Pentax 125 SDP with dedicated reducer at f 4.9 connected to Finger lakes proline 16803, Takahashi FCT 100 as guide scope using ST 7xe
This shot was "first light" using my Pentax 125 SDP and it's dedicated reducer. This reducer provides an 88mm fully illuminated image circle at F 4.9, extremely fast for a 5 inch refractor...with the incredible 88 mm image circle. Using this reducer, I'm able to obtain a 206 x 206 arc minute field of view...truely astonishing for a 5" refractor
