[LVAS] FW: Learning on the forum

All,

 

Re: Cleaning an EP

 

In my haste I left out one very important step...so this is a revised version.

 

Roger

 

 

 
 
All, 
  
I keep all my stuff in a sealed plastic box.
 
100% cotton balls or a roll of surgical cotton, different sizes of washed camel hair brushes, and a blower blub. I keep my camel hair brushes wrapped in saran wrap and I am very careful not to touch the bristles after taking out of the wrapping.  
 
I use the blower bulb first

 

I then use my small camel hair brush, and lightly "flip" it across the eye lens. I do not use any pressure, but attempting to remove any dust particles that may be stuck to the glass.
 
Pull open a cotton ball, taking care to not put your finders on the part for cleaning. Very lose and not waded up. I use a bottle of lens cleaner that I purchased from ES many years ago. It is what they have always have used to clean their optics. 
 
I put a drop on my ripped up cotton ball, and touch and "kinda" lift up on it. I do it again, replacing the cotton each time. I then take a dry piece and lightly dry the eyepiece, not making any circular motion.
 
Finally, I breath on the EP making a fog and do a very light polish.
 
Perfectly clean EP, no damage.
 
If there is an interest by others this would be something good to show for all that do not have a great deal of experience in cleaning EP's. A nice PP presentation showing each step and describing in brief may be good...I don't know.

Roger,
 
I'd like to see that myself as I have an EP with a big old fingerprint on the eye lens.

All,
 
I am so impressed with Fred's idea to present his thoughts and techniques for making a mirror. We could all participate in making these types of presentations to learn.
 
I would like to develop a five slide PowerPoint presentation on my 30+ years of how to properly clean an eyepiece. (proven, and a final examination with a pocket microscope)l 
 
How about another one on, "how to clean a mirror"? I am very thorough, and if you follow these procedures you will not damage the coatings on your EP's or mirror. 
 
There are too may other programs to list.
 
Would anyone be interested in learning...or at least seeing my tried and proven techniques for cleaning mirrors and EP's? 
 
I also clean Maksutov and SC corrector plates.
 
Please respond if you would be interested?????
