Just wondering what people think of the Bintel / GS 8X50 Finderscopes. I will be getting one of the RA ones later this week. I had been planning to get the 9x50 Orion one because it is slightly bigger and I would think better quality but the stock isn't there and the price differential is large. I'm just wondering how good the standard finders are.
Since there isn't much evidence of changing them to larger or other manufacturers, they must be doing alright.
On other sites people talk of upgrading to 60 and 80mm finders. I can understand moving from a small view 6x30 to 8x50, but is there that much advantage to larger-and-narrower finders? Similarly, Andrews and other places offer the 9x50, meaning it is slightly narrower in the field. Is there much difference, and if so, wouldn't it be a negative?
One other thing I just worked out - To get 8x magnification on a 50mm f.l. scope, you'd need a 6.25mm eyepiece wouldn't you. A 5mm or 6mm eyepiece would tend to be a little small. How is the Eye Relief on this then?
