Astronomy Review Excerpts from "A wide-field imager's dream scope"

Appearance, fit, and finish

Tele Vue has a reputation for producing telescopes as beautiful to look at as they are to look through, and the NP101is is no exception. From the optical tube's pebblegrain, powder-coated ivory finish to the glass-bead-finished, black-anodized focuser, lens cell, and dew shield, the telescope exudes quality.

Illumination and color

The NP101is provided a well-illuminated, uniform field that dropped off by less than 10 percent at the extreme corners.
Because the typical CCD chip detects a wider range of wavelengths than the human eye, deficiencies in color correction are obvious. The usual symptom is blue-bloat, where blue halos surround stars. The NP101is was free of chromatic aberration, as demonstrated by the celestial images accompanying this article.

Visual observing

This telescope offers a side benefit for nonimagers: It's an even-better observing telescope. A large-chip CCD camera with small pixels requires telescope edge-field performance that far exceeds the performance required for visual observation.
The NP101is provided a visual observing experience unmatched by most similarsized telescopes I have used.
