TAL 100mm F/8 refractor

[allcart]

is there such a scope? all info says current TAL's are f/10.

[John]

I saw that advert and wondered the same thing. I've never heard of a TAL 100 F/8. All the ones I've seen were F/10.

[AndyH]

Yes, there's a 100mm F7.5, that's recently been released.

From what I've read, it's been primarily designed & made for (and with the input of) the Russian solar folks.

Interesting but not have thought it was this one. I've replied to the add, so we'll find out.

[AndyH]

Review of the above, in Russian. Stick it through a webpage translator.

The only F8 frac that Tal have ever made & still make, is the 75R(75mm F8).

[John]

Thats a new one to me Andy.

How likely do you think that this ad:

is one of those ?

[allcart]

It seems too cheap, but if it is, then I might be lucky enough to get it. Depends on whether anyone got in before me.

[AndyH]

Unless the person has got it direct from the factory in Novosibirsk, I'd say unlikely. They've not been for sale for long AND if he's selling at £75, that's a ginormous loss he's taking.

Possibly a typo in the UKastroB&S listing ??

Sorry for all the bumff I posted previously, didn't realise the ad was on there.

I'd say, odds on a std 100F10 Tal frac?

Andy.

[AndyH]

Hey, even if it is a 100R or 100RS ota, tis a fine price, depending on condition of course.

But I'd want to see pics, pics, n more pics, before parting with the dosh.

[allcart]

I agree Andy, probably a typo, but worth investigating.

[nightfisher]

will be interesting to see the outcome of this, i spotted the add yesterday, thought it was a typo and should be f10, interestingly there is a TAL 75r on cloudy nights that i really fancied getting but not going through the hassle of buying from the states

[allcart]

Yawn!! no reply yet. Don't you just hate waiting for emails.

[Astro_Baby]

Saw the ad estercay ....its too far to go for me and not sure what I would want it for anyway. I assumed it was a typo and he really want £175

[twotter]

I assumed it was a typo and he really want £175

Same here. Pity there isn't a picture to help.

[allcart]

Maybe its just me, but if I advertise something, I check the view count in the morning and respond to mails. It would become apparent if there was a typo and I would correct it pronto.

[allcart]

Well I am now the dubious owner of a TAL F/8 scope, and probably the only member of the F/8 club.

Yes I got the scope and its white. Not sure what it is really. The owner told me it was used as a white light solar scope display model at Scope & Skies a few years ago. It apparently had a TAL logo sticker on it, but it has been painted over and a stenciled sticker put over the top. It has a 100mm blue coated objective, and the tube is approx 750mm from the front to the end of the tube, not including the single speed 2"/1.25 focuser. No visible markings except for a warning sticker about solar viewing.

I'll take some pics tomorrow and see if they shed any light. Except for the dodgy painted bit on the tube, it appears to be in good nick.

[AndyH]

Excellent !

Has it deep purple/blue coatings? Crayford or Rack & Pinion ?

[twotter]

Sounds interesting. Looking forward to the pics

[Naemeth]

Can't wait to see the pictures, especially if it's got purple coatings .

[nightfisher]

well done, lots of pics and more info please

[Marki]

Congrats! Piccies please . Very interested to see what this is!

[allcart]

Difficult to be sure of the coating under room lights, but it deff seems to have a purplish colour. Here are some pics of the tube and focuser. see what you think. Under the rotten sticker is a bigger round logo/sticker.

[Marki]

Looks like the rack and pinion focusser from the 100R rather than 100RS. Interesting - the purple coating suggests its the earlier model too. Any evidence that its just been cut down from the f10? Andy's previous posts suggest that there are some specific "solar" versions at f8. Is this one of those?

[nightfisher]

I think it could be a home brew scope, the focuser is tal so is the objective cell, maybe some one swapped out the lens and shortened the tube
