  1. The Leo Triplet - a target that I needed to image again as previous efforts haven't really done it justice. This is the most successful attempt so far, largely thanks to the ZWO ASI1600MC Pro camera and by giving it plenty of exposure with not too much gain making for a smoother background and bringing out dust lanes and other details in the galaxies. 014 x 090 second exposures at 161 Gain cooled to -20°C 081 x 090 second exposures at Unity Gain (139) cooled to -20°C 010 x 120 second exposures at Unity Gain (139) cooled to -20°C 016 x 180 second exposures at Unity Gain (139) cooled to -20°C Total integration time = three hours, 30 minutes and 30 seconds 149 x dark frames 116 x flat frames 200 x bias/offset frames Captured with APT Guided with PHD2 Processed in Nebulosity, Fitsworks, and Photoshop Equipment Telescope: Sky-Watcher Explorer-150PDS Mount: Skywatcher EQ5 Guide Scope: Orion 50mm Mini Guiding Camera: ZWO ASI120MC Imaging Cameera: ZWO ASI1600MC Pro Baader Mark-III MPCC Coma Corrector Light pollution filter
  2. Despite all my weather apps predicting cloud the night was unexpectedly clear (ish) with just the glare of the Moon and some some patches of thin high cloud to contend with. I wasn't sure how much of the three galaxies would come out as very little was visible on the subs but I was pleasantly surprised. M65 (bottom right), M66 (bottom left), and NGC 3628 (top). 1 hour and 25 minutes total integration time 68 x 75 second exposures at 400 ISO 29 x dark frames 52 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: Sky-Watcher Explorer-150PDS Skywatcher EQ5 Mount Orion 50mm Mini Guide Scope ZWO ASI120 MC imaging and guiding camera Canon 700D DSLR
  3. A few more subs helped to get this image of the Leo Triplet looking a little better than it did before...just in time because the Leo Triplet is setting behind houses shortly after dark where I live. 39 x 30 second exposures at 6400 ISO taken on 13th and 17th May 2015 10 x Dark frames 11 x Flat frames 24 x Bias/offset frames (applied to flat frames only) Processed in Nebulosity and Photoshop
  4. From the album: DSO, Nebula, Galaxies, Comets etc

    The Leo Triplets - M65, M66 & NGC 3628 25.03.2017 Skywatcher Equinox 80 and Atik 314L Monochrome CCD 35 x 300 seconds stacked in DSS and processed in Photoshop CS2

  5. Well not strictly a first attempt but the first time I've really made a note of what I'm doing and also a had a new toy to play with (6" f5 newtonian) Leo triplet - largely as a test of my new scope. Skywatcher 150pds, Exos 2 (EQ5) unguided, Canon 500d, ISO 800, a single 60 second exposure (I've not got to grips with stacking yet!) Given there's no guiding, no processing, no stacking, it's a cheap mount and it was near to a full moon I'm not too disappointed with that. The next steps are to work out how to process multiple exosures properly and clean up the hot pixels from my camera, rebuild the mount to make it run more smoothly and most significantly piggy back my ST80 so I can use it for guiding.
  6. Apart from the odd 20 minutes of low cloud, it was a very clear night last night. I could not resist the coming of the galaxy season. Here is my first attempt this season quick process. ZWO ASI183mm Pro camera. 20 x 120s Lum 12 x 120s RGB Processed in Pixinsight. Sequence Generator Pro. Thanks for looking Dave.
