hazy spots takahashi Fs102 lensPosted By Raul Lopez |
I think that my takahashi have PINCHED OPTICS. Pinched optics can also cause an aberration in a similar class as astigmatism. If a lens or mirror is too tight in its cell, the optic may get pinched enough to effect the optical figure. If that’s the case, the pinched optics can be spotted as triangular or
trapezoidal stars. It said that it could be from the cell too tight, or it may need longer cool down time
The optics are good, but again not perfect.In the daylight they look great, but at night when I shine a flashlight on the lens I can see some hazy spots in the inside of the lens. What is the problem?
