I bought a pair of the 18mm to use with my Baader binoviwer on the planets and Moon. I have used two ancient pairs of 24 and 16.8 Kson Orthos for years and wanted an intermediate magnification.
Well made, good weight, well blackened and sharp edge to the field all boded well.
Had first light with them on my Askar 103mm triplet. I took the eyepiece wings off as I have astigmatism and they limited the field. Observed Jupitet and the views were excellent, sharp edge to edge, contrasty background, no flaring or unwanted reflections, four/five belts depending on the seeing and a nice shadow transit as well. Very impressive. My Ksons are very good too, but as it was also first light for the telescope I can't say how they compared to the 18mm Baaders as I didnt use them on the night as it was curtailed by cloud.. Very pleased with them, a great bargain at £54 each.

Great lightweight eyepiece that was made for binoviewing. I reckon that the 18mm and the 10mm to be the best of the range. Good clear and sharp images. Great service once again from FLO.

I bought these orthos 10 & 18mm following reviewing various lower priced EP's, I find the EP's very good on the eye and have no issue with their comfort.
Certianly a good lightweight EP and gives good clear viewing compared to some other cheaper lenses mainly plossl's, though that said they compare favourably with my Meade 4000 EP's which I do like .
I did consider buying the Q turret x 4EP's and barlow, howeve they were out of stock.

Excellent service. Thanks

I'd forgotten how sharp a simple orthoscopic eyepiece can be. Compared to my 10mm Vixen Plossl, the belts of Jupiter are much better defined. Only downside is the minimal eye relief, a well known feature of this design.

Excellent service from FLO as usual.Comparing with Kokusai khoki i can't find optical difference.Very bright and sharp,used with ed80,SW10' f4.5 and MAK127.

Have only had chance to use this eyepiece on the moon so far in my 8 inch sct. View was tack sharp and eye relief excellent. Small, lightweight and well engineered. Would recommend

If your scope came with the standard 'super' 10mm and 25mm then you will probably heard plenty of advice telling you to consider replacing the 10mm eyepiece. In my previous scope I did this with a plossl and having recently bought a 10" f/4.7 I decided to give the Baader Classic Ortho 10mm a try. I have not been disappointed. If eye relief and a relatively narrow (compared to some eyepieces costing 4 times as much) filed of view aren't much of a problem I can wholeheartedly recommend one of these.
They represent a big step up in sharpness and contrast over a plossl and a massive jump compared to the stock 10mm supplied with some scopes. You really cannot go wrong with one of these unless you struggle with slightly tight eye relief. Well worth the money even just for the planetary views I have had so far. Jupiter and Saturn are fantastic in this little eyepiece. Get yourself one for planetary observations right now.
