Art. –Nr. BA-OR-06
Baader Planetarium Genuine Ortho 6mm
Perfect sharpness over the whole field of view. Especially to the edges better than our Plossl- and Super Plossl eyepieces.
x-axis: distance from optical axis in °, y-axis: resolution in arc minutes
Apparent Field of View:
The apparent field of view is about 41°.
Really good contrast, remarkably better as with our Plossls..
Small pincushion distortion.
Eye relief is very short, as expected. If you do not worry about that, the look into the eyepiece is fine.
The very good quality is described on the main ortho page.
In comparison to the Super Plossl eyepieces on the cheaper side the advantage is better edge sharpness, better contrast and lower sensitivity to reflexes. Its called a fine eyepiece all around, and that is correct.
