has any one tried these and are they any goog ?

Ascension Ultra Wide Angle Eyepieces.

Well, Opticstar don't usually sell rubbish so I would hazard they will be fine. Looking at them they look very much like the WO Swann eyepieces

You can also buy them as "rigel" eyepieces Rigel Rigel 16mm 1.25"Ultra Wide Angle Eyepiece

So I suspect they are a mass produced item which anyone can brand.

never used one but would suspect with your slow scope they may be OK. speak to the supplier - nice guys.

Yep - I've seen them with numerous brand names including Moonfish, Skywatcher (1 model), Rigel, 1-RPD (USA), etc, etc.

They work fine at F/10 and slower. Faster than that and the edges of the FoV progressively get more distorted.

You can often pick them up very cheaply on the used market but perhaps not at the present time while we are still in the "post Stargazing Live" mania
