Lovely binos Col,

I used to have a pair of the same Oberwerk 45/100's on a height adjustable stand for comfortable zenith viewing. The views were spectacular and so comnfoprtable to view thru, even for extended periods.

Bumble Bee

Hi Folks,

No they're not some strange pair of binos, although you could try if you have very wide set eyes. I just acquired the 2nd of these 2 lenses. They are a pair of Nikon 400mm f2.8 lenses for my take on the dragonfly array thing (x2 for now), - "Bumble Bee" . for a 400mm f2 ... (equivalent exposure) or 600mm f2.8 equiv. or 800mm f4 equiv. with 1.5x and 2x Teleconverters resp. (Need to test the Image Quality and acquire some more Nikon TCs before going crazy on that (the TC) route).

I now need to find time to make a fixture to hold both lenses on a mount whilst also (possibly/probably) providing a means of optical alignment. I need to rope in my brother for some of his wonderful welding work (Hi Den)

Best
JA

Polarex 6" F15 Photo Equatorial Telescope

Finally got around to assembling my very rare circa 1960 Polarex (Unitron) 6" achromat after a few years in storage in preparation for a ground up restoration. I'm hoping the tube and astrographic camera will fit in my conservatory as the mount alone to the top of the cradle is 2800mm and the tube perhaps a little longer. It seems a pity that the telescope is destined to be for display only as the construction of an observatory is out of the question. The complete set up has a weight clock drive, F4 astrographic camera and Polarex 4" F15 guide scope plus a 2" F10 finder scope and the cast iron base measures 800mm x 600mm. I estimate the overall weight to be around 350kg's.

Steve, as discussed recently, you need to make your conservatory roof roll-off

Thanks for your interest guys, and Lewis, I thought about a roll off roof for about 5 seconds but decided it was over the top at 6m x 5m.

TSA120 and binos

Finally got it all together and am very pleased with the outcome of my latest scope.
It's a TSA 120 on a G11 with Gemini 1. I have recently purchased a pair of Zeiss binos from Denis together with the Baarder T2 prism and because I was so sure that I would have problems coming to focus I also purchased the 1.7 GPC. I am delighted to find that I can come to focus by the use of a 2" TV x2 powermate and the standard Tak 2" 75mm extension piece used for straight through viewing without the need for the GPC, this means the 30mm prisms in the binos will not be restricted by the GPC which only measures 24.5mm diameter.
I have mated the binos with a pair of 8/24 Baarder Mk IV zoom eyepieces so the magnification range is 75 to 225, well within the TSA's capacity.
I spent last night observing Saturn and came in feeling that the not inconsiderable sum of money the binos and eyepieces cost was money well spent.

For some reason I am unable to attach photos but will post anyway.

Great setup David. Sounds a lot like my wish list. Though that dream includes a TOA 130 Cheers Richard.

Colin, yes I was very impressed with Saturn and hoping weather will allow me a scan of the moon tonight even if it is a bit on the full side.
Richard, thanks but I'm not sure I could grapple with a 130.

They look like a great set of bino's David. I've found my Tak "Twin View" bino's about the best I've ever tried so far. I think the TSA-120 is possibly the best all round refractor ever produced by Tak as it excellent for visual and AP. I owned a TOA-130s and a TOA-130NFB but think the TSA-120 is more versatile.

TSA 120 and binos

Thanks for the comment Unipol, I was a little nervous about paying out so much to a guy called Denis but he appears to be highly regarded on Cloudynights so I took a chance and right now I am very pleased I did.
Clearly you take better photographs than I do.

You won't regret your purchase David, the TSA will give exceptional views.
