  1. So I've been doing a bit of research and I think I've found out what's going on... Firstly it's not just that the focal point is quite far forward, meaning that the addition of the rotator effectively stops me from being able to achieve focus. Also there is a lot of coma and other distortion, which there shouldn't be as I am using the dedicated 0.85 reducer. I have discovered that the sensor of the camera should be 55mm back from the reducer. I measured and mine is something like 100mm back. When I bought this it came with an adaptor which connected the reducer to my Canon 450D. Howe
  2. Great. That sounds like it will do the trick. /puts hacksaw away
  3. Thanks. Thought I was going mad for a minute then.
  4. I'm focusing on the roof of a building about half a mile away. I thought it was the other way around though? ie. it's further in when focusing to infinity. I am probably wrong.
  5. Aha! This looks interesting. So this fits in place of the stock connector on the 0.85 reducer? And enables rotation?
  6. Hi everyone. I need to ask for some advice. I recently bought an Evostar 80ED DS Pro, with the x0.85 dedicated flattener/reducer. It is fitted with a Moonlite CF focuser and Moonlite stepper motor. I haven't had chance to use it yet due to weather, but I have taken it into the garden during the day and tested focus with ny DSLR attached, and I can achieve focus at about 2300 steps out from 0. So far so good. However I also just bought one of the dedicated Evostar 80ED rotators from FLO. I fitted it and tested again during the day, and now I cannot get enough inward
  7. To be honest I haven't even tried tightening the screws yet. It may be that that would be enough. Thanks.
  8. Yeah, it defintely needs locking. I attach a DSLR and if I don;t lock it goes out of focus during the session. I think it might be a consistent thing. I need to run some tests when I'm not imaging and so not under pressure. Thanks.
  9. Maybe the OTA is put on slightly differently and the weight distribution affects the PA slightly?
  10. Hi everyone. I have a skywatcher 200p with the standard focuser. I have an issue where I stick my dslr on, take photos while slowly adjusting the focus wheel until it is in focus. Then when I tighten the lock screw, to lock the focus wheel, it knocks the focus off a bit. And I have to untighten the lock screw and start again. It's very hit and miss and it can take me half the evening to get focus locked, and sometimes I can;t do it at all. Is there anything I can do to adjmust it so that when I tighten the lock screw, it doesn't affect the current focus? Thanks!
  11. Yeah they have helped me out mate, and are enjoyable to watch.
  12. Sorry, I've got an EQ5 and I'm happy with it. Just wanted to say hi, and thanks for the Youtube videos though.
