading a bit on the forum here, and looking into SkySafari Pro (will that give any clues?). Or is it simply by chance figuring it out Thanks in advance.
  2. The Pleiades showing different temperatures in a super unfocused image (by accident). Only after looking better to this I noticed all brightest stars are there. Love it! Stars info using SkySafary6 AVX SW80ED 700D 19s ISO12800, both images
  3. 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.
  4. 30+ exposures between 1 and 60 seconds with an ASI533MC_Pro and WO61 refractor. The huge dynamic range makes this a real challenge lol
  5. Hi all, For a long time I wanted to shoot this frame, probably from the early days of my astrophotography adventure. Finally after all these years I managed to get a decent result of the 'stuff' between these two beautiful nebulae. Fairly happy with the image but always looking for improvement. I hope one day to redo this all with a mono camera and filters. Apart from NGC1499 , M45 and the Baby Eagle Nebula no idea what else is in the picture. If you happen to have an idea feel free to educate me. Some info on image and capturing: Widefield Pleiades to California. Taken over 2 nights with a total of 11hrs 25min integration. With a stock Nikon d610 and Nikkor 85mm 1.8 objective. Tracking was done with the Skywatcher Star Adventurer. Lights and all calibrations frames were stacked in DSS. Processing was done in Adobe Photoshop CC using Adobe Raw, GradientXterminator plugin, HLVG plugin, Nik software plugins and Photokemi action set. Ken

  10. 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.

  12. Hi, First post on SGL so hello everyone and thanks for all your posts. They have helped me greatly to hit the ground running with my new hobby! This is my first ever DS image taken on 4th night out with my scope. I spent the first 3 sessions practising setting up, polar aligning and imaging moon etc. Last night I nearly never ventured out because of the moon and cloudy forecast but so glad I did! When aligning my finderscope I stumbled upon M45 and decided to give it a bash. Managed around 40subs before clouds rolled in and moon came up but very chuffed with my first result! Criticisms and advice more than welcome Image + Processing: M45 Pleiades 01/04/18, from back garden in southside of Glasgow ~40 x 30sec subs 10 Darks DSS + Photoshop (Messed with curves, levels and used Gradient Xterminator) Equipment: Skywatcher 200PDS HEQ5Pro mount CanonEOS1200d
  13. Had some nice clear skies last weekend, so I simply had to take advantage of them, even though the temps dropped to -4 on the Saturday night! Thankfully i was able to just move the car a few metres and use the frost-free ground underneath to set up. And boy, what a god send Team Viewer is! I Once i was all set up, i was able to monitor it all from inside the house. Most of the neighbour's had selfishly decided to light fires, how inconsiderate of them, lol. It was quite annoying though i have to say, seeing all the smoke at times billowing across my FOV! Thankfully i stayed up late though, so i outlasted most of them It was easily the most productive 2 nights I've had so far. The skies were completely clear all night long on both nights. In the end i managed 11 hrs worth of exposure in total over the 2 nights. I still need to process the Soul Nebula subs (Ha and OIII), hope to get to that later this week, but for now here's the other object i was shooting, good old M45. So this is 2 hrs 40 mins (16 x 600s) using the Nikon D5300a and an IDAS-D1 filter. 30 Flats, 50 Bias, with aggressive dithering. Captured with Sequence Generator Pro, stacked in Astro Pixel Processor, and processed in Photoshop. I may have gone too far with the processing (i tend to do that), what do you guys think? I had an earlier version which was sooooo much smoother, but it was seriously lacking in visible nebulosity, so i kept going! Plus, i wanted to try and eek out some of the surrounding dust, which i just managed to get. I might end up reducing it by 50% in size, due to the noise, haven't decided yet though. C&C welcome as always of course! The last RGB image i did was a brief go at M42 about a year ago, and that was also taken from home using the same filter. I had forgotten just how hard RGB processing is when not captured from a dark sky! ps - I've also added a version below with some funky diffraction spikes. Just for fun of course! Although i actually don't mind them
  14. 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.

  15. 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)
  16. 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

    Taking advantage of a short break in the cloud cover. Although a thin layer is still present.
  19. I forgot to share this one last month. Between travel for business and brutally cold weather closing down my nearby imaging location in the mountains I have not had time to image this year. This was taken at the beginning of December and contains a very busy wide field splitting the constellations Taurus and Perseus. The better known DSO's are M45 the Pleiades reflection nebula and NGC 1499 the California emission nebula. The center of the image contains a dark nebula which I am not familiar with and the rest of the region is quite heavily laden in ISM interstellar medium dust. This image was taken with my unmodded T3i Information about this image camera: unmodded T3i ISO:1600 Exposures: 102 x 100s Darks: 5 ugh, mishap Bias:450 frame master Flats:35 Lens:SMC Pentax M* 50mm F1.7 stopped to F4 SQM: 21.1 Seeing: 3/5 Transparency:3/5 Calibrated and partially processed in Pixinsight and finished off in Photoshop CC 2017.

    Pleiades

    From the album: Astrophotography

    Taken with my iOptron Skytracker and Canon 70d with 300mm lens.
  21. Had scope out last night but seeing was rubbish due to moisture so I decided to piggyback my dSLR & capture some widefield shots. All images are taken at 14mm on my 4/3 dSLR, equiv to 28mm full frame. Pleiades or M45 by 1CM69, on Flickr M31 Widefield by 1CM69, on Flickr Orion widefield showing M42 nebula by 1CM69, on Flickr Thanks for looking.
  22. kit- super-tak 35/135, 1200d unmodded, Heq5 . taken from my obsyroom open window. seeing was very good uptill 10.30, then thin cloud arrived as soon as Orion cleared the horizon, but most of it staxed out. The Pleiades, 20/45 sec, iso 1600. 21.30pm. NGC1647. lovely open cluster ,often overlooked. 10x40 sec iso1600 . 22.40pm. Orions Belt with a hint of flame. 22x 45 sec and 10x24 sec. iso 1600. 23.20pm. thin cloud. that darn cloud at 23.00, i waited another 30min or so,untill most of the belt and sword had risen above.
  23. 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.
  24. Hey all, Here's a look at the Pleiades last night. Canon 7d, 400mm at f5.6 ISO 1600. 15*2 min 6*5 min This focal length is starting to test the mount, plus it was a bit windy, so I threw away around 20% of the 2 min subs, and nearly half the 5 min subs (unguided). Beautiful target though.
