Bintel/GSO 2.5x Barlow
Looking for a "shorty" 2x Barlow such as the Orion Shorty Plus or Ultima. (FOUND)
Also looking for a GSO/Bintel 2.5x Barlow 1.25".
Planning to compare them and see which works best in my small refractor.
Please send me a PM if you have one to sell.
EDIT 26/4/2016: Now just looking for a GSO 2.5x Barlow (e.g. Bintel model).
