I am dealing with a Skywatcher 150mm ED DX, the deluxe version w 3.4” focuser used on the Esprit line. The shaft at the single speed knob is bent causing cyclical scraping. I put in an email request for help from Skywatcher, apparently no phone to call.

 

What are your experiences? Obviously mail to a depot that does repair, replace the shaft, would be ideal. I hate to think what a new focuser would cost. Anyone? Experiences?

You could ask for a replacement pinion assembly to minimize postage. It's easy to fit or remove, with 4 push/4 pull screws as shown in the picture of an Esprit 80 focuser. You need to carefully adjust the pinion/rack mesh such that the pinion isn't forced against the rack, but also to minimize backlash.

The Skywatcher 150mm ED DX is an awesome refractor with the deluxe package. Hope you get it up and running before the observing season is in full swing.

Good luck!

Update: SW Support is quoting $145 for the pinion block assy (as above, we sent them the photo below).

 

They are still waiting for an answer from the factory in China on delivery. The virus has been mentioned. I am placing an order as soon as they tell me how.

 

I have not received any response to the availability of a complete focuser. I think that means no.

 

aa6ww, yes it is a great scope indeed

Until you get a replacement, try moving the scraping single speed knob away from the housing.  If that doesn't work, maybe remove it altogether and just use the other side until the replacement arrives.

Considering the high quality of the parts $145 seems very reasonable. I assume this is a second hand scope, not a warranty issue?

Shipping damage by fedex non warranty.

 

Support quotes 60-90 days. So I am trying to get ordered.

Removing the single speed knob allows the dual side to work, no scraping, temporary fix

 

I asked about a complete focuser, they demurr, suggesting buy a moonlite.

They really should have some parts in stock in the US. It's worth waiting for the part though - the Esprit focuser is very nice when properly adjusted, better than a Moonlite imho.

 

I asked about buying the Esprit focuser for my base model Evostar 150ed and was told it's not available seperately. Skywatcher also said the tube adapter was a little different between the two models. Fortunately the WO 3.3" R&P fit straight on.
