I've been trying to get one of these for ages. Finally got one!
Orion Deluxe 1.25" 2x barlow.
This is one of the best 1.25" barlows available for high power. A real sleeper too at just $99!
This and its bigger 2" brother are the only barlows I've seen with internal baffling, and give better contrast on planets than any other barlow I've used, including Televue barlows and powermates. The 1.25" did not disappoint on Jupiter - at least good as the 2" unit.
The internal baffle does present a fairly modest clear aperture, so long focal length EPs will vignette. This is not a barlow for the 24mm Panoptic. But if you are like me and use barlows for high powers only (don't barlow any EPs with F.L. longer than 15mm), this is the barlow to get. Perhaps worth mentioning also that this is a better barlow than the much more popular Orion product, the Shorty Plus. (unless of course you specifically need a short barlow e.g. for reaching focus with a refractor + diag...)
The barrel is nice and long, and like the 2" version, this barlow yields lots of out-focus - would be good for high power binoviewing. The long barrel will also ensure that chromatic and spherical aberrations are not an issue.
The lens coatings are the best I've seen on any barlow. Under overhead halogen lighting they compare favourably with my Televue barlow, with the Orion Deluxe showing darker reflections. (see last two photos - note: same lighting, same camera aperture, exposure and ISO settings.)
