Product information

The Starwave ASCENT 130mm F7 EDT APO brings you triplet ED level colour correction, and is a very capable, multipurpose imaging and visual platform. 130mm of aperture is a leap in light grasp and resolution compared to a 4" refractor.

A quality Rack 'n Pinion geared focuser with tri-clamp and 2" to 1.25" adaptor and screws for guide-scope mounting are standard.

For high or low power visual observation, the Starwave 130 EDT APO will give the high contrast views only a refractor can, for a very pleasing experience with high power, or low power wide field eyepieces.

The ASCENT 130 is imaging-ready with the optional  0.8x reducer - a great match for deepsky imaging with your Altair Hypercam. For lunar and planetary imaging, a 2x Barlow lens and GPCAM will show fine detail.

The addition of an Altair Solar Wedge or Baader Solar film filter allows high resolution imaging or visual observation of the surface of our nearest star! For solar fans, the views (and images) with a Daystar Hydrogen Alpha Quark and the Altair D-ERF will show amazing detail on the sun - contact us for more info about optimum setup.
