Quote:I think Yuri would do himself a huge favor if he would post a pictorial guide on TEC's website showing how the TEC optical group is oiled, assembled and mounted in its cell. It might help alleviate some of the superstition about oil-spaced objectives. Regards,Jim

Cleaning a dirty lens
Quote:To add to my post above. I have been thinking about how to fold the Pec pad without getting finger oil on it. I have come up with these 2 ways.1. a. Fold a single sheet of lens paper in half lengthwise, twice. Hold the sheet along its short ends only and do not touch the center. b. Fold the resulting 3/4" wide strip in half by gently poking its center point. 2. I remove the pad holding it from a corner, and then gather the four corners together forming a small "balloon" of pad material.

Quote:Perhaps someone could post a youtube video on how to change the oil or re apply the oil.

“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy. Pilots aim green laser pointers at me. Don Pensack proofreads my CN forum posts.” - The Most Interesting Astronomer in the Universe
