Can anyone identify these?

[Watcher]

Got them with a Skywatcher scope I bought used but they're unbranded. I haven't had a chance to test yet but look in good condition. Are they ones that Skywatcher would have supplied or are they something else? The 28mm one is a 2".

[Cornelius Varley]

Skywatcher usually supply 1x 25mm and 1x 10mm eyepiece.

The 9mm bears a resemblance to a Celestron Omni plossl EP perhaps. Not sure about the 28mm. Hard to know for sure.

The 2" fit 28mm looks like the Skywatcher 28mm LER eyepiece that we have. It works very well indeed on our 16" F10 SCT and visitors find it easy to use.

The 28mm 2" eyepiece is a 3 element design rather like a kellner. The 9mm is from Skywatchers earlier LER (Long Eye Relief) range. They used to be on special offer for a set if bought when you bought a Skywatcher scope.

Both eyepieces quite good in slow scopes but both show quite a bit of edge distortion (as you would expect for their cost) when used in scopes faster than around F/8. Certainly good to get up and running with any scope.

The SW Maksutov I recently bought came with just the 28mm 2" LER. I was rather surprised at the quality of the image they gave me. Hunting about for information on these, I concur with John when he says it's Kellner-type design. I like the eyecup on mine as it is adjustable in height.
