Great scope for the money but after getting some hd Zeiss binos I realized how much you lose at first and last light by not having the hd coatings. This is where the hd will rock but since I have the Minox 50 this is also why I'll get the 65.
I may be wrong but I thought the hd coating not only helped correct for ca but also allowed better color correction in less then ideal lighting. HD I don't think is just for digiscoping and I do think it helps with low and bright light conditions for keeping colors true. The better lens just keep the object sharp but do nit improve poor lighting conditions which is why an HD 50mm would allow better viewing in low/bright lighting conditions, the lenses just make for a sharp all around image which the md50 has in the center.
Called tonight and the lady said it came with the eye piece! Hope she's not telling me fibs.
