WO Megrez II 80 FD / APM 107mm f/6.5 / Mewlon 210 on DM-6 + Berlebach Planet
Quote:The difference is about $1. UO HD is $89.95 + $8.95 shipping, BGO is $99 w/ free shipping lots of places.
Quote:Same eyepiece (even same packaging), different coatings.
Quote:...as well as the possibility that the Baader coatings are different and better blackened inside (still don't know about those).
Quote:I'm using my 12.5 mm BGO with a 2x barlow and the eye relief is just fine in that configuration. Can't go wrong with this.
Quote:...after reading that some people had the UO lettering falling off..
Quote:As a side note, the eyepieces in the table which are shown with an asterisk (*) next to their ranking indicates that these eyepieces had portions or all of the lettering and graphics on the housing silk-screened and/or painted. This of course will mean that over time one can expect the lettering to eventually wear off with repeated use and contact. While I did not think this was sufficient to lessen their build quality rating, I thought it was valuable to note for prospective purchasers of these eyepieces as it may impact a personal preference.
Quote:OP, how is the Baader going to work on your f/5 Dob?I'm in learning-mode, but my research leads me to believe the BGO edge sharpness will deteriorate somewhat with the large aperture.My interest is the 9mm BGO.I am concerned about soft performance in my f/4.7 XT10.
Quote:Would the orthos perform well in a f/5 dob?
Quote:Perhaps the only difference between both versions might just be a lettered word (?)
Quote:The grazing angle colour of the coatings is very different,so it's not just the lettering.
