TAKAHASHI EXTENDER 1.5x FOR EPSILON 130ED
Takahashi
TAKAHASHI EXTENDER 1.5x FOR EPSILON 130ED is backordered and will ship as soon as it is back in stock.
The Takahashi 1.5x Extender for the Epsilon 130ED transforms the Epsilon 130ED into a mid-field 650mm f/5 astrograph. The optical design features 7 lenses in 5 groups, fully correcting the coma across a 44mm image circle, large enough for full-frame sensors.
This extender has been designed with modern small pixel cameras in mind, offering a centre diffraction spot size of 2 microns and 5 microns at the edge of the field. The extender can also be used visually with additional adapters (see the system chart of the Epsilon 130ED).
Note: this extender is designed specifically for the optical formula of the Epsilon 130ED, so cannot be used with any other telescope model.
