William Optics Binoviewers Super Package


After much Internet research I bought the Williams Optics Binoviewer. It got the most consistent good reviews. At first I was disappointed as it would not get focus on the 10 inch Sky Watcher Flex Dob. Focus was achieved by shortening the telescope by about 9 cm. ( A big bonus on these Flex Dobsonians ! ) After collimating the telescope I was blown away by the almost 3D views of M42, the Tarantula Nebula in LMC and 47 Tucanae Globular Cluster next to SMC. Jupiter was sharp and contrasty but a bit small with the supplied excellent 20 mm Swan eyepieces. I fitted 2x 10 mm eyepieces and watched the red spot moving across the planet. Four bands could be seen with very clear festoons on the two central ones. This Binoviewer will be permanently attached to the Dob except for when I do Astrophotography. I also plan to get 2x matching 5 mm LET eyepieces to get even better views of the planets. You haven't lived until you have looked at the brighter deep sky objects and planets with a large Flex Dob and a Binoviewer. Do yourself a favour and get one, you won't be sorry !!.
