  1. Hi guys, Was this talk recorded such that I can catch up with it ? ATB, Andy
  2. I think you guys are doing a great job with these web lectures, the varied content has been so interesting. It has now become (for me) a bit of a Sunday evening institution that I look forward to, but I do appreciate the effort needed from you to make it each week and if the frequency reduces then that's fine. ATB, Andy
  3. I always use the MDS ADM kit for guidescopes, finder, counterweight system and camera bracket and have never had an issue with any of it. Both Anthony (ADM) and FLO are quick to respond to any questions and make sure that you get the correct fitting parts. Andy
  4. Ian's a pleasure to deal with, honest informative advice regardless of whether you are buying from him or not - sadly so rare these days !! Andy
  5. As Dave has already said you do not need to calibrate if you haven't changed things from session to session. I think that you do however need to either enter manually or have Maxim to be able to read the mounts declination position (this is my setup) so it can automatically compensate for different tracking rates at different positions in the sky. You can also use the auto flip function to take into account the meridian flip. ATB, Andy
  6. No contest for me it's Maxim every time. I started using PHD and found that some nights it would run perfect straight from the off, other nights I couldn't get it to guide no matter how much tweaking I did, bottom line was I wasn't prepared to lose valuable imaging time fighting with guiding software. Maxim has run absolutely spot on and reliably from the day I started using it. I appreciate that PHD is free and Maxim is not cheap but Maxim does numerous other things in addition to those already mentioned in the thread which may help one justify the cost. ATB, Andy
  7. I can understand the concensus that screwing the Lodestar onto the thread is probably the best solution but when I did this and the Lodestar was tight the CCD chip was never square on to the light path coming out of the support pillar hole from the prism. I've gone with the 1.25" adaptor which grips the lodestar as if it was an eyepiece and can now get all the CCD illuminated. Had no issues with actual Lodestar flexure. Andy
  8. Olly, No need for a photo, I found the one you had previously uploaded on a separate thread. ATB, Andy
  9. Olly, Any chance when you get time of a quick photo showing the strap fix that you have used on the SX OAG, I'm wondering if this is one of the issues I have with my SX slimline OAG ? Many thanks, Andy
  10. Give Bern at Modern Astronomy a call, you'll get good advice on what you need and he'll probably have just the connector you need. Andy
  11. Many thanks for the confirmation. Andy
  12. A good informative thread. I have a further simple question - once both the imaging camera and guide camera have been adjusted and are both in focus can the optical train then be altered by say adding or removing a focal reducer then you just simply refocus the imaging camera and do not have to touch the guide camera ? ATB, Andy
  13. Many thanks to you guys. I'll have a go as you have suggested, however it's extremely time consuming and a right pain to have to repeatedly remove it all from the scope to access the screw that holds the clamp to the ring, shim it and replace it on the rail. The fallback of 3 point rings starts to look ever more suitable..... Andy
  14. A misunderstanding here on my part I thought you were inferring that the shims went between the rings and the OTA hence my concern with a CF tube, I see that is not now the case. Here is picture of the WO CRC rings on the ADM bar mounted on the SCT Homeyer cradle, I don't have one (yet) of the dual bar setup. Andy
  15. Thanks for the feedback, I was looking for pinpoint accuracy but maybe this is unrealistic ? I already use CCD calc to get some idea of object sizes on the CCD FOV for the camera's and scopes. I'm using ADM mounting bars and ADM MDS clamps attached to the rings. There seems little or no adjustment on any of the attachment screws as they are all tight. Given what Jesper says regarding no extra benefit it may be easier to dump the CNC rings and use a set of ADM 3 point rings as I've tried unsuccesfully shimming with card (don't fancy using metal shims as it may damage the CF). ATB, Andy
