Question: New KOWA spotting scopes in Black?

Dear All,
a few days ago I spotted a link to an US birding fair video. That video showed the new KOWA neoprene protection for the TSN 883/0 but as well depicted a short sequence of spotting scopes in Black colour (rubber armoring?) and Red labelling from KOWA.

Now I cannot find the link anymore.

Is anybody aware of this?
Thanks
Michael

There are some pictures of the (small) black scopes on their instagram page: https://www.instagram.com/kowasportopticsnature/

But no further info?
It looks like a 550, but just in black, not rubber amor.

Thanks a lot

Dear Wedejaz,

thanks a lot.

So, also the TSN 883 is now available in Black colour.

Thanks
Michael

Looks like black rubber armoured version of the 883.

Unfortunately, I cannot turn the picture into a 95-100 mm scope no matter how I try.

Presumably the challenge of growing a Fluorite crystal big enough for a 100 mm lens is the pacing item.
Kowa could easily buy a surplus crystal puller from the semiconductor industry, where 6 inch crystals are considered tiny, so there are surely other technical obstacles too expensive to resolve.

Why black I wonder when the last one that colour was c.50 years ago.....a sort of dark grey/black metal body. Was it TS 1?
Their colours have mainly been shades of green, grey, khaki ish in recent years. Perhaps following Zeiss and Leica in black finished Sports Optics. Cannot see Swarovski following.

Not sure if black is a good idea regarding heating effects with optics.
Maybe the scopes are not large enough to be bothered by colour differences.

My custom scopes were mainly blue or grey.

Large photo lenses are often white.

Years ago I noted serious heating effect problems with black polycarbonate scopes. The image was a mess when sun shined on the scope body, corrected easily by having a white T-shirt over it. That scope was a 100 mm Opticron that had fine image quality otherwise.

Kimmo,

Presumably that was caused by turbulence inside the scope rather than distortion of the scope body, in which case magnesium and aluminium alloy bodies would not be much better than polycarbonate.
I fear that my green 883 would absorb almost as much IR as a black one. I dont like socs but perhaps this is a valid justification for them.

Hi,

I don't think that growing 100mm and above fluorite crystals is a problem - neither does Takahashi (or rather Canon Optron who makes the fluorite elements for them and Kowa):

Although asking for a quote for this one might affect your mental health...

Wood is a good material for astro scopes.
Square tubes probably better.

Not sure how well square wooden bodied Kowa scopes would sell.

As Henry Ford once said something like," You can have it any colour you like as long as it's black", about the Model T.

Up to 400mm is possible, apparently, according to their literature.

Probably the price is driven at least partly by the scappage rate as it seems these crystals are delicate and easily shatter during grinding/polishing.

I have a current Edmund Optics catalogue showing plano-convex calcium fluoride lenses intended for laboratory use. The surface quality is 40-20 and they are available in three diameters, 12,5 mm, 25 mm and 50 mm. The prices are €125, €150 and €395 respectively, somewhat cheaper for larger quantities.

John

Might be, might not - Canon Optron probably won't tell us.

But you can buy an FC100 for two thousand pounds and that has a 100mm doublet objective with a fluorite back element in it - although at f7.4 it's a bit longish to lug around. But it will certainly beat any spotting scope in optical quality.

Hi Michael it's the 125th anniversary version...
Kowa has no official announcement yet. When they arrive I will publish them on Binomania.

Ah, that explains it. Will these become collectors items only or stay the same colour for day to day use.

John,

Back then, both I and Jan Meijerink conducted some further testing with other scopes also, some with metal bodies (Nikon Fieldscope) and some with polycarbonate (Kowa 823) and using a hot water bottle/timer as a repeatable heat source. The metal bodied scopes had significantly less (almost none) image degradation from unsymmetrically applied heat. Whether it is dimensional distortion or turbulence I'm not sure, but since polycarbonate has much lower heat conductivity, when sun shines or a heat pad applies heat to one side of a scope only, there was very obvious temperature difference between the heated and unheated sides, whereas with metal bodied scopes very little.

Nikon made a black rubber armored version of the edIIIa. Usually marketed through the “military supplies” outlets. Never have seen a copy in person.
