No Richard.

I got the others and if they're any use, I might try a set of those just to see.
The EPs haven't arrived here as yet.

One for myself and one set for N1.

We will compare through different scopes and share the findings!

The EPs arrived yesterday and appear to be tidy and solid. However, right on cue, the short term forecast is (unsurprisingly) rain, snow to 600m and rain so will have to delay the review!

I feel for you , but looking forward to the review , what was the total cost and how many did you get ?
I have a young friend just starting out and I gave him a 32mm silvertop and 15mm cheapy to get started and 3 of these might just be the ticket .

I got 2 sets of 3 Brian, one for me and one set for N1 (Mirko).

They are the yellow top 4, 10 and 23mm 62 aspheric EPs. The body seems to be plastic but that doesn't worry me. The test will be in the C11.

Mirko will test his in different scopes too and we'll see what to avoid or not.

All up, NZ$83 plus $4 postage.

Just spent an hour with these guys, 8" f/6 dob. Just some quick impressions:
23mm: usable on axis and up to 50% out from there to the fuzzy field stop. Beyond that: seagulls. Bad internal reflections past the field stop.

10mm: the best of these three, almost in a different league. Good to about 80% out from centre. Ok - ish beyond that. Sharp field stop. The lightest and smallest of these three.

4mm: Seeing not good enough for details but looks promising on axis but the opposite from 50% on out. Colour rather than coma.

Will add more to this later

The ones I used to have had a better field that a good Plossl but I did not have a 4mm in my Celestron X cell lx (60 deg) to compare to a reasonable eyepiece only a 5 , the 10mm and 25 did not work for me but as mentioned at that price even if one works its ok
These are the yellow top, wonder what the red top will do
By the way I took the 10mm apart one single and one cemented double all glass

Fresh from a dark and stunning session...

I honestly couldn't fault the 23mm or the 10. The 23mm was fantastic in a C11 at f10. Globs excellently defined, M83 was stunning and Jupiter was OK but low down at the time. For $15, get them.

The 10mm didn't give CA or internal reflections, but I used it on fairly dim objects, yet to try on bright stuff like Jupiter etc.

I didn't try the small EP thanks to the 23mm!

a long focal length SCT will hide their optical blemishes...try them again in a f5/f6 scope...they'll be horrible. Still, cheap public eyepieces, you can't really worry too much if a naughty kid ruins them!

What's the point of that then?
I'll use them in the C11 and enjoy great views.

100% if it works for you that is all that counts and they give wider FOV than a plossl

you didn't seem to get my point - the eyepieces have issues, but they are masked by your setup. Just cos you can't see the issues, doesn't mean they aren't there!

Guys, guys,
I never thought for one moment that these $3 eyepieces would be replacements for your TV Plossls or Naglers.....

These looked like viable alternative eyepieces for the novice or for Star Party giveaways.

yup. That's why I also said:
