Thanks a lot, folks...

I had all but talked myself out of "needing" to get the Tak FC-76, and now this thread pops up.

I don't need this torture...wink.gif

You realize takhitis is incurable. The dcu is so cute and lightweight plus with the 1.7 extender it’s a planetary scope. It’s superb optically. If u buy new it’s warranted for five years. The perfect travel scope. The mouse that roared. Able to be packed and taken anywhere.

Plus it’s not that expensive. 😝 You need one !!

Apologies to your partner

Jeff

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

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 forgot to mention Doug the 1.7 extender only works on the dcu variant of the scope.

Ah, got it. Thanks, Jsquared. No, I don’t have this part which makes sense as I don’t have the dcu version. The longest accessory tube I have is maybe 2” long and, no matter where I insert it in the optical train or how many other parts I combine it with, NO focus. So it just sits in the bag. 

 

Appreciate your response and clarification.

Doug

The first time a tried BV with FS 78 on Jupiter was a revolution in my observing.

I have since sold that scope and considering another small Tak like the 76DS. Then there is a used Sky 90II in the classifieds. The FOA 60 looks intriguing. Many to choose from!


So anybody here using a bino with their little tak ? I’ve a maxbright II on order if they ever arrive.

I have owned a Tak 76 DCU for a little over a year and have been very happy with it. Perfect grab-and-go scope on my lightweight mount. Optics are extremely sharp, about perfect to my eye. It is hard to believe that it is only 76mm. I use it with the Tak 1.25" prism diagonal and 1.25" eyepieces to keep the back weight down. Highly recommended!

Bill


Hey Bill I took my dcu out for first light and was only able to reach focus with one eyepiece using 1.25 prism diagonal. What extension tube works with your setup ?

I just use the 1.25" adapter that came with the scope which screws onto the focuser.  No extension tubes were necessary.  All my 1.25" eyepieces from a 24 TV Panoptic, all of the 1.25" Pentax XW's and a 2.5mm Nagler come to focus using the 1.25" Tak prism diagonal.

This happened to me with my DL. Of my 1.25” Delos eyepieces only the 17.3 could come to focus. The 2” extension included with the scope was too long so I got a 35mm Stellarvue extension and now I can use all the eyepieces.

For the first time in a month, I was able to observe with my FC76 DCUQ and observed Orion's Trapezium, the lunar Terminator, the crater Copernicus, Rigel, Castor, Polaris, M42, and Sigma Orionis. Maximum magnification used on Castor, Polaris, Trapezium (A-E), and the Moon was 228X. The views were superb!

Barbie, do you notice an improvement in sharpness and contrast when you attach the Q extender to the scope?
