My Andrews Binoviewer arrived this morning, along with the extra 20mm Superview EP I ordered to match my existing one. I must say I am impressed initially, this $99 Binoviewer is a solid unit and the hinge works smoothly and holds position well. All the glass seems to be multicoated and it is completely sealed end to end so no dust can get in. I did a quick optics check and there is no dust or contamination internally. Put the two 20mm Superviews on and adjusted it for my eye spacing and its painting a very large image spot and both sides are exactly the same size and each merged together perfectly without any alignment issues. I can't wait to try it out - if this cloud ever goes away. I'll start with a test in the 102mm long fl refractor because it has massive focuser travel. I will stick it on my 2" ED barlow as well to check out the 10mm binoview on Jupiter, Mars and Saturn.
Observation report to follow.
