TS Optics Reducer and Corrector for astrophotography through APO refractor telescopes

? Reduction of the focal length 0.79x - exposure time goes to 62%

? 4-element design for very good field correction

? Easy telescope adaptation with 2" nosepiece

? On the telescope side M48x0,75 female thread for 2" filters

? Additional M54x0.75 male thread for telescope adaptions

? Easy camera adaptation via T2 - M42x0.75

? Perfect definition and field illumination for cameras up to 30 mm sensor size

? Focal Length to 350 mm .... 70 mm
? Focal Length to 420 mm .... 65 mm
? Focal Length 450-500 mm ... 61 mm
? Focal Length 510-600 mm ... 58 mm

? Focal Length from 800 mm .. 55 mm

Picture Shows:
IC 1396 through TS Photoline 60mm with TSRED279 Reducer - Andrew Harrison

First light image from the scope of the relatively faint emission nebula IC1396 is shown left.

This is a total integration of 2 hours (6 x 20 min sub-exposures) which indicates the potential of this scope for capturing extended nebula regions at great depth with speed.

? Field correction: Photoline Reducer TSRED279
? Camera: QSI 583wsg
? Filter: Baader H-Alpha 7nm filter
? Exposure time: 6x 1200 seconds
