Quote: A fellow in another post mentioned how he thought a 19 Pan was pretty much the equal of his 20mm TV plossl in clarity and contrast. I myself always wrote off the 19 Pan for planets because of it's reportedly high Rectilinear Distortion, but then I realized I would only be using it at F18 and slower. So my question is, at F18 and slower, will Jupiter become distorted at the very edge? Or does the extreme slow focal length negate this effect entirely? I ask because I mostly hand-track with heavily barlowed refractors on alt/az these days, and could really use the extra field.Kirk
