I recently purchased the Birds Eye View EP from ATWB. This is the same EP as a bwoptik or 1rpd. I have not had much of a chance to use this EP due to the cloudy weather (and extreme cold the few times it has been clear) but I am very pleased with this EP. This 80 degree EP yields almost a 2 degree field in my 10" F5 dob. This is a tremendous value for the price. I primarily have used this ep to observe comet Machholz the few times it has been clear, but this ep also gave very pleasing views of the double cluster, M36, M37, and M42. The view was not sharp all the way to the edge in my f5, (some astigmatism and field curvature) but to me the views on these objects were very good. Also, the customer service from ATWB was great.
