    Default Wide angle eyepieces for ETX 125



    The ETX125 manual talks about the option of using Meade Super Wide Angle and Ultra Wide Angle eyepieces, but when I look at the photos they appear to widen a great deal from the 1.25" base tube. There isn't much room between the eyepiece slot and the body of the scope, so it looks as if they'll be too wide (in the main body of the eyepiece) to slot in. Does anyone have any experience of SWA or UWA lenses in an ETX?
    Many thanks from a very cloudy Isle of Man.....

    Just so happens that Harry Siebert has a "fix" for this right here:
    Siebert Optics - Eyepiece Adapters

    on the right hand side of the above web page-- Then you can use 2 inch eyepieces-- although he claims his 2 inch eyepiece works better. What I have done is use a .5 focal reducer to widen the field and then a 60 degree 1.25 inch 30mm+ eyepiece. This also works but does affect the sharpness of the stars toward the edge of the field of view and also seems to lower contrast a little bit.
