  1. Off-Axis Guiding - Vibration ?

    Eh? Just remove the canon t adaptor and insert an oag instead. This will work perfectly with your telescope! HTH.
  2. But if you're not in focus, it's not gonna be 133mm. In your case I'd say it's more than 133mm. Focus by moving the mirror -I think- toward the corrector. HTH.
  3. Hi. Try moving the camera closer to the back of the telescope and/or get the focus as perfect as possible. Is the OAG pushing it too far away perhaps? HTH and clear skies.
  4. EXOS-2GT

    Yes, that will do it. But you could get a much more sensitive camera and a proper guide telescope, saving over half your Orion outlay;) HTH.
  5. EXOS-2GT

    You can use PHD2.
  6. EXOS-2GT

    Looks like it. But your guide camera must have a st4 socket to connect to the mount. It's: usb: computer to camera st4: camera to mount HTH.
  7. Oh dear... oh dear....

    Nonsense. Wrap a towel around it and and use it as one of those things that keeps out the draught at door-to-floor interfaces. HTH.
  8. m34

    Hi everyone. Still haven't the dedication to stay on one target all night, so I cut short my galaxy snaps to have a go at this and convince myself once and forever that OAGs are the way to go. Effortless stars! 700d on nt150l 20x2minutes @ ISO800
  9. OAG + dslr

    Hi everyone Quite a bit of interest in OAGs recently, so I thought I'd post my result. Slim a few sizes from your stars, a few kilos from your mount and guide for as long as your sky will allow. Recommended. HTH and clear skies.
  10. Hi everyone. 2 1/2 hours this time with a bit of glow around the galaxy appear. I forgot to check the histogram. At 5 minutes, it was well across to the left; could have doubled the exposure easily. Anyway, still not as close as I'd like but this is the best I'm gonna be able to do at 1200 I think. Thanks for looking and as always any suggestions for improvement most gratefully received. Cheers and clear skies. 700d on nt150l @ ISO800
  11. Off-Axis Guiding - Vibration ?

    Hi. Not sure whether this is the same elsewhere but astro clubs here -I use the word club loosly- are a great source for trying out stuff without committing to a purchase. I too was convinced that my setup was flex free until I tried an oag. No more fighting with those awful star reduction algorithms!
  12. EOS 500D and Powered Hub

    Hi. Don't know which hub it is, but they're probably all similar. I run a Canon 700d, asi120mm and an eq6 via a powered hub but without the power -got the powered hub version just in case I needed it. It's plugged into a usb3 on the pc. Apart from the mount, any order works. Try with usb3 with and without the power? HTH.
  13. Perseus Double Cluster

    Hi. Excellent shot. One thing you can do to keep more detail and fainter stars is by not making the sky so black. You can do that in curves or levels; leave a gap to the left of the histogram as you stretch it rather than hard up against the left edge. HTH, cheers and clear skies.
  14. Datyson T7 - anyone?

    Hi. It just works. It uses the same soft- and firm- ware as the asi120; you can upgrade/downgrade using the native software and firmware from the zwo site. I also have use of an asi120 and with the standard drivers installed, it's a drop-in replacement. I have the monochrome version and am using it in an OAG; guidestars not a problem. HTH.
