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.  

2" & 1.25" Aluminum Eyepiece Adapters for Meade 114mm scopes.

This comes in two sizes.  One for 2" eyepieces and one for 1.25" eyepieces.

The 1.25" replacement upgrade is for the Meade 114 astronomical reflector that normally comes with a 2" tube with the .965" plastic adapter.  This allows you to use 1.25" eyepieces.

10mm and 26mm  $119 (114Adapter10-26)

This replacement adapter allows you to use 2" eyepieces in your Meade 4504 or 114mm scope.   You may also use 1.25" with the optional  1.25" step down adapter.

To understand better. 

If you have a filter that will not fit your eyepieces because it is too big you need adaptor (A). 

If you have eyepieces that your filters fall out of you need Adaptor (B)
