Altair Starwave 115 F7 ED Triplet Refractor
The Starwave ASCENT 115mm F7 EDT APO brings you triplet ED level colour correction, and is a very capable, multipurpose imaging and visual platform. It offers more light grasp and resolution than a 4" refractor with similar portability.
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 115 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 115 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 a wealth of 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. Needless to say, the views (and images) with a Daystar Hydrogen Alpha Quark and the Altair D-ERF are nothing short of amazing at this aperture.
