Sky-Watcher 2" Eyepiece Holder for Dobsonians - 57mm
This Sky-Watcher 2" Eyepiece Holder is a spare part that replaces the eyepiece holder supplied with Sky-Watcher Dobsonians that have a 57 mm focuser opening. It securely holds standard 2" eyepieces and accessories.
A Secure 57mm Replacement for Sky-Watcher Dobsonian Focusers
If the original eyepiece holder on your Sky-Watcher Dobsonian is lost or damaged, this holder replaces it. Owners note that older Sky-Watcher Dobsonian drawtubes are slightly larger than 2", so a 2" eyepiece cannot be push-fitted straight into the drawtube; the holder adapts it to accept standard 2" eyepieces.
Choosing the Right Size: 57mm vs. 50mm Eyepiece Holders
Sky-Watcher makes this holder in two sizes, 50 mm and 57 mm, matched to the focuser opening of the Dobsonian, so the correct size depends on the telescope. Check the focuser opening of your Dobsonian before ordering.
-
This 57 mm Holder: Choose this version if your focuser opening measures 57 mm.
-
The 50 mm Holder (SKU SW-DOB-EP-50): Choose this version if your focuser opening is 50 mm.

How do I measure my telescope to see if the Sky-Watcher 57mm holder will fit?
Sky-Watcher sizes this holder by the focuser opening: this one is for a 57 mm opening, and a separate version fits a 50 mm opening. One owner measured the stock Sky-Watcher 2" adapter at 57 mm, or just under, at its widest point, which matches the inside diameter of the receptacle at the end of the drawtube.
Why can't I just put a 2" eyepiece into my Sky-Watcher Dobsonian's focuser?
Owners note that older Sky-Watcher Dobsonian drawtubes are slightly larger than 2", so a 2" eyepiece cannot be push-fitted straight into the drawtube. This holder fits the 57 mm focuser opening and securely holds standard 2" eyepieces.
Will this 57mm holder accept 2" accessories as well as eyepieces?
Yes. Sky-Watcher lists it for 2" eyepieces and accessories.
What's the difference between this 57mm holder and the 50mm version Sky-Watcher offers?
Sky-Watcher makes the holder in two sizes matched to the focuser opening of the Dobsonian: this model fits a 57 mm opening, the other a 50 mm opening. Both hold 2" eyepieces and accessories.
Is this Sky-Watcher 2" eyepiece holder the same one that came with my telescope?
It is a Sky-Watcher spare part that replaces the eyepiece holder supplied with Sky-Watcher Dobsonians that have a 57 mm focuser opening.
