  1. Regardless of the mount, an adjustable chair or ironing chair will be great help. I use mine to sit at various heights or lean against the back, while standing, or just to put one foot on it, while I stabilize my body by putting my elbow on the raised knee.
  2. So it looks like that this is what you actually need : https://m.aliexpress.com/item/4000637525024.html?pid=808_0000_0101&spm=a2g0n.search-amp.list.4000637525024&aff_trace_key=9b4893f2508443c08db65c242553ed6e-1579111608727-00346-VnYZvQVf&aff_platform=msite&m_page_id=7577amp-UfuZRWmpDhc_EeyQg_4kCg1579547114977&browser_id=2ce6b9f96904439ba06875ab61a4aac1&is_c=N
  3. Have you found a solution? If not, I hope this helps :
  4. The fact is that you already have a powerful scope(20", wow!). You could try EEVA with a zwo asi 294 or an attik infinity paired with an 8", F/4 scope and you would see more than the 20"...but EEVA with a camera and a 20" dob is going to be very (extremely) difficult to track an object and not very rewarding fov-wise, unless you are hunting for tiny and faint galaxies. Is your dob goto with extremely good tracking??? So, if I were in your shoes, and already had considered of splashing an extra 3-5.000 £ to upgrade to a 28-30" dob, then I would definitely go with a proper NV device gen3 or gen4 (Gavstar and his gang know more about those "proper" specs). That way, there is no need for excellent tracking, big fov with a reducer or afocal, no laptop/cables, and a look-through-the-Eyepiece effect.
  5. I am starting to read a bit on scts and there are some complex variables on visual backs, or add on focusers, as the scope's focal length changes. I am sorry, it looks like I can't help you as I am not sure exactly how these scope's work. I would suggest to open a new thread to one of the imaging subforums, asking how others have connected their cameras to a C8 edge. I am sure others use this scope for imaging with large sensors as yours, and they will give you a hint. Then you can see if you will use an off the shelf solution, or DIY one accordingly.
  6. I see that your c8 has an 1.25" visual back. I am not an sct/mak person, but it looks that this scope is optimized for 1.25". I guess you could fit a 2" visual back or make an adapter but you will suffer from vignetting, as the inner tube will still be 1.25". Why didn't you get an 1.25" filter?
  7. No, no forget what wrote before about sct threads. Your ASI071 has T2 threads/connection interface, right? So you can screw the above mentioned aliexpress nosepiece directly to your camera. Then you screw the 2" filter on the nosepiece and insert it in your scope's 2" focuser.
  8. I am not exactly sure what you mean. If you have a 2" filter, you screw it in front of a 2" nosepiece. The filter as well as the nosepiece have m48x0. 75 threads.
  9. The sbc2000 is an analogue camera. It connects via bnc to rca cable directly to a TV monitor. Or you can use a frame grabber and connect it to a pc with sharpcap
  10. Yeah, I like it too. It looks like those NASA images, very "scientific" look. Very nice image, as always Avani!
  11. I have also found this, if you don't mind the waiting. https://m.aliexpress.com/item/33013757839.html?pid=808_0000_0101&spm=a2g0n.search-amp.list.33013757839&aff_trace_key=&aff_platform=msite&m_page_id=3154amp-UfuZRWmpDhc_EeyQg_4kCg1579027832458&browser_id=2ce6b9f96904439ba06875ab61a4aac1&is_c=Y
  12. If not, look for something like this: https://www.baader-planetarium.com/en/accessories/adapters-imaging-accessories/2-inch-sc-thread/baader-2"--t-2-nose-piece-and-camera-adapter-(same-as-used-by-sbig)-(t-2-part-16).html
  13. I see that it comes with T2(almost m42) connection and T2 to M48 adapter. So it looks like you need a 2" nose piece (threaded for filters) with either T2(or m42) threads or M48 threads.
