“Its design is that of a traditional astronomical telescope…but its also suitable for watching wildlife. Focusing was with the traditional rack and pinion assembly, which was smooth to use. The lowest power eyepiece (25mm) provided a x16 magnification, which gave an estimated field of view of 2.5 degrees. Stars remained sharp across 75% of the view. With this eyepiece, widefield views were particularly good; open cluster M44 was a delight. These wide views did seem to make the background sky lighter, but we could still make out the brighter Messier objects and even spotted the galaxy NGC 2903 in Leo. At higher magnifications the galaxy group of M65/M66 and NGC 3628 could be seen, and by adding the Barlow lens to the 10mm eyepiece we split Algieba and Castor… Saturn was also clear, with Tian and Rhea visible. Overall score 87%”
