Does your 15mm that came with your Tal 65mm lack eye relief and true FOV. Well here is the solution.

This is an amazing enhancement for the Tal-65. Here are the magnifications you will get with your  26mm and tube set.

26mm alone    = 19x  Lowest practical mag.

26mm with Tal barlow  = 67x

26mm with Tal provided barlow and tube = 91x

26mm with barlow and Siebert provided Tube #1 =113x

26mm with barlow and Siebert provided tube #2 added= 133x Highest practical mag

(((Combine the two tubes for the highest 133x )))

This eyepiece / tube set package will provide you with all the useful magnifications you might need including 19x and 133x which is your lowest and highest practical magnification. Also it gives you the ER you need to enjoy the scope with or without eyeglasses and you don't sacrifice a decent Apparent field to do it.
