Selling a Televue Eyepiece Converter Lens for NV 67mm ECL-67.0 in new condition. Adapts to a 55mm TV PLossl. $75 shipped CONUS.


from TV website: Tele Vue 67mm Converter for 55mm Plössl

This converts our 55mm Plössl eyepiece to a 67mm focal length and reduces the apparent field of view from 50° to 40° to exactly match the 40° field of the NVD objective. That’s a field increase of 20%! Equally important as seeing the entire field available from the 2" eyepiece format, the larger exit pupil of the 67mm focal length provides more light to be amplified. The 55mm Plössl requires more drawtube out travel than most eyepieces and the 67mm attachment moves the focus out by another 1” (25mm) from nominal. Therefore, we recommend purchase of our 2” Extension Tube (X2C-0008) for your telescope when purchasing this attachment. When using the converted 55mm Plössl on a Paracorr Type-2, use the 'H' setting on the Paracorr (do not use EBX-2120 barrel extender with the 67mm Converted Plössl, as it doesn't have sufficient extension for use with Paracorr).
