I have seen references to the fact that Meade Super Plossl Eyepieces are parafocal.
During planetary/lunar viewing I switch eyepieces a lot and I am getting a little tired of
refocusing. It is a distraction.
I have seen some references here that sets of Meade Super Plossls are parafocal.
1st is this true?
2nd if it is not perfectly parafocal that is ok, I can do a little touch up. I just dont want
to do big cranks of the focuser.
The Japanese 5 elements are off the table too expensive for me.
Then there are the Japanese 4, Taiwanese? 4, and Chinese 4.
In my reading Japanese have their barrel stamped Japan.
Taiwanese are yellow lettering no country stamp.
Chinese are white letters.
I think for the biggest bang for my buck I want to get a set of Taiwanese ones.
Are these parafocal?
If I can't find a whole set intact, if I buy different lots of these within the same category, will they be
more or less parafocal?
======= thinking outside of the box =====
Is there another line of good, budget plossls that are parafocal?
I have two televue plossls (8, and 11) that are, but building a whole set would be expensive.
Smart astronomy??? Out of production and some are hard to find.
Orion high light???
And once again if I have to buy piece meal as long as I buy the same category
will they be parafocal if that is a feature to begin with? Or do I have to purchase as a set
to ensure that?
======= out of the box 2 =========
someone will say buy a zoom. While that is good advice I have the celestron
and so far it is not quite as sharp as my fixed focal lengths, and it does
not do well in the upper band of focal lengths due to decreasing AFOV.
I do use it when I am too lazy to bring out the eyepiece case,
or switch eyepieces.
