    Farpoint offered these eyepieces at a competitive price with free shipping. The package arrived in good condition. The items were very well packed. Inspection of product revealed a good quality set of eyepieces. These are well manufactured. There are no cutouts on the barrel, something of a plus for my use.

    I use two of these gems to obtain the widest field of view in my BT100 binocular telescope. With careful focusing the field of view offers pinpoint stars nearly to the edge. Some residual field curvature remains due to the fast f/5.5 BT 100. Contrast is excellent and I was able to tour my dark skies with a 2.8 degree field of view. Nebulae, both bright and dark pop in the large bright field. Object like the North America Nebula fill the field and are amazingly detailed.

    The built-in eyecups can be rolled back if necessary. Eye relief is very good, but I do not wear glasses.

    I am happy with the purchase and Farpoint customer service is easy and quick to deal with.

    Thank you OSI / Farpoint !
