  1. Great news. Any plans to stock the Astronomik HA DSLR Clip Filters? I’m currently in the market for one of them...
  2. Great effort Nige! I have a very similar set up to yours except I have a modded 1100d. I haven't tried using an filters yet but this post has inspired me.... can I ask where the filter goes in the imaging trail (e.g. inside DSLR, somewhere between the t-ring and the telescope etc) and do you use any sort of filter adapter? If so can you forward me a link please to the one you use? Ive been thinking about what to get myself for Xmas and I think I've just found it... James
  3. Hi Alan, the CPC is mounted on a Heavy Duty Wedge which allows we to take much longer exposures for DSO's. I polar align using the drift method and I can easily achieve 600second exposures (as was the case with the image above). I haven't tested any exposures longer than that but I'm sure I could push it further if I tried. I have the scope fairly well balanced and its permanently set up in the obsy out the back (which helps). I then image through the SW Equinox 80 ED PRO which is piggybacked on top of the CPC1100. I also then use an Orion mini-guider piggybacked on top of the Equinox.

    My DSO Images

    A collection of DSO images that I've managed to capture
  5. Took advantage of the clear skies this week and decided to have a go at Andromeda. It's far from perfect BUT a big improvement on my attempts at the same target this time last year. Modded Canon 1100d with a Skywatcher Equinox 80, piggybacked on a CPC1100 for mount. 600s x 15, 60s x 15, 30s x 15, 10s x 15 + darks, bias and flats, stacked in DSS and then processes in Pixinsight Constructive criticism/friendly advance welcome ! James
  6. I've included a link to the unprocessed calibrated frames in my original post (one is a 600s stack and the other is 60s stack. The stars look fine in them, albeit the brightest ones are a bit saturated. But the strange hollowed out effect in the HDR image seems to be on every star across the whole image.
  7. Thanks for the replies I shall have another go later. Yes both the images are linear, well the only processing on both was a RGB alignment and slight saturation increase in DSS after stacking, prior to saving. I see what you mean though. I did take some 5s exposures to capture the Trapezium which I can add later, once I've mastered the HDR bit with these 2 sets.
  8. Try this, here's the resulting HDR Composition image What process should I be following to combine these 2 different stacked exposures?

  10. I'm still very much a beginner with Pixinsight, having recently downloaded the 45 day trial version. I've spent some time watching Harry's videos which were very useful so I've got a fair idea of how to do the basics now. Lots more practice needed though! I'm now trying to combine 2 different exposures of M42...one stack of 600s and one stack of 30s......both previously stacked in DSS. I've tried doing a Star Alignment and then an HDR Composition, but the resulting image leaves me with stars that I can only really describe as looking like diamond rings. To be honest I'm not entirely sure
  11. Mine was mix of 600s, 60s, 30s and 5s....I think the 600s x 9 were too much for the 10x of each I did for the rest of the subs....I've stacked different length subs before on M42 and achieved a much better outcome on the core (albeit a far worse final image). I'll be having another go this week (weather permitting) so may be ill increase the volume of shorter subs and see how that goes..
  12. Captured this Friday night, mix of 600s, 60s and 30s subs. Darks, flats and dark flats added and stacked in DSS. Been playing around with Pixinsight this week and this is my first proper go at processing something with it.... lots to learn but Harry's tutorial's have come in handy. The core is blown obviously and I'm not sure why but it still doesn't look quite right.... Nevermind though, it's a million miles better than I was able to achieve the last time M42 came around so I'm happy that things are heading in the right direction. As always....advice and criticism welcome please Jam
  13. For what it's worth I have this guide camera and I think it's excellent so I would definitely recommend to anyone who may be interested !
  14. Hi guys, having finally thrown the towel in on DSO imaging with an SCT (CPC 1100), I took the plunge and got myself a Skywatcher Equinox ED80 Pro. This is my first proper go at M31 from Friday night, 9 x 10min exposures at ISO800 plus 9 x darks, 20 x bias, 20 x flats and 20 x dark flats. Needless to say it's far from perfect, in fact it's far closer to totally imperfect !! However, it's a world away from the efforts I attempted with the CPC1100 so I cant wait to get out and have another go. It's not all plain sailing, the ED80 is piggybacked on top of the CPC1100 on a heavy duty wedg
  15. No problem James, these things can't be helped.

    If you could let the campsite owners know it would be appreciated.

    Take care

      Cheers Tony, email sent to the campsite. I hope the skies remain clear for you all.
