1. teleskop bunu ala bilirsin

ozellikleri

Primary lens: Air-spaced achromatic doublet

Focal length: 900mm

Aperture: 80mm (f11)

Magnification with supplied eyepieces:

45x, 90x, 112x, 225x

This is achieved with the following combinations:

20mm = 45x, plus Barlow 90x 8mm = 112x plus Barlow = 225x.

Mounting: German equatorial with dual-axis manual slow motions

2. makina olarak bunu sece bilirsin
