My little girls "help!"Posted By robert rule |
I have a TEC 140 and I left it out one night getting ready to observe. My 10 year old daughter noticed a speck of dust on the lens and to help daddy she took a tissue spit on it and "cleaned" the speck off the middle of the lens. She was very proud that the speck disappeared and that she had helped a "stunned" daddy! However, it left a streak mark on the center of the lens. It does not seem to have degraded the image at all but I am concerned that "spit" is not quite like dew and might cause long term effects. Any comments? Should I be concerned, should I get it cleaned or use the AP cleaning stuff to clean the lens? Appreciate your help on this.
