Just wanted to share with you all that couple of weeks ago I was lucky to get an FC-100N Tak in pristine conditions,  it is an f/10 considered the best in his kind for planetary visual ....

According to the history just 100 were made in Japan and only 5 brought to US on those days 1988-1990....I bet there are more than 5 now but I still feel lucky to have one of this FC in my house.

It came with a beautiful EM-100 mount, it is like a perfect match for this beauty! :)

Hope you all enjoy the images.

Thanks,

Hello FCO_STAR,

 

I have a FC100-N like yours and a EM-100 like.. yours! :-)

I had in the past the FC-100N, a Pentax 105SD, and a Nikon 100ED F12 at the same time and have a lot of time to make comparison. 

The FC-100N is, absolutely, the best 4" refractor in the world, better also of APQ ZEISS I compared.

I sold both Nikon and Pentax and get the Takahahsi 4".

 

The EM-100 is really a nice mount too but the lack of go-to system is an handicap today.

Absolutely gorgeous!

 

In the unlikely event that you ever fall out of love with your new Takquisition, i run a Home for Unloved Takahashi Telescopes, where the telescope will be taken out for regular observing sessions and cherished dearly forever. So far I've had no takers on this kind offer, which must mean that Tak owners love their scopes too much to part with them. Still I can live in hope!

 

Mike :-)

Maybe the new 4" f/9 Tak will end up being reasonably close to the 100N...one can only hope!

Congratulations on the scope, it is a rare and beautiful instrument.  Paolo's review is right on, although I will say the slower triplets like the TMB 100/800 give the scope a run for its money.  Art said there were 10 of these imported to the US, but it is quite rare to see one listed for sale.

 

One thing I noticed was that there was very limited backfocus with the scope and that 1.25" diagonals barely reached focus.  I spent a long time trying to get 2" eyepieces to focus with my scope.  While I cannot guarantee this will work with yours, I will put this here for people who may have these scopes in the future and are able to find an old 2" diagonal for an FSQ.  There is no room for a rotating mechanism, so the diagonal stays fixed in position.  With an alt az mount it is easy to point the diagonal facing up, but with an eq mount you may need to rotate the tube.  There may be a better way to adapt 2" eyepieces but it likely involves replacing the focuser.

 

Why go through all of this trouble?

http://www.cloudynig...na#entry6672876

 

You need the following:

 

PreciseParts: make an adapter from a Tak FS-60C focuser (same as in the FC-100N) to a Genetic Wide T-mount Adapter and put 0 for length (shortest possible).  This should be 7.3mm in length

 

Stellarvue 48mm extension 5mm long:
http://www.stellarvu...tube-5-mm-long/

 

Takahashi 2” mirror diagonal for FSQ-106 (TSD0001 NOT the newer model) - only available used:
http://telescopes.ne...or-fsq-106.html

 

The diagonal has an extension that screws into an M48 opening and allows it to be used in 2” focusers.  Unscrew the extension, and replace it with the 5mm ring.  Then put the PreciseParts adapter onto the end of the focuser – you will need to unscrew the black plastic ring that connects the 1.25” adapter.

On mine, this allowed me to barely reach focus even with a Nagler 31mm.

I owned an original model FC-100 as most here already know. Considering how staggeringly sharp and contrasty THAT was, one can only imagine what the N must be like!

 

Congratulations. If I was into visual in a serious way, I'd chase one down, or re-acquire my old FC-100, but my FSQ-106N satisfies all my needs.

Hi, Derek!

 

You're right… the only real issue with the FC100-N is the short back focus

Normally is impossible to reach the focus vita a 31,8 diagonal using the Takahashi adaptor I have.

In my case I built a special adaptor but using 2" eyepiece is not possible.

Really the scope was born to be used straight trough with Taka Orthos 24,5 mm.

And with this combination (or with other old top level orthos) the performances are really stunning!

Wonderful views also with the Lichtencnecker ORTH 31mm.

Thanks everybody for such a kind comments on my new toy.

I did a quick test couple of nights ago using Saturn as a target ( very low / close to horizon ).

The FC-100N performs as a champ with high magnifications. 

I never saw Saturn so beautiful as I did through this piece of beauty.

I agree that Tak's are fine instruments that delivers the best views for visual observers and the best images for Astrophotography fans. :yay:

Nothing beats a slowish focal ratio fluorite doublet for visual use IME  :bow:

I have to admit the longer focal lengths hold some kind of magic for me too. It isn't just the optics, its also the aesthetics. If I'd have known the cheeky chaps at Takahashi were going to bring a FC 100DL out, I'd probably have found the strength to resist the F7.4 DC, or may be not.

I was able to find a second hand 1.6 Extender Q which was going cheap and which makes my F7.5 into a F11.8, giving me a top power with a 2.5 lanthanum of X474, and the stars are still textbook perfect, with no deterioration of viewing quality. The longer version would have been very nice though!

Congratulations on finding such a beautiful scope/mount combination.......

I am going to wait till they release an FC125 F12 ............. it will come eventually.  

Seems the scope market is like the the cell phone market, they started out huge, then got smaller and smaller but now they are getting bigger with each iteration.

 

Hope you enjoy many clear nights with that beauty!

That's the second offer I've had for my TSA in the last few weeks Lewis. :)

I don't use it much but every time I do it impresses me.

 

Hopefully Takahashi will release another 5" doublet one day.

Put me down for one of those as well please  :lol:  :lol:  :lol: . But keep it at f8. I kind of like the rounded FL of 1,000 mm  :grin:
