Sorry, forgot to say. Sirius Optics in QLD. $99 + postage new. For the quality of the product it's an absolute bargain. All metal body btw, but still quite light. I don't know of any other place that sells them. Bintel sell the 2" version - I approached them first about the 1.25" but was told they cannot get it so went with the QLDers.

I know a lot of people are going to be skeptical of that statement, so I thought I'd elaborate...
IME you always get some "anomalous" light, scattering and/or reflections (from eyeball or o/wise) in a non-baffled barlow - especially when barlowing complex large FOV EPs - e.g. XW or Nagler T6 in TV barlow or powermate. Not to a great extent (and many people would not think it worth mentioning) but certainly enough to tell one is using a barlow. With a good barlow like eg TV, these can often be eliminated or minimised by readjusting one's head & eye position for best view. But with a dob this has to be done continually as the object (usually planet) moves across the FOV and it gets tiresome and one wishes one could do away with the barlow. The baffled Deluxe barlows are the only exception IME, delivering the highest contrast views of the planets across a dark sky background without any fuss.
