Help with my motor drive

Recommended Posts

Hi everyone!

I've recently bought a R.A Motor Drive and it's meant to track the object so it stays in the FOV but it seems to make the object move up!

I don't know why?

Please help,

Seems like a sillyquestion but have you definitely got it attached to the RA axis and not the dec axis?

If so, have you got it switched to N (for northern hemisphere)

Yes everything is set right but it goes up no matter how much I change the speed

Another silly question - have you set your latitude and aligned your RA axis to north? 

And what object are you talking about. I've found I can get pretty good tracking with stars and dsos but solar system objects will still drift a little.

Could you post a couple of photos of the drive attached to your mount ?

Yes I've done most of it. I've set my latitude to about 51 degrees (where I live) and I may need a recap on how to align the scope to the north.

And yes of course there's a battery in it, here are some pictures

Thanks

If the star still drifts up, as you have described, with your ra drive switched off, then as mentioned you have a PA error.

      Made a new video, this is a Astro Systeme Austria specific video, which has direct driven servo motors.
      To get them to perform perfectly and be able to track unguided, you have to tune theese motors.

      I made a quick video of how the three different methods is working in the "Autoslew" software to run theese mounts.
      Maybe this method of tuning mount motors is related to other brands which has direct driven mounts? 

      Best regards / Daniel

      Forgive a newbie questions…



      I just (at last) got a Celestron C8 with fork and wedge, but on a Meade tripod. (No telescoping legs) Looks like the Standard Field Tripod BUT missing the center leg brace plate and the Telescoping legs… I think it is a version with 36 Inch fixed legs.
      This is an upgrade to my childhood wanted got as an older adult (sadly) Criterion 6 inch Newtonian.  

      But One of the clock motors does not run, so this is a two part question:



      One where can I get a replacement??


      And or I read that the later models now use a D/C motor, can I get one (or two) to replace my A/C motor (s), especially as I want to use the scope out in the middle of nowhere as I live in Phoenix AZ and I have given up on my Criterion 6 Inch as we can barely see more than a dozen stars on a good night.
      So a 12 drive system would be better that a 112 A/C up convertor.

      I could also use a source for used parts if there is one or more.

      Thanks.

      Hi guys, I have made a video of how to mount a Primalucelab Sesto Senso focus motor on a true 3" Feather Touch 3215 focuser.
      I thought some of you might wonder how to use the extra collar you need to mount the motor on to the bigger versions of the FT focusers, and also how to align the motor shaft.

      Enjoy
