1. Overview

The new Morpheus line of eyepieces from Baader Planetarium provide a

Tele Vue has introduced 3 new focal lengths to the Delite Series, see William Paolini's continuation of this review for the 5,9, and 15mm DeLites eypieces .

Tele Vue has just released their much anticipated DeLite series of eyepieces, their first new eyepiece line since the Delos series was launched in 2011. The new DeLites have a 62 degree apparent field of view, a generous 20mm of eye relief, and an adjustable and lockable eyeguard, all features intended to offer viewing comfort and ease of use.

In this review, Bill Paolini, author of the book “Choosing and Using Astronomical Eyepieces", reviews the 7mm, 11mm, and 18.2mm DeLite eyepieces, the first three focal lengths available in the series. Bill puts all three eyepieces through their paces and compares them to other premium eyepiece brands during observations of deep-sky objects, the Moon, and Saturn with a variety of

This conversion kit allows you to easily convert your single speed Crayford focuser on your GSO scope into a precision 1:10 micro dual speed Crayford focuser. If your scope has a reasonably fast focal ratio, say f/7 or lower, the depth of critical focus is extremely shallow and becomes even shorter for very fast focal ratios. Although the single speed Crayford focuser allows you to achieve critical focus for visual applications, it may not be precise enough to achieve perfect pin-point focus for imaging applications. This conversion kit will allow you to greatly extend the functionality of the Crayford focuser unit and enable very precise focusing during imaging as well as for visual use.

Please note that this kit can only be used to convert the newer GSO single speed Crayford focusers which have a small set-screw sitting between the tension adjustment and focus

1. Technical Specifications

- AstroSolar Safety Film is a specially manufactured streak- and blister-free foil only 0.012mm thick.
- The film is manufactured by Baader Planetarium, Germany.
- The base material is not Mylar. The quality of the solar image is immeasurably better than can be achieved by using so-called Mylar "rescue blankets" or similar materials.
- The basic development of this precision film was made in laboratories for nuclear and particle physics. Due to it's absolute homogeneity, the foil attains the optical performance of high quality plane-parallel glass filters.
- High density coatings on both sides of the foil ensure a highly uniform filtering capacity without pinhole effect, resulting in an extremely contrasty
