[quote name="Rainguy" post="10079726" timestamp="1585663323"]

I bought a Tak FC-76D from a fellow CNer last fall. Wonderful refractor, dazzling optics. It came with several tubes and extenders and I assume one of them is the 1.7 extender alluded to in this thread. Forgive my naïveté, but can someone post a photo of the 1.7 extender and tell me what its function is and where it goes in the optical train? I’ve fiddled around with various combinations but with the short drawtube, focus is an issue. Right now I have just the visual back and the diagonal set up and this works fine. But the other bits that came with it remain a mystery.

Anyhow, some info on the 1.7 extender, as per the foregoing, will be much appreciated.

Thanks,
Doug[/quote

Doug you can’t miss the extender. It is large being sized the same as the telescope tube and colored white and being six inches or so long. For a picture just google it. It screws into the middle of your scope tube between the focuser assembly and the objective tube of your scope lengthening the scope significantly and increasing the focal length. In place it markedly improves the optics eliminating false color.

I’m confused. I thought the FOA 60 was the only TAK with an extender that threads between the objective and the focuser. The FC76 extender system on the Tak website shows the Extender Q 1.6x.

You can read the reviews I posted above.
The extender Q 1.7 most certainly threads between the objective and the focuser of the fc76dcu. You are looking at the system for the OTHER fc76.

See the review on the fc76Q posted above by me.

The FC-76 DCU can use the same Extender-Q 1.7x unit as the FS-60. This only works on the DCU model, as it is the only 76 whose tube threads apart. Read the above- linked reviews. The non-DCU 76 Must make do with the 1.6x extender that fits in the focuser.

The FOA-60 extender is different still.

I read a casual note on another thread where the 1.7Q was used AND the 1.6 Q was added with a dcu.

This resulted in a F20 scope. The author unfortunately didn’t comment on how well the setup worked.

Not sure why

What are FC76 owners using for storage and transport cases?

https://www.thinktan...port-essentials

This is the case described in at least one review.


The following case looks promising. It has wheels and more space than the airport essentials and is optimized for international travel

Both cases aren’t cheap but they look like they will last.

I use a duffel bag fitted with foam inserts cut from a mattress topper and this works well for me(I don't travel by air or international travel) for travelling by car to a dark site. It cost me about $25.00 total in materials including the duffel bag. The foam does an excellent job of protecting my FC76 DCUQ during travel.

Mine lives in a Craftright pluck foam case from the local hardware. Alongside the FS60. It doesn't get much more portable than that.

I have a Pelican Air 1525 that is used for my TV 85 and would work for my FC76 with divider modifications. I do not fly with telescopes but travel some with one. I wonder if there is a padded case workable? My FC76 is a DCU version but I would be happier not breaking it down. A good padded case sized right would be be ideal.

While I’m waiting for my 76dcu to arrive, what is everyone using for mounts and tripods their Tak 76’s? I’m planning to use mine a lot in the backyard and also as a grab ‘n go light weight setup. I currently have a Stellarvue M1 on a Bogen 3046 tripod that I plan to use.

I have a Feisol Elite CT-3472 Rapid 4-section carbon fiber tripod and a DSV-M Desert Sky mount setup to use.

I've used mine a few times on a very similar setup (M1 plus medium size Manfrotto tripod) and it worked OK, particularly for low to medium powers. While I also have a dob, I somehow dislike pushing smaller refractors along by the tube. At higher powers, it seems more finicky than nudging the bigger tube of a dob because your hand's movement translates to a greater angular movement of the shorter tube. The FC76 will do high powers right up to its theoretical limits. I've now had a Porta II on a surveyor's tripod and been very happy with that, not just for the greater stability but also the slow motion controls. They make a big difference when using high mags and are the next best thing to a tracking mount.

I use my FC76 DCUQ on a Celestron CG-4 mount with dual axis drives for precise, effortless, high magnification observation of the Moon, planets and close binaries. This combo is a perfect grab and go setup that makes observing a pure joy!!  No heavy counterweight needed.

I was looking into using Borg 7080 rings, but I don't think they are available anymore. If anyone is using rings, which one did you decide on?

You have some other alternatives (remember, 80mm inner diameter rings):

Shane,

 

 Go for the PrimaLuce Labs rings and a plate, Astronomy Plus carries these too, this is your best bet and in the dark you won't notice the ring colour :)
