Re: [ATM] What would you do??

["Jerry" <wa4guu@verizon.net>]

If he wants to make telescope, a first time mirror maker should call it
done. Even for a second or third or later mirror, it would be reasonable to
call it a keeper.

If he wants to learn to make mirrors well, he might choose to work more.
What you describe is well made, but isn't to a reasonable limit of amateur
expectation for the size and f ratio. I recommend learning to do better on
following mirrors. Especially so when the edge is good. 

Some people want to learn it all on mirror number 1.  As long as they are
having fun, that is fine. If they really want the telescope, you have
described a very good mirror. Why not use it? There are more glass blanks to
be made into mirrors.

 hey All!,

OK, here's the scenario;

"John telescopenut", has just finished his first classic "8-inch F/6"
mirror,
and beeing his first scope, he's hopfull, in getting excited about those
first-views!,

so he's posted his results of the "mirror-tests", for youguys approval, and
he anticipates
all your replies!,

Mirror tests results;
8-inch. ROC-96-inches,
5-zone masked readings show a "good figure", with a "dognut" that Uncle
Ingles would be proud of!,
[very-low Ripple, and no signs of astigmatism].
Ronchi-image shows no-turned-edge!, and good-bend in Lines!
he ran his "last readings" thru sixtests, and figureXP, and they showed a
strehl of ".89",
and better than 1/8th+ wavefront,,[stop laughing, its my post]
star-test shows a good round-disk, with some descent-rings!,[average-night
of seeing]
so,
wishing to show the results to youguys!, he posts the results,
the only thing he's not sure-of is "whether he should continue with another
figureing-sesion? [go-for that .99 strehl!], or be content with his
results!??

What would you advise??[and be honest!].

John.
