Not an obtuse question at all Michael - not many people use these for regular photography
SW stands for the maker ( Skywatcher ) its an astro scope. ST is the model name, 120 is the size of the front elements ( 120mm ) 600 is the focal length

Ah, okay, well, as an ex-active astronomer (not much to see around where I live now), I find myself asking more questions:
What is the optical construction? Doublet? Triplet? APO?
I checked out eBay and they have some Celestron Sky Watcher listings, but nothing as large as a 120mm. Is this an older Celestron? _________________ Michael

Factory collimated air spaced doublet with crayford 2" rack focuser.
Non APO sad to say. You can double the price at least for LD/ED glass,
so thats why mine was cheap. You can buy this model without too
much problem. I got mine in Germany. SW are mostly Europe, but you are more likely to find the sister of this ( Orion ) in the US
It has a CA problem because its non APO. Not in every shot,
but those with high contrast. But i can deal with most of the
CA in Adobe CS4 _________________ Dogs Trust + RSPB member |

Ah, yes. Orion I've heard of. Used to be on their mailing list. Dunno about now, but back then they made about a bazillion different refractor models. Think I'll go check out their website.
I've always thought it was a great idea to use telescopes as long lenses. I had a Celestron 4" (102mm) APO years ago that I used to use for double duty, and it was great, but wherever it went, pretty much so did its equatorial mount as well. The ED/APO scopes cost a fraction of what their lens counterparts go for, so there's that value to be had.
So did you just buy an OTA or the mount too? Orion has the 120 ST for $550 with mount and tripod. $320 for just the OTA. It doesn't have those cool looking aluminum knobs on the focuser, though -- just plastic.
$320 for a 600mm f/5 strikes me as a cracking good deal. Add another $35 for a set of rings, and then machine a plate to bolt them to so it can be tripod mounted and, bang, you've got a great land scope. Of course, like with a mirror you only have the one f-stop, but hey . . . can't have everything. _________________ Michael

Yeah they do make a gazillion models, and it seems you found the equivalant. Not exactly identical, but almost. The price seems right..i paid GBP £240 for mine and like you say, if you can live with its idiosyncracies, there's not much to touch it for the price. Even the weight is an advantage @ 8.5Lbs. I dont know of a DSLR of 600mm FL and wide aperture that weighs so little.
I bought just the OTA, but that came with the barrel rings and red dot finder. I sold the finder for about £20.
The mount bar underneath that attaches to the barrel rings ( the dovetail bar ) i had to buy seperatley for about £12/13 - no need to machine anything up. The bar has mount holes for tripod QR plates. _________________ Dogs Trust + RSPB member

Good to know. I saw a listing for dovetail bars, but I didn't know what they were. I'm pretty sure, however, that the Orion does not come with the rings. And it could be that more recent models have lost the cool aluminum knobs because I did see that more expensive refractor models still had them. Moves to keep the cost down, it looks like, what with the worthlessness of the USD and all. _________________ Michael

Yes cost cutting seems to be everywhere right now. You wouldnt want to be in Greece right now though
Orion are not the only US scope seller though, so if you are really interested in getting the reach for little coin, maybe research further. Astro photography is not my bag at all, and IMO, the only other use a scope has is for birds, so its the only reason i bought one _________________ Dogs Trust + RSPB member |

Thanks for noticing. This was taken with a Vivitar 200/3 Series 1 and the effect is a modest amount of home made HDR using Photoshop. _________________ Regards,
