TS Optics 2.5 APO barlow - a rebranded what?

[StarSteve]

Does anyone know or recognize what this barlow really is?

I assume it's a rebranded something-or-other like most (all?) of the Teleskop-service branded products.

Ah yes, looks spot on. Thank you.

Hm, but aren't revelations rebranded GSO? I seem to remember having read that.

As far as I am aware, most of the TS branded optics are GSO manufactured.

Sorry to hijack, but are the TS Optics stuff generally seen as being of reasonable quality? I've been looking at a few EP's but couldn't find out anything about the brand so have avoided them up to now.

As has been said, TS don't make anything, they sell re-branded stuff made by GSO and others.

The stuff I've had from TS (mostly via Modern Astronomy) has all been very good - TS 6mm planetary eyepiece, telepack clamp to put a DSLR on the end of my counterweight bar, a 2.5x barlow like this one, DK3 dual axis drives. Possibly other things I've forgotten.

Oh, I should perhaps add that I've been extremely happy with this barlow. I've used it in my little 70mm ED scope (that's another product that TS sell) and for planetary imaging with my C8, as in this shot of Jupiter from November.

Thanks Ludd.

Great shot.

Thanks. And great picture.

Regarding TS quality: I don't have anything optical from them but they are well stocked on all kinds of adaptors and that sort of thing.

Thanks - but i should perhaps add that there's some chromatic aberration showing in this image, and I'm not sure it's atmospheric given than Jupiter was pretty high in the sky that night. I wonder whether the "APO" claim on this barlow is stretching things a bit. Having said that, it was a very affordable (my wife paid for it, he he) upgrade from the basic SW barlow I had before.

I had the Revelation branded version of this barlow for a while and found it pretty good for visual observing. It reminded me of the Celestron Ultima 2x which is a compliment as the latter had great optics.

[StarSteve]

Thanks for the input. Considering the low price it sounds like a good buy then. I noticed (what appear to be) the same one is available from the states branded High Point for only US$50, an even better value.

Put me down as another very happy user of the 2.5x Revelation barlow. All the Jupiter images I've posted in the planetary section this apparition were created using it, as were all my Mars images from its last apparition.
