It’s a FSQ-106EDX4. Till now EDX4 was for foreign specification and now with EDXP has native couplers existing in the EDX4 and released from factory including for Japanese marked. No CW anymore. Same optics.

I made this change in my FSQ three years ago...

Has anyone used the FSQ-106EDX4 with a 2” diagonal and 31 Nagler or 21/17 Ethos?

 

I’m interested to know if it reaches focus, and the diagonal remains clear of the rear element.

Hi Allan. I tried using N31T5 on mine using just CCA-250 and slim M54 to M48 adapter, I couldn't reach few mm inwards with Explore Scientific 2" dielectric diagonal. I'm sure using different adapters and/or diagonal can solve this problem.

Thank you for the information. That’s very helpful. waytogo.gif

Allan, the camera angle adjuster needs to be removed and the short 2" visual back installed to get the scope to focus with a 2" diagonal and the N31T5.

 

Edit: with the Extender 1.6Q (50.8) you have more room to play at expense of the wider TF

Excellent thanks Matt. I’ve always wanted to compare my NP101is with and FSQ. There’s plenty of time to think telescopes during this lockdown.

I've had the same thought as Allan.His was the first NP101 I got to use and loved the flat wide field it presented and have thought about acquiring one since. But I've also wondered about the FSQ106 since it could do double duty as an excellent AP tool as well. That could let me thin the herd some too. Currently have two at 4", one used for visual and one for AP. No need for 3, especially if just one would do.

Does the FSQ make a good visual scope? Do the usual eyepieces reach focus?

I've seen one at Texas nautical repair. It was soooo pretty.

Yes, the FSQ106 is a superb visual scope but you have to be careful with the setup due to the short drawtube travel.

"you have to be careful with the setup due to the short drawtube travel."

 

What do you mean?  In what way would one have to be careful?

 

Thank you.

Thank you.

Selecting diagonals, visual backs and eyepieces..... to  work in with the back focus range available with such a short draw tube travel.

Most importantly, the G4 element of the FSQ quadruplet scope  is rather exposed at the back and care is needed that in changing adapters you don't end up with anything colliding with it,

Bill, it would be great to get together again for another telescope comparison. I think you should step up and get the FSQ and we can plan a reunion.

Yes, but you must remove the camera angle adjuster.  The views are best in the 21 Ethos.  But the 31 works just fine.  If your eyes have astigmatism, you might need a dioptric corrector for the low powers this scope offers.   I have found the FSQ EDX4 to be a superb visual instrument.
