Default 20mm Vixen LV OPINIONS?

I see a couple of these being offered on Astromart. Why no takers? I need
something in this range. Recommend or not?
Your opinions are valued

One came with my Vixen 102FL. I found images on the dark side and not very
sharp.(Your mileage may vary)
Hey, I have no use for mine(and it cost me nothing)....would you like to
have it for nothing? E-mail me.

Best regards,
Bill

Probably the main reason it's not too popular is that at 20 mm focal length
you don't really need a special design in order to get ample eye relief.

The selling point of LV is that they have the same eye relief (20 mm)
regardless of focal length.

But the eye relief of a 20 mm Plossl is about 15 mm, which is enough for
most people. Plossl is cheaper and probably a tad sharper.

Also I hear that this one comes with Vixen telescopes. If you get one with
a telescope, and you also have a 25mm Plossl, you'll probably use the
latter.

Thanks....I appreciate the info. I haven't had much luck with Plossls
yet---eye glasses.

Have you ever experienced that immense feeling of relief
upon having narrowly escaped a near-tragedy?


I had one...briefly.

Would that those sellers could say the same.

Perhaps most receive them WITH their Vixen telescopes rather
than via independent transactions.

....too many windows...too many image-softening, contrast-robbing
glass elements.

Also, Vixen's eyepieces comparatively...suck, for the lack of a better
word, as I have their 6mm and 9mm orthoscopics. The University
Optics orthoscopics lay them to waste, literally, within my case.

Then, notice that the lanthanums are the ONLY eyepieces currently
offered by Vixen.

Disclaimer: The same does not necessarily apply to the quality of
their refractors, reflectors, catadioptrics, and/or equatorial/alt-az
mounts.

The Parks 25mm Plossl is, in a word, a keeper!

Alan, if the Vixen orthos are bad (I have never tried them) it would be a
very good move for Vixen to simply discontinue them. I am extremely happy
with my Japanese UO and circle-T orthos. There has simply been no need for
me to look any further.

In my part of the world, the Vixen LVW:s are the only serious alternative
to the venerable Pentax XL:s. They are very different from the LV:s, even
if they all have 20mm ER in common,

Anders H.

Only the longest Plossls (over 25 mm) will work well with glasses.
