  1. This is a second attempt to image the Owl Nebula - the first attempt, over a year ago, was rubbish - and though I wouldn't say I've nailed it, it does look much better and now it at least bears a passing resemblance to other pictures I've seen of it. 8 x 8 minute exposures at 400 ISO 11 x dark frames 10 x flat frames 21 x bias/offset frames (subtracted from flat frames only) Captured with APT Guided with PHD Processed in Nebulosity and Photoshop Equipment: Celestron NexStar 127 SLT GoTo AltAz mount with homemade wedge Orion 50mm Mini Guide Scope ZWO ASI120 MC imaging and guiding camera Canon 700D DSLR
  2. I lost astro dark a couple of weeks back. I thought, therefore, that I would try capturing narrowband during nautical darkness on the basis that I may as well do something with all the gear. I ended up with 6 hours of Ha and 6 Hours of OIII captured at my home observatory using my Esprit 120 and QSI 690 atop a Mesu 200 mount. Filters are Astrodon and exposures were 30 minutes each. Processing in PixInsight and Adobe Photoshop. I cropped the image slightly to eliminate a couple of brighter stars at the edge of the frame. I'd be interested to hear what people think.
  3. My first attempt at capturing the Owl Nebula. It really is a very faint object seen from London. The nebula only barely showed up in the subs. Imaging was curtailed when the scope reached its slew limit and the subs started to streak (alt-az mounts really don't like being pointed directly up do they?). 26 x 25 second exposures at 6400 ISO and seven dark frames.
  4. Hi, This is my attempt at the Owl nebula and also the first picture taken with cooled CCD camera for me. My Canon EOS500D has now retired. The image is photographed from Uppsala in Sweden, date 2013-03-13. Exposures L23x10min, R9x10min, G9x10min, B7x10min. Camera SBIG STF-8300M, cooled to -30 ° C. Telescope, Skywatcher 190MN on NEQ6-mount. Guide camera-QHY5M. Stacked in Maxim DL and then processed in Adobe Ps Cs5. Weather conditions good, around -15°C. Enjoy!

    M97 and M108 (Owl nebula). I stretched the original Tif using DSS. Hardware details: Camera: Nikon D200 Telescope: SW Evostar 120 with Baader UHC-S filter. Mount: AZ-EQ6 guided using a ST80 synguider. Image details: Lights: 91 x 3min at ISO 800 Darks: 40 x 3min at ISO 800 Lights and darks separated by 1 min intervals Flats: 40 x 1/40s at ISO 800 Bias: 30 x 1/8000 at ISO 100 Date of capture 22/01/2016 Conditions: Very clear sky with some light cloud. Seeing was good. The guiding was a bit erratic - possible bad calibration or wind. quite a few subs ended up unguided!

    I guess i need a lot more subs & a lot longer at that, still happy with how this is going though.
