    IC 1318

    FSQ 106 /QHY 367C/E.fric mount 75x3 min IC1318 by Yves, on Flickr
  3. FSQ 106 / QHY 367C / E.fric mount from Gemini Telescope Design 85x3min no guiding / no dithering / No filters used from a severe LP zone M31 E.fric by Yves, on Flickr
  4. Unguided 5 minute shot just above 30 degrees 100% crop, I have never seen this, never for a mount without encoders and in this price range an weight capacity, never .... and gusts of wind in an open field ...
  5. And if you want an adaptor, Andras can quote you on one, I ordered an adaptor for my G53F to fit on the iOptron pier (I can also use my E.fric on it) /Yves
  6. IIt’s straight forward I used no adaptor on my tripod, center M10 bolt and a pin to the north an M8 bolt for polar alignment /Yves
  7. And I did not mention this, but I already had the controller for my G53F so actually I use the same controller for 2 mounts, I just need to reflash the FW .... /Yves
  8. I bought: - the mount and cable for the Onstep from http://www.geminitelescope.com - the Onstep controller from Instein.eu (it seems there where are some health issues with the owner, so better mail for availability) But if you have already a stepper controller it's easy to make it work or buy something more to your liking, or buy all the components and PCB from: https://www.stmbluepillkits.com - I had the counterweights and I have a dozen or so 12v supply's, I think most of us do, - The onstep can be controlled via webpage or android app, no need for a HC - it's also the Philosophy of this mount, reduce waste and complexity, no other mount vendor even considers this. Oh and did I mention it tracks like NO OTHER mount in this price / weight capacity range? I'm sure if you mail Andras he can provide you with all the necessary pieces, but as mentioned it's the philosophy to reuse components you already have. /Yves
  9. The (net) price is EUR 3800 (for EU customers 4636) + controller, I paid 200 euro’s for a ready made Onstep controller, but you can make the controller for 50 euro’s or any stepper driver that delivers more than 1 amp ... /Yves
  10. Last night I got automatic flip + SGP dialed in. The onstep FW needed a setting adjusted, prefer east side. Andras was very helpful and mailed me the same day the adjustment So it’s quite simpel, in the ascom driver you say how many degrees past meridian you can goto, when you are on the west side. With the option in the FW enabled you now can track past meridian and when SGP sends the goto command, Onstep does the right thing and moves the OTA to the preferred East Side ... Another night with 80+ subs unguided and round stars, no need to build complex models etc, what a joy! /Yves
  11. E.Fric: http://www.geminitelescope.com/efric-friction-drive-mount-german-equatorial/ /Yves
  12. Some remarks on the mount: Straight out of camera, No LP filter or Uv/IR filter used, I need to get one, LP correction and stretch, no calibration, no dither, no guiding, 30x3 minute subs E.Fric test by Yves, on Flickr
  13. So I finally had the time to setup the mount in the garden, heavy LP zone, I had no spare LP filters, so in this regard it's just to test the mount, what can I say. E.fric: http://www.geminitelescope.com/efric-friction-drive-mount-german-equatorial/ - It's a beauty, I really like steam punk - Easy to balance, the benefit of friction drive but has clutches so it can move freely. - Easy to polar align, it has a built in adaptor for the Polemaster, so alignment was done in 5 minutes - I use the Onstep controller from Instein - I use geoptic Hercules tripod - I put an FSQ 106 + QHY367C on it, no guide scope! - It slews smooth, low noise level, no noise when tracking - So after the polar alignment I took a 30 sec shot, round stars, 60 second, round stars, 120 sec, round stars, 180 second round stars ... at 1.8 Arcsec/pixel not bad at all ... I still need to dial in my limits for auto meridian flip in SGP ... stay tuned. In my opinion there is NO better mount in this weight / accuracy / performance / price ratio /Yves No guiding, 1 plate solve object dead center, no calibration, no dither (SGP direct mount was to big in jumps) ... 30x3minutes sub E.Fric test by Yves, on Flickr
