Back in  2019, I started a similar thread for the FOA-60. It came, it went, a TAK FS-102NSV is in the house but I still yearn for something smaller. I did have a lovely FC-76DC with 2" FTF upgrade which I sold because I was a fool (stupidly good optics), so I am getting the itch again. The FC-76 DS will be my FS-102's smaller brother or sister (naming takes place after scope is in the house!).

 

Thinking of:

 

- Takahashi FC-76DS

- Baader M54 Clicklock (just as an idea - is the 2" visual back ok? Is it non-marring?)

- 2.5" FTF Micropinion upgrade to focuser

- Either Tak 95mm tube holder or More Blue 95mm diameter rings. Thoughts?

- Losmandy 7" dovetail or Farpoint Losmandy dovetail for Takahashi (depends on Tak tube holder Vs More Blue rings)

 

This will ride on a Gitzo Series 5 and a Diskmounts DM-4.

 

----------------------

 

So, copying from the other thread exactly the words I posted:

 

So, after a few months of ownership (and hopefully of use!) how do you find the scope? What mount / tripod combos? What eyepieces do you use? What kind of objects do you do you find it suited for? Pros / cons? Tweaks / customizations?

 

- Inquiring minds want to know! Also, said inquiring minds love photos and poring over details, so have at it!

If I recall correctly the FC76 DCU and FC76 DS have exactly the same optics.

 

But the DCU is more compact and has a split tube which allows using the dedicated 1.7x extender which also greatly improves color correction from already excellent to insanely good. I always use the extender with my DCU. For some time the DCU + extender has been my primary quick and light-weight grab and go scope for moon, planetary and double stars. I have found that it rides very well on a Vixen Porta II or a Scopetech Zero mount with the Vixen HAL 130 tripod. The only real niggle about the FC76 DCU + Extender combo is that the back-focus is changed by the extender, so reaching focus with the limited focus travel on the DCU's stock focuser required quite a bit of trial and error for me until I found a satisfactory solution. I doubt you will have any such problems with the DS model.

I do realize that the DCU is lighter and has more flexibility, but heart is set firmly on the DS variant!

 

For moon and planets, I have a Zeiss binoviewer, OCS and necessary eyepieces. I generally never do mono solar / lunar / planetary.

Also, if anyone could provide the length of the TOA without the 2" extension and 1.25" adapters at the back, it would be most appreciated!

 

Have to ponder on storage and transport options too...

Nick, Your list essentially describes the DS I am using.

 

FC76DStd.jpg

 

My weather has been more than disappointing for the past year so my comments are based on 2 sessions only. Optically, this scope meets my high expectations as derived from previous experience with a 76DCU which I have since semi-permanently converted to ƒ12.75 with the CQ-1.7x extender. Mechanically, the focuser is the same as that provided with the discontinued Sky-90 and is much more flexible/adaptable than that supplied with the DCU. The FT micro-pinion is a treat (if a bit tedious to install) and the More Blue rings and dovetail are more compact than the Takahashi tube holder. I confess to being a devotee of the Baader click-locks in either size. I can also highly recommend the Scopetech Zero mount and Takahashi 1/10 wave diagonal shown. The DS is a bit heavier than the DCU (primarily due to a larger main tube and focuser), but I see this as a small price to pay for the improved focuser and a retractable shield. In my circumstances, the three inch apochromat is desirable and the FC-76 models are nearly ideal.

Craig,

 

Beautiful combo all the way (and I DO have the Scopetech Zero mount in my ever expanding inventory). Your photo is actually being used by Ted Ishikawa in the More Blue 95mm product page images lol.gif lol.gif lol.gif

 

I have the Baader 2" BBHS mirror diagonal, which should pair nicely with the Tak in terms of both looks and performance.

 

Please, can you measure the scope with dewshield retracted to the end of the 2" Clicklock? Also, how do you transport it? What case do you use?

 

----------

 

My only beef with this scope is the silver anodised part the dew shield is screwed on. I wish it was cream white like the rest of the scope and like my FS-102 NSV - a more "classic" look to my eyes.

Nick, The scope is 18.5" with a 2" Baader click-lock and the shield/focuser retracted. I'm using this case:

https://www.stellarv...5mm-refractors/

... which provides some space for a small finder and diagonal. The SV "soft" cases are the best I have found for my purposes. All of my Takahashi scopes are stored/transported in similar SV cases.

 

Ted Ishikawa is one of the "good guys". He is more than welcome to use my photos.

 

... and yes, the 2' BBHS diagonal is also an excellent choice (for any instrument).

Craig,

 

Ted is a good guy indeed :)

 

Thanks for the measurements and the Stellarvue link - I would go for the C018 as it will (barely) accept the scope with the Baader diagonal attached, and I can play with other dividers I have to fit the compartments to hold the eyepieces and filters I use. Had 3 Stellarvue scopes in the past - how could I forget the convenience of the SV cases is beyond me!

 

It should also (barely) fit in this one which I have - with half an inch to spare, if I want to just move the scope about without anything else.

 

Question: With the Takahashi diagonal and any 2" eyepiece, how far do you have to rack out to focus?

I admit, I don't use that many 2" oculars. The images I post are usually at infinity focus with the eyepieces shown. Incidentally, I've edited my previous post.

Considering the 1.25" to 2" adapter, probably the scope focuses more or less close to where it is shown in your image. Which means that with the ring (or rings depending on Tak Vs More Blue) fully set at the back, it should balance greatly with my Nagler 31mm laugh.gif

I suspect you are right here. I'm always cautious with these heavy eyepieces. I recently acquired a 21mm Ethos (slightly heavier than the 31mmT6) but have yet to try it with the FC-76DS. The position of the rings relative to the center of balance on the OTA is also important. A large AFoV comes with some penalty.

True, but the Ethos 21mm / Nagler 31mm give a massive FOV! Do post when you give it a try!

+1  Another fan of the SV "soft" cases for my Taks.

Markus,

 

Probably Takahashi switched to the silver piece at the end of the dew shield when they also changed the color of the focuser to more blue-ish (from green).

Legit answer! 

 

So, I decided to go with the Tak tube holder to keep the original looks. Ordered the tube holder, the clicklock, a couple of finderbases, a Farpoint dovetail and a small case for it and now hunting for the FTF 2.5" micropinion. Going slowly about it as I am at the same time clearing my cupboards of various gear :)

At the moment, still working on accessories. I have the Starlight Instruments finderstalk with the Baader Surfer V on my FS-102, but that is overkill for the FC-76.

 

Therefore, I am working on a 3D file to 3D print something similar, but obviously much lighter since it will be made of plastic as opposed to metal, and planning to fit the Baader Surfer III  on it.

 

I like the fact that it is slanted, thereby giving more distance between eye and RDF to make it easier to see the RDF dot, plus the added height makes it easier to see through, since scopes do not come with a chiropractor handy to crack the neck. The Surfer III can be conveniently tuned in the field, with no hex keys or anything else.

I also ordered the Tak finderstalk for the 30mm finderscope, but I will use my RACI since the Japanese think that RACIs are for wimps ( I am a wimp! I like my neck just fine without having to visit a chiropractor!). 

 

The FTF micropinion is out of stock for another couple to three months, so I ordered the MEF and once I get the micropinion, I will swap that out. Meanwhile, accessories are coming in. The finderbase on the tube holder will accommodate a More Blue Takahashi-to-Vixen style finderbase adapter, to accomodate the Tak finderstalk and RACI.

 

Farpoint dovetail, 95mm ID Tube Holder, Finderbase, small case (possibly another to be ordered later) and Baader Clicklock already received :)

 

And so it begins!

Very nice Accessoires only the FC76DS is missing grin.gif . I loved my FC76DS bubut had to sold it to buy my FC100DF.  I wished it were a TAK 90 that would fit in the size of the DS . I think you will be very satisfied with your DS when in arrived .
