What happened? Did the OP choose one over the other? I'm going through the same choice, with some other options on another thread. Came across this discussion and wondered where it lead?

I don't know what the OP did, but it lead me to purchase a FC-76 objective kit to transform my fs-60 into a FC-76DCU.
I confirm it is a fantastic little scope ! I tested it this evening on the moon up to 230x and still razor sharp, amazing !! I then went up to 325x and the image was still very nice and precise with enough light.

I was never ever able to do that with my TV76, the image went soft over 180/200x.

So I'm terribly happy with the fc-76 !

A TV85 nearer in length to a FC76 is better IMO. For a short tube, the 76 wins. Goes nicely on a TV telepod.

The FC-76 can be very compact :

And for sure it can also be very long ! laugh.gif

The FC-76 is not in the same segment than the TV85 :

  • FC-76DCU : 1,7kg, 1570€
  • TV85 : 2,8kg, 2500€

Compared to the FC-76DCU, the TV85 will need a sturdier mount and wallet... grin.gifgrin.gif

 

Anyway, I owned my TV76 for several years and loved it ! It was an excellent compromise for astronomy and birding.

Really want a FC100 like that!

Which Gitzo mount head is this? Do you like it for astronomy?

It is this one : https://www.gitzo.co...eries-5-g1570m/

 

I had to invert the handle to put it at the front otherwise it would not be possible to point the zenith.

It is not perfect but it works ! It is robust, but not very convenient for fluid precise movements at high magnification.

I bought an AYO II and don't use it that much anymore. The AYO is far better.

Yea it looks like the premium version of my Manfrotto 410 geared head.  It is suitable for a small solar scope and solar work at around 45x mag.

I’m also looking for a travel scope. Looking at Fc76dcu, stellarvue 80 triplet with 2.5 inch focuser and tv-76.

Tak has limited focus travel. I’ve read somewhere you can replace with 2” focuser. With focal reducer would be cool. But no case and must replace focuser. Anyone know part number for focuser?

Tv-76 looks great but another thread said it sucks on Mars with poor optics for red is this true ? Anyone looked at mars with theirs ?

Stellarvue triplet looks great optically but is heavier. How does it travel ?

Cost seems a wash.

I went through this decision recently and have a TV 76.  My priority was travel and I use it for solar(with a Quark), DSOs, doubles and solar system.  So I wanted a robust build and a sturdy 2” focuser to handle the Quark and heavy eyepieces.  I wanted it to all fit in an under-the-seat backpack for airline travel. I really like the Tak 76 but it is longer and is really designed with 1.25” EPs in mind.  I know you can get the DCU which allows you to take it apart and you can upgrade the focuser, but that did not appeal to me.

 

The TV 76 is a good performer for the planets, given the aperture.  I don’t think any 3” scope is ideal for teasing out the details in planets, and it surprises me that so much discussion goes on about planetary observation with small refractors.

After considering and reading all threads I ordered a tv-76 today. Portability is the issue. I wanted a short scope and grab and go viewing with no assembly required. I’ve a fc100dz and a Tec 140 on order for viewing planets. The short focal length and massive field of view (5 degrees ! ) with my Nagler 31 is really exciting. Can’t wait. I ordered the accessory package. Will pair the delite 18 with my other for binowiewing with larger scopes and Barlow for 9mm. 
 

id like to know more spikey131 about your solar rig. Tell me more.

Well after waiting two weeks and no shipping I called around. I found 1-2 tv-76 but no rings anywhere. Quoted delivery time at least 1-2 months. Canceled my order and found a lightly used 1 yr old fc76dcu with clamshell and baader clicklock to allow 2” diagonal. It’s in the Mail as I speak.

 

in retrospect I think the better optics will be appreciated and I’ll get the 1.7 x extender for f12 performance. 
I’ll be happy. I don’t need extreme ruggedness but portability.
