"The four points of the compass be logic, knowledge, wisdom, and the unknown. Some do bow in that final direction. Others advance upon it. To bow before the one is to lose sight of the three."
My eyepieces are made from the waste product of exploding stars.

Quote:*scatter around the planet*Splitting hairs here, but if there is scatter that you can see around a planet, it is also there across the disk. It's just that the disk itself is too bright to see the scatter, but it has to be doing something very subtle to the contrast - No?Thanks,-Chuck
Quote:Between a 11mm eyepiece with very good quality glass and a 10mm of equal quality I'd be most surprised if the 10mm wasn't said to be just a bit sharper and provided a tiny bit bigger view.
Quote:Hello All:Have any of you compared the ES 82 degree 11mm eyepiece against the Pentax 10.5mm XW?What I am looking for is comparison of color fidelity, sharpness and contrast.Thanks in advance.Jim Miller/Tulsa, OK

Fact: I like reflectors and big ones. All the refractors I own are either finderscopes, binoculars, or riflescopes.

Quote:In practice, a bright target like a planet causes a reduction in the sensitivity of the retina not only in the small spot occupied by the planet, but also in an area around it. The effect, when viewing, is to make the background near the planet darker while peripheral vision may see a lightening of the background sky farther out in the field. It's an interesting effect. It is a reason why faint moons are hard to see immediately adjacent to a planet, since the reduction in retinal sensitivity will reduce the ability to see a faint moon. I had always wondered why I could see a star of magnitude 17, but had a hard time with a moon of Saturn that was 2-1/2 magnitudes brighter--especially when the background near the planet appeared quite black--until someone pointed out this reduction in retinal sensitivity.
