Quote:The Docters have an unbeatable AFOV of 84 deg, and the best is that is 100% usable, because of the eyepiece dimensions and its long eye relief, most should be able to take it all, and sharp to the edge, no signs of curvature, coma, astigmatism, etc..

Quote:Also, I think I forgot when first reviewing them that the only distortion they have is some pincushion, contained but present. I later read that it was introduced to control the rolling ball effect while panning. I don't Know how it works but it is only present when looking at relatively near objects composed with straight vertical and horizontal lines such as buildings. When those objects are farther then it is not noticeable unless you are looking for it.

Quote: their TFOV is exactly 2.2 degrees. [..]. Considering their 40x magnification, should their Afov be 88 degrees instead of 84?
It was a 20x power, 0.3° field of view telescope, sporting a singlet objective stopped down to 15 mm that profoundly changed our perspective on earth's place in the universe.

Quote:Here is something... Just a few minutos ago I confirmed that their TFOV is exactly 2.2 degrees. I used my skysafari iPhone program to confirm it. It frames exactly to the border Aldebaran and star V993. Considering their 40x magnification, should their Afov be 88 degrees instead of 84?
