  1. I second the vote for the Avalon M Uno. I image with both a 9.25” Edge and an FSQ85. I have had mine for over five years and it never lets me down. I have taken two hour long subs at a FL 2350 with tight round stars. A joy to own. Derek
  2. Surprised there are no replies on this one. I use a Celestron 9.25” Edge at F10 and F7 and it handles this easily. I know others that image successfully with an 11” Edge. Derek
  3. I suspect you would be more than happy with Avalon. My M Uno has served me well over nearly five years of ownership. It has been essentially maintenance free ( no gears to remesh or grease ), responds superbly to guiding, and has been reliable in every way. I’ve also not had any major issues with wind, though don’t image typically with winds > 10MPH. Derek
  4. Meade made a field derotator some years ago that never took off, because of course it was a sloppy design that never worked well. But the idea is there and if done correctly, by a premium mount company, could permit a full night of uninterupted alt-az imaging. I once thought that commercially available fork mounts could never track/guide as well as a premium GEM. But now I have one in the Avalon. So maybe it just takes a commitment from an innovative company. Derek
  5. British sarcasm is way too subtle for most of us yanks to fully comprehend. Now stop making fun of me ? And Merry Christmas all! Derek
  6. Agreed. But let's say for the sake of argument that such a mount could track and guide as well as a premium GEM of the same price and had an accurate derotator that would allow perfect alignment of subs without sacrificing any of the chip/FOV. And being alt-az it would not require a meridian flip nor accurate polar alignment. Why would anyone not prefer such a mount over a similarly priced GEM? Derek
  7. Very impressive efforts with alt-az mounts. It has renewed my interes in alt-az imaging. But I've not been able to read this entire thread so I apologize if this has already been discussed. Has anyone seen the impressive imaging results with the TTS-160 Panther alt-az mount, both long exposure (I've seen up to twenty minute subs) using an OTA rotator, and very short subs using the low read noise CMOS ASI 1600? Not a cheap mount, but proof that high end imaging is possible with a commercially available alt-az mount. Derek
