  1. Thank you. I'm definitely sticking with my reflector... I've gone for the Skywatcher aplanatic. If I'm ever tempted by an f/4 imaging scope then it'll be good for that too 😊
  2. Hi all, I'm struggling to decide on a coma corrector for my Skywatcher 200PDS. I am still fairly early in my astrophotography journey (using an EOS 550D) and have the expected comet shaped stars outside the centre of images. Occasionally I also do visual observing so if possible I'd like to be able to use the CC for visual too. I've been looking at some options but when I google I seem to find significant negatives associated with each. For example, the Skywatcher 0.9x CC, I've read that it requires the focuser tube to be wound in so far as to take bite marks out of stars, and also that it doesn't do a fantastic job of eliminating coma across the whole image. Sky-Watcher 0.9x Coma Corrector | First Light Optics Secondly I looked at the TS GPU 1.0x CC, which I understand would give a better corrected image (and I'd prefer to stay at 1000mm focal length) but I understand that this also impinges on the light path due to its length: TS 1.0x GPU Superflat 4-element 2" Coma Corrector | First Light Optics Finally I have looked at the TS 0.95x CC, which I see has an advantage over the TS 1.0x in that it's shorter and doesn't impede into the light path, but I've read that it introduces some spherical(?) distortion meaning that you can either focus on stars in the centre of the image or the outside but not both. TS .95x Maxfield Coma Corrector | First Light Optics I'm wondering if anyone can share their own experiences with any CC with the Skywatcher (or another) f/5 reflector? I'm not necessarily expecting absolute perfection, but I need to avoid spending say £200 on a corrector and being disappointed enough that I later have to go out and buy an even more expensive one later. Many thanks.
  3. Thanks for the detailed feedback, I will give this a try. I need to get to grips with layer masking but I can see how useful this will be 👍🏻
  4. Thanks for the feedback tomato, I think you're right 👍🏻
  5. Hi all, I'm fairly new to imaging (this is only my 3rd DSO capture, after M51 and M13) and I consider my kit to be at the budget end of the scale. That said I'm learning a lot from others posts and experiences which has helped me up the learning curve a lot. This was 31x90s with a Skywatcher 200PDS on an NEQ6 mount, Canon 550d, Altair 60mm guidescope/GPCAM2 mono guide cam, 50% moon and somewhat murky sky conditions (there was a large halo visible around the moon for a lot of the time). I took only 5 dark frames (it was very late on a school night) and no other calibration frames. Processed with DSS, Affinity Photo, Astro Flat pro, and a fairly gentle application of Topaz Denoise AI. It took a few goes at processing to find a balanced image, I still have a lot to learn with respect to techniques such as star masking, use of layers etc. My next purchase will be a coma corrector, if anyone has experience with either the Skywatcher or the Baader corrector with this scope then I'd be very grateful to hear your experiences. Thanks for looking, Rick
