Nexus & Nexus DSC Owners' Thread

Really appreciate your input.

The white disk is definitely being gripped, and isn’t ’rotating’, but the whole unit simply doesn’t stay firmly in either Alt/Az aperture opening of the mount, despite hard tightening. 
I’ll try to upload a video in the next day or two.

As you can see ( hopefully ) despite significant tightening the discs remain loose.

Great videos!

Clearly shows the problem.  Are both axes affected? Are the inserts supplied the same for both axes, I believe they should be different.

[Elara]

Thanks Keith.

Another attempt last night, and by loosening and re-tightening I’ve managed to fix the problem with the Alt Axis. The IFU recommends that you DON’T over tighten and I’m pleased to say that the Alt. encoder disk assembly is without movement, but with some ‘turn’ remaining in the Allen head screw, if needed ( hopefully not!) 

I’ll try a repeat with the Az. later today and let you/others know how I get on.

As far as I can tell each white disk looks to be the same size. Obvs. I was careful not to mix them up during original assembly.

Great service from FLO who emailed and were concerned to see that I get a solution. I haven’t heard back from Serge; I know he’s busy and it may just be me anyway!

Again, appreciate your suggestions and input!

Cheers 👍

A quick update:

Serge called me this morning, the upshot of which is : he is working on a solution! 
I’ll post results as and when, so for those interested, and or with the same mount, bear with me .

I’d add, as a general comment, that I/we are very fortunate to have suppliers/distributors around the world, like Serge, who care that their ‘products’ work as advertised, and that their customers are satisfied!

A further update:

After a few more weeks of waiting I got an email alert to tell me that the new ‘parts’ were on their way. Serge included a special aluminium ‘tool’ (see photos ) for removing the existing inner ring, parting it from the magnetic ‘encoder’ ring. 

This morning, a phone call from Serge…

Using a vice to hold the aluminium tool, with a rubber hammer, I tapped gently on a wooden dowel, to force the inner plastic ring ‘out’, leaving just the magnetic ring, which I then fitted onto the new, wider diameter inner; hey presto, both done and very easily.

The fit was MUCH better and I could sense that there would be absolutely NO play compared to the original ones. I tightened everything up, per instructions, and checked via SETTINGS / ‘TEST’ on the Nexus DSC Pro: both Alt / Az responded accordingly. It’s overcast today, but the Clear Outside app. is predicting a suitable sky on Friday evening/after midnight, into Saturday. I’ll let those interested know how I get on with alignment and eventual use.

Super service from Serge/Astro Devices, so far so good; thanks to FLO  for their interest and offers of help!

 

#1. Aluminium ‘tool’

#2. Showing ‘inner’ pushed through, and magnetic encoder ring removed

Thats good new.

Typical of Serge's excellent support, despite the fact it is he dealing with someone else's product that is made with poor control of tolerances.
