Congratulations on this neat OBS.

I have additional elsets for 18187 (and 17369, I suppose), but it takes 
about 10 or 15 minutes per month for me to extract them, so I would prefer 
to do so only if they are actually needed.  If they are actually needed, I 
would be happy to do so.  I'm much better equipped to deal with a crisis 
than a four-year study.

Do you mean "For this payload"?  I'm lost trying to follow your point. 
 
Cheers.

Lady looking thru a telescope, talking to Sidewalk Astronomer John Dobson: 
                "Is this part of a study you are doing?" 
John Dobson:    "No, this is part of a study you are doing." 
 
(If anyone has the exact quotes and circumstances of this exchange, I'd 
love to see them.  I think it might have been in the first episode of "The
Astronomers".)
