Eyepiece damaged by chemicals
The attached images are micrographs of the surface of an eyepiece which has been damaged by Aeroguard (or similar) I believe (feel free to correct me or add any other relevant detail Houghy!). The damage is to the coatings on the EP lens. It is evident the chemical(s) have eaten away part of the coating, resulting in glarey haloes around bright objects.
The first two images are at about 50x magnification (the white areas are light reflections within the EP). The remainder are of different sections of the lens surface at about 200x magnification.
The EP is Meade 24mm Series 5000 Ultra Wide Angle EP. Feel free to cry if you like...
