  1. This is the first attempt for me on this target and it's a tricky one from London. Hardly anything at all showed on the subs so I was surprised at how much detail was hiding in there. 10 x 8 minute exposures at 400 ISO 7 x dark frames11 x flat frames21 x bias/offset frames (subtracted from flat frames only)Guided with PHDProcessed in Nebulosity and PhotoshopEquipmentCelestron NexStar 127 SLTGoTo AltAz mount with homemade wedgeOrion 50mm Mini Guide Scope
  2. The Triangulum Galaxy (M33): I think at over 4 hours of exposure, taken over three nights, this is pretty much finished for now though I may add some more data if we get another clear night soon, or I might just reprocess it but I'm fairly pleased with what came out. 33 x 8 minute exposures at 400 ISO (4 hours and 24 minutes) 27 x dark frames 20 x flat frames 21 x bias/offset frames (subtracted from flat frames only) Captured with APT Guided with PHD2 Processed in Nebulosity, Maxim DL, and Photoshop Equipment: Celestron NexStar 127 SLT Skywatcher EQ5 Mount Orion 50mm Mini Guide Scope ZWO ASI120 MC imaging and guiding camera Canon 700D DSLR
  3. After doing some imaging of M31, the Andromeda galaxy, a few nights ago I thought it would be worthwhile trying an experiment with the same setup as before on a more challenging object. The Triangulum galaxy, M33, is in the same vicinity as M31 but is significantly fainter and smaller. This image is composed of 29 subs each with a 30 second exposure time. Mrs WaveSoarer did the same treatment as before but the focusing wasn't quite as good as our previous effort when she zoomed in to individual bright stars on the subs. I think that the breeze might have affected things also. However, she thought that the tracking was better so that was a bonus. The final result, again all worked up in PS, is promising but I think demonstrates that we'll need to move on now and start using DSS along with dark frames. I also think that to really get better focusing we'll need to download the longer framing and focusing subs onto the laptop as the little screen on the back of the camera isn't really adequate unless the focusing is grossly out. Anyway, from set up to packing away, and then making it to the pub for a beer with friends in our local, was all done in about an hour. Incidentally, M33 is just about visible in the finder and only appears as a faint smudge in the main telescope with a 20 mm EP.

    M33

    From the album: Deep Sky

    This is M33 - the Triangulum Galaxy taken on bonfire night, 2012. It was a bit misty (maybe thanks to the fireworks!) and so the subs were rather noisy. This is 5 1/2 hours of Lum data in 10 minute subs, TS90 APO triplet f/6.7 taken with an Atik 460ex, guided with IMG0H and PHD.

  5. From the album: Deep Sky Objects

    I'm pleased with this image given that the first subframe was smeared badly due to tracking errors caused by cloud. That cleared and stayed away until 5 minutes after the last frame that I took. I'm delighted with the detail that I captured, especially that of NGC604 (the red blob in the lower right). M33 is a spiral galaxy approximately 3Mly from Earth and is part of our local group of galaxies. It is believed that it is a satellite galaxy of M31 (the Andromeda Galaxy) due to their gravitational interactions. NGC604 and NGC595 are large H II regions in the galaxy and are highly active. NGC604 is approximately 1500 light years across, over 40 times larger than the Orion Nebula and over 6300 times more luminous.

  7. Hi all My recent rendition of the Triangulum Galaxy (M33, NGC 598) in the constellation Triangulum at about 2.5 million light years, luminance, 20x5min., Atik 314L at -10 degrees, SW200P, guiding w/ 9x50 finderscope and PHD2, no flats, altogether 100min. worth of exposure. I had to do an awful lot of wizardry to get rid of light pollution effects. Andy
  8. The Triangulum Galaxy, or Messier 33, is a spiral galaxy in the constellation Triangulum, and is visible to the naked eye under dark sky conditions. Unfortunately, deep sky objects like this are not visible to the unaided eye here in the Coachella Valley due to city light pollution. I was able to capture this on 9-30-16 during the new moon phase, and am very happy with how it turned out. I was able to get up to 240s lights with the wedge, and I could have gone longer that night. Definitely a first for the wedge and I lol we go back and forth 3 hours total exposure time 37x150s lights 12x180s lights 13x240s lights 68 darks 40 bias 38 flats Equipment: Celestron Nexstar 6se + wedge 6.3 focal reducer canon 450d asi120mc-s guiding http://coachella-astronomy-astrophotography.blogspot.com/2016/10/triangulum-galaxy-m33-backyard.html

    Since the skies are not playing along, might as well learn how to process these images better, so old data but reprocessed. Canon 7D with Canon 500mm f/4 L IS @ f/4, ISO 1600. Astrotrac TT320 mount. 35 x 60 second Lights 25 x Bias 25 x Darks 25 x Flats Taken near Horncastle in Lincolnshire

  11. It's not that I haven't been taking images, I just seem to have been too busy to process them. This one was taken at the recent Kelling Heath star party, captured over a couple of nights. Normally go for 10 minute subs when in the field, but thought it wouldn't hurt to go for 20 mins for a change. The skies were not brilliantly transparent, nor especially dark for Kelling, but at least we got some decent views. Never really sure which colour scheme looks best on galaxies, so in the end just went with what I personally prefer. Telescope is Skywatcher 150ED and as always just take a one shot colour CCD (Atik 460ex) away to star parties, just in case we only get a few hours of skies, but I managed to get three 30 minute pics with a 460ex Mono and Pentax 75SDHF which seemed to want to come home with me from the trade stands 28 x 20 mins OSC + 3 x 30 mins Ha. Full size available via the astrobin link. Thanks for looking Tim
  12. Managed to capture about 65 (180s each) useable subexposures of the Triangulum Galaxy on my holiday. Mostly luminance but apparently enough RGB data too to bring out some colour. Not bad considering I didn't take any flat frames for calibration. More info here: https://en.wikipedia.org/wiki/Triangulum_Galaxy
  13. When I just got my first telescope back in December, the Triangulum galaxy was one of the first objects I was trying to find. But with my lack of knowledge of the sky, and the brightness of certain objects, I never succeeded, and before long it wasn't in the sky at night anyway. I had a clear night a few days ago, and my initial target (Bode's Galaxy) went behind a tree, and some clouds obscured the western sky. Checked stellarium to see what else would be of interest to capture, and coincidentally M33 had just risen above the roof of my house. Wasn't sure well it would show up in images, as I seem to remember it being a galaxy that really shines when imaging Ha. But even in short exposure test shots, I could see the core and line it up, so I gave it a go! I had a few technical difficulties during the night, with my laptop not recognizing the port that my mount was connected to, so guiding wasn't a possibility. At least not without restarting the mount/pc, which I didn't quite feel like, so I went with 2 minute unguided shots, with which I accumulated 55 usable ones (Like 6 of them had satellites go through them, but I used them anyway. And if you look closely they are still barely visible). I was able to pull more out of it than I expected, and this is definitely one I will revisit as my experience and capabilities grow!

  14. I've tried taking this galaxy about 5 times now. My first image of it almost 5 years ago was/still is brutal. Like the Avatar Galaxy. Completely blue using a stock 5Dmkiii. lol. Well after years of trying I've finally taken a series that I feel is a step forward. Getting close to a few pictures from others I've really admired and been inspired by over the years. I think this one is gets me a bit closer. 15-300 second lights @ ISO800 25 darks. Median/Mosaic method staking in DSS. Then tweeked in PS. I need more lights I know but every time it's clear now the moon is out every single time. Like clockwork it seems. Oh well. Hutech spectrum enhanced Canon 700D/T5i with an AT8IN Newt at prime focus. Let me know what you think of the final processing.
