Raptronix,

Did you solve this ??

I just bought an EAF for my Esprit 100, which has the same focusser as your image.

I held off buying the EAF until ZWO declared they had a bracket suitable (the Taka mount), which I bought in good faith, but this just leads to the same issue you have.

It seems it can only be secured with one bolt, which is no good at all.

Have you fixed it ? can you post another image if you have pleased.

Hi Galactique
I did the same as you, and I'm afraid I don't have a different solution. The one screw approach does work and is surprisingly firm for what it is, but its not ideal for sure.

It looks like the focuser on the Esprit has changed and so the Tak bracket no longer fits.
Cheers
Nick

Hi Nick

Thanks for the prompt response.

You confirm the worst, I shall have to go ahead and bodge it up and put the second bracket in 'storage'....

cheers

I installed the EAF onto my Esprit 100 and it works.

But it hangs a little off centre clamped by a single bolt, using the extra (not cheap) Taka bracket, which is not a good fit.

Backlash ?? Lash up, I am sorry to say !!

I don't use the Taka bracket - I use the standard one, screwing (only one screw) right up by the focus 'arm'. It is all straight doing that, but i am not happy with the one small screw approach.

Have you considered mounting the EAF to the dovetail plate? you tube user James Lamb has a video showing how he mounted a Pegasus focuser to the dovetail plate of his ES102. You could use a similar solution for the EAF.
