Above ETX 90mm and the Adapter with Self centering holder and and fine focuser on left. On right the simple adapter W/O focus adjustment.

Above 32mm PL 1.25" max field.         Above 2" Siebert 40mm wide field. 

  Try my Observatory class 36mm SWA for the ultimate view the ETX can offer.

Is it advisable to use 2" eyepieces on a Meade ETX scopes?  Is there a benefit?  ETX's have a relatively long focal distance for a small scope and with 1.25" eyepieces cover a relatively small section of the sky.   With the right 2" eyepiece you can at least double the amount of sky you can see.  Sometimes it can come close to triple.  Is this a gain?  The extra apparent field is there, but can't be seen in a 1.25" eyepiece.  A standard 32mm plossl has a maximum apparent field of 52 degs.  With my 32mm Ultra Plus with a 70 deg. apparent field is almost double at 1.8x the amount of sky.   With my 36mm observatory class eyepiece this goes to 75 degs. apparent field, this goes to almost 2.5x the amount of sky.   So this represents a tremendous gain and if you think about it, doubles.   the amount of light you are seeing because you are seeing more of the sky.  This adapter comes with full instructions and is easy to install. The adapter slides over the 1.25" eyepiece socket which increases the internal size because no 1.25" barrel is inserted.  This means that an incredibly low power, wide angle lens can be used with zero vignetting.  Can you image a 40mm with 70 deg. apparent field in your ETX?  Many may have thought that this was impossible, but with this adapter it works perfect and can slew to the zenith with no problem.  Also it does not interfere with the finderscope.. The eyepiece shown in the photograph is my 36mm observatory class.  It has a  75 deg. fov .   This completely changes you low power viewing with the ETX.

This is not for 2" eyepieces since it is the center 1.25" part that focuses

2" & 1.25" Aluminum Replacement Eyepiece Adapters for Meade 114mm or 4.5" Newtonians or Meade DS 90mm refractors and may fit other Meade scopes.

The 2" and 1.25" replacement upgrades are for the Meade scopes that normally come with a 2" tube with the .965" plastic adapter.  This allows you to use 2" and or 1.25" eyepieces.  

1.25" Replacement Adapter only - $19 (114Adapter1.25inch)

2" Replacement Adapter only - $19 (114Adapter2inch)

2" with 1.25" step-down is - $29  (114Adapter2"-1.25")

2" to 1.25" step-down adapter - $10 (SD2-1.25)

If you get one or more eyepieces below with your adaptor you will get the 2" or 1.25" or 2" with 1.25" step-down adaptor for $10 off the regular price. Also Minus $10 for each additional eyepiece. If you have question call or email

EX:  (Performance + 1.25" 13mm $59 +  2" Replacement Adapter $19 = $69

So if you get 2 eyepieces and the $19 adaptor it would be $69 + $49 = $118 total.

----------------------------------

 Performance + 1.25" 13mm  for $59    (114Adapter13)

 Performance + 1.25" 14mm  for $59    (114Adapter14)

 Performance + 1.25" 15mm  for $59    (114Adapter15)

 Performance + 1.25" 17mm  for $59    (114Adapter17)

 Performance + 1.25" 18mm  for $59    (114Adapter18)

The above eyepieces are ideal for use with these type scopes but this $10 discount offer on the adaptors goes with the purchase of any SiebertOptic's eyepieces.

This replacement adapter allows you to use 2" eyepieces in your Meade 4.5" or 114mm scope or a 90mm Meade DS refractor.   You may also use 1.25" with the optional  1.25" step down adapter. 

Is it advisable to use 2" eyepieces on a Meade 114 scope?  Is there a benefit?  With the right 2" eyepiece you can at least double the amount of sky you can see.  Sometimes it can come close to triple.  Is this a gain?  The extra apparent field is there, but can't be seen in a 1.25" eyepiece.  A standard 32mm plossl has a maximum apparent field of 52 degs.   With my 36mm observatory class eyepiece this goes to 70 degs. apparent field, this goes to almost 2.5x the amount of sky.   So this represents a tremendous gain and if you think about it, doubles.   the amount of light you are seeing because you are seeing more of the sky.
