To my amazement , I saw a TINY dot of light almost touching the primary. Not touching , not a figure 8 , but clearly split! I ususlly need my Nagler 12 T4 to split this double (117X). Score 2 for the TMB. > There must be something wrong with your 7-inch TMB APO if it usually needs a power of 117x to cleanly split a wide double of 4 arcseconds, such as Ras Algethi. Please check again and take high-end orthos, but not Naglers. In my 6-inch f/9 Meade ED APO, Ras algethi is cleanly split at 55x and 76x using Kasai Ortho 25mm and Baader Genuine Ortho 18mm (same as UO HD Ortho), respectively.

That says a lot about the quality compaired to the Nagler. Page 1 of 1 | ||||||||
