  1. I use a pair of AE binoviewers which are chinese made and almost identical to the TS ones. The thing to make sure of is that you get a set with the self centering diopters as these make it much easier to keep the EPs centred in the binoviewer. Also worth considering is the length of the light path in the binoviewer and the clear aperture in it. I got a Siebert MultiMag OCA 1b from here http://www.siebertoptics.com/SiebertOptics-OCA.html#Ad 1b which allows me to reach focus in all of my scopes with a 1.25x magnification. I use either Vixen SLV EPs or BST Explorers and the views on planetary and lunar objects are wonderful. For lunar viewing in particular I always use the BVs. I can see the full disk of the Moon with a pair of 18mm BSTs and my Orion Optics VX10L which has a focal length of 1600mm, and, depending on how good the seeing is, for higher powers I use either: a pair of Meade 4000 9.7mm for 206x and a 1.2mm exit pupil a pair of Vixen SLV 9mm for 222x and a 1.1mm exit pupil a pair of BST Explorer 8mm for 250x and a 1.0mm exit pupil I have a pair of Meade 4000 6.4mm EPs as well but I find it difficult to merge the images and the magnification is too high for the seeing at my house anyway most of the time. For high power viewing I probably use the 9mm SLVs the most and the BST 8mm the least. The Siebert MultiMag OCA is better quality than the barlows I have used before I got it and I prefer the lower magnification it delivers although it can also give 2x or 3.5x in different configurations. If I upgrade any part of this it will be to send the BVs off to Harry Siebert to get them supercharged so I can use EPs with a larger clear aperture for wider views. I think the low mag OCA is worth having more than more expensive BVs as it means I can use any scope I like with the BVs as long as the focuser will cope with the weight and the chinese ones like the TS are light. I would recommend reading through Harry Siebert's website. Although the appearance of it is difficult sometimes, the info on there about binoviewing and binoviewers is excellent and helped me no end to choose what I wanted. I hope this helps you with your choice.

  4. Thanks guys, I'm really pleased with it :). These were taken from a room at the Bellagio. Worth it just for the view of the fountains and the strip. We didn't go to any shows, too busy gambling :D.
