+RonC Posted September 19, 2020 Share Posted September 19, 2020 (edited) Just finished wiring up and soldering this meter. I have tested it out and was surprised how well it measured amps so tested the scope balance, adjusted it and I will check it out next time I'm guiding!! Outside, next to obsy. and inside.

Bottletopburly Posted September 19, 2020 Share Posted September 19, 2020 (edited) Excellent Ron , it was said in original video to wrap wire around power wire a few turns to make more sensitive reading , will see how you get on 👍 Edited September 19, 2020 by Bottletopburly Link to comment Share on other sites More sharing options...
+RonC Posted September 19, 2020 Author Share Posted September 19, 2020 (edited) Ok, I'll add some induction! 👍 Have you got a link to that video David? Edited September 19, 2020 by RonC added text Link to comment Share on other sites More sharing options...
Clive Posted September 19, 2020 Share Posted September 19, 2020 Looping the wire will only have an effect with a current clamp meter if you loop the supply wire though the clamp a few times. With a standard in-line current meter, there's nothing to loop around. Bottletopburly and +RonC 1 1 Link to comment Share on other sites More sharing options...

+RonC Posted September 22, 2020 Author Share Posted September 22, 2020 Very well David, shows on the guiding graph. I was way off before!! Bottletopburly 1 Link to comment Share on other sites More sharing options...

+TasKiNG Posted September 23, 2020 Share Posted September 23, 2020 (edited) This looks an interesting way of finely balancing a telescope/mount. However I believe that the guy in the video is doing it in the wrong order. He is balancing the RA axis first but should be balancing the DEC axis first. If the DEC axis is not balanced when you balance the RA axis then the RA axis will only be correctly balanced when the DEC and RA angles are in the position that you balanced them. If you then move the RA axis or the Dec axis to different angles it will not be balanced. If you balance the DEC axis before you balance the RA axis then this will not be an issue. Here's an example showing an unbalanced DEC axis with a balanced RA axis ( when horizontal ). As you can see, the RA axis is only balanced in one position due to the unbalanced DEC axis. https://www.dropbox.com/s/vvrgxhypw7ghoru/bakancing.MOV?dl=0 Edited September 23, 2020 by TasKiNG Link to comment Share on other sites More sharing options...

philjay Posted September 25, 2020 Share Posted September 25, 2020 Hmm, I always thought a bit of imbalance is a good thing. My old CGE mk1 mount certainly guided better out of balance. I used to spend ages getting perfect balance only to see a poor phd graph. Then by accident I got the best guiding ever once and found balance was way off. I then deliberately set up with a bit of in balance on both axes after that and all was well. I suppose it,s down to the mounts. +TasKiNG 1 Link to comment Share on other sites More sharing options...
+RonC Posted September 25, 2020 Author Share Posted September 25, 2020 I thought that as well Phil, I'll perhaps experiment a bit and see! Link to comment Share on other sites More sharing options...
Bottletopburly Posted September 26, 2020 Share Posted September 26, 2020 @RonC how did you wire your amp/voltage meter i have same as you three pins positive, neg and output, currently have a voltage only meter so will swap out . Link to comment Share on other sites More sharing options...

Imbalance is good for gear driven mounts as it keeps the gears meshed when being driven, its makes very little difference for belt driven mounts as they have very little backlash ( or should not have 😉 ) Link to comment Share on other sites More sharing options...

Or is it belt driven worms? If so it will still have backlash, albeit reduced compared to the older way SW did it with gearing driving the worm. Thats why I put the belt mod on my HEQ5 to reduce backlash and inprove guiding but it still has the inherent worm backlash. Link to comment Share on other sites More sharing options...
+RonC Posted September 28, 2020 Author Share Posted September 28, 2020 My NEQ6 has a belt drive, installed by Graham. It doesn't 'swing' easily to balance it hence trying out the volt/amp method which so far seems to be working.. Link to comment Share on other sites More sharing options...
