  1. Very nice image Mike, looks like your experiments were a great success, really bright and luminous looking image. Rich.
  2. That's very nice, so smooth and detailed. Really good stuff. Cheers, Rich.
  3. Very nice Franck, some nice delicate details in there. Rich.
  4. Very impressive resolution there. Very nice. Rich.
  5. Great shot that, looks like that time spent with the guiding,etc, has paid off. Very nice detail and like the colour too. Cheers, Rich.
  6. The framing and the clarity of the gas structures show real promise for future data grabbing on this one. Look forward to seeing it again when you get the extra subs. Cheers, Rich.
  7. Keep it as it is, looks great to me:D Great piece of work. Cheers, Rich.
  8. The bubble is just so well define there, nice work from the two of you! Done a good job there of controlling the bright area in the bubble too. Cheers, Rich.
  9. It always amazes me that you can point a camera lens at the sky with a 6 degree diagonal FOV and have nearly the whole image full of gas. Before I started long exposure astrophotography I never realised just how big these objects can be. Cheers, Rich.
  10. Thanks Kevin, Guy and Steve. I've not tried the lens stopped down as I wanted to avoid the diffraction spikes you get with that, I should try it though to see what difference it makes to the star sizes (I did quite a bit of star reduction to try and make the nebula show more with this, I'd rather have just a handfull of stars left!). The camera is attached to the lens using an adapter from 'Mogg Adapters'. I use the Starlight (T)-EOS adapter, I couldn't achieve focus with the initially supplied ATIK-EOS adapter. There is the slight issue that the T-thread on the adapter is deeper than the T-thread on the 383, which is quite shallow... the interface I have seems good though to me. I have recently received the 1.25" filter holder that fits inside the adapter but not tried it yet, still using a DIY effort that I made while I waited for the holder to arrive. Thanks, Rich.
  11. Will be looking forward to the addition of the O3, the Ha alone is amazing, so much detail in the faint stuff... Rich.
  12. Thanks Jim, hopefully we won't have to wait too long here for some clear skies again... Rich
  13. Superb result, great colour and detail. The stars are so small and sharp, amazing without sharpening,etc Rich.
  14. Took this a few nights ago in Ha and hoping to add other channels to it when the clouds/rain move on:) Not sure I've got the levels/curves right at the moment though. Taken with an Atik383 camera, Baader Ha filter (1.25") and Canon 200mm prime lens at f2.8. Exposure was 8*15min, processed in Astro Art 5. Thanks for looking, Rich.
  15. The resolution of the 383 should be better with the smaller pixels than the 314 but you might be seeing better detail in the 314 image because it is deeper due to its bigger pixels:icon_scratch: There's always the option to bin 2x at longer focal lengths and still have plenty of pixels to play with. Nice images there and glad you're liking the camera. Cheers, Rich.
  16. Great stars across the FOV, very nice depth and details. Look forward to seeing it again if you add to it. Rich.
  17. Great capture, very pleasing on the eye with that clean background and good colour in the nebula. Rich.
  18. Nice one, there it is for all to see:hello2: Rich.
  19. Great capture, so deep, the 30min subs have worked a treat there. Rich.
  20. Thanks, Rob- It's the 8" edge scope. Cheers, Rich.
  21. Great dedication and an amazing result, so much extra fine detail to see. Rich.
  22. Very nice, good to see the different palettes of the same image, I like the HaOO image best too. Regarding the tricky alignment that you mention, if you're using DSS to stack the images you can get it to do the alignment for you, the resulting stacked channels are then already aligned when they come out of DSS. Before you stack the Ha, you select one of the subs to be the alignment reference frame (select sub, right click, use as reference frame), ideally use your best Ha sub as the reference. When you stack the Ha, the resulting image will be aligned to the selected sub. When you stack the O3 and S2, you include this Ha sub in the list of light frames, again select it as the reference frame, but leave the sub unticked so that its data is not included in the O3, S2 stacks. The resulting O3 and S2 stacked images will now be aligned to the Ha image:) Cheers, Rich.
  23. Great details throughout this nice galaxy, colour is really good too. It's often called the box galaxy and looks strangely rectangular through an eyepiece, not sure if you've seen it visually too. Very nice work. Cheers, Rich.
  24. Thanks Tim, I think I need some kind of OAG setup before I can push the subs longer at F10 but I thought I should wait for the reducer for the scope to be released first so I can make sure the OAG will work with it. Cheers, Rich.
  25. This is the first image with my Edge HD scope for some time, mainly due to the slow F10 ratio (rumour has it the reducers might appear in the summer!). Looks like there's some collimation to be done as the stars on the left side are poor compared to those on the right. I also took some O3 but the seeing was bad and I'm struggling to produce the HaO3 image, think I might need to re-take these. Exposure was 40*3min with an Atik383 camera at 2000mm, binned 2x due to the focal length/pixel size. Thanks for looking, Rich.
