Mod of WO 81 GT and SW 120mm refractor with Lunt 60 H-Alpha

Post by Parag » Wed Dec 10, 2014 12:38 pm

Dear Friends,

I am thinking for last few days the possibility to convert WO81 GT APO (F 5.9) as H-Alpha telescope and if possible Sky Watcher 120 mm (F8.0) Black Diamond refractor also.

I am using Lunt LS60Tha Double Stacked telescope. It is pressure tuned and also tilt tuned as second Etalon filter. The blocking filter is B1200 diagonal.


Is it possible? Looking for advise.


Thank you

Please, use white color for text, not purple or ultraviolet. The colors you choose are not readable.
