I see these are on promotion right now - anyone have any thoughts on these eyepieces? I am considering grabbing a couple of them.

Promotion? - Most likely 'Dumping', as they have not garnered good reports.

I'm sure there will be others that will chime in that have actually used one, so hold the trigger finger until then.

But WHY are they considered BAD? Someone please explain this?

I've had a few and they performed quite well in a C8Edge. I didn't particularly like the round steel finish thou. The Luminos were supposed to be billed as very flat field too, if I remember right.

I too was considering to get a few also, but now will hold off getting any, "replacements".

More importantly, what other 82 degree WF eyepiece would be a "GOOD" choice, Explore Scientific?

Thank you for any info about these eyepieces.

Have the 10mm, and I do like it. Performs very well in all my scopes.

On a recent trip to the very dark skies of West Virginia, this eyepiece gave very nice views in my 12.5" f/4.8 dob on a variety of DSO objects.

We did compare it to a 10mm Delos a little while back using a 16" f/4 dob and the edge-on galaxy Ngc 891.

The Delos was the better eyepiece, but I consider that line as good as it gets. Still the view of the galaxy with the 10mm Luminos was quite good.

I only tried the 23MM and it had a large ring of fire around any bright object, it also had false stars, so a bright star would appear as 2.

I also had a 23MM Axiom and it was a much better eyepiece, the ring of fire was not visible at night and the I didn't see ghost stars.

19mm Luminos - internal dust and fingerprint. Loose retaining ring. One of the worst cases of edge of field brightening I have seen.

Exactly the same for me. I sold mine and bought a 20mm ES100 and couldn't be happier.

Never looked through one, but if I saw that in an eyepiece it would be the last time I ever used it.
