Has anyone used either of these on a refractor with their NV gear?

or

I am interested in hearing any feedback on the quality of the view. 

 

Thanks!

Ed,

 

With the 2” GSO, I could not achieve focus in the Boren-Simon or the NewMoon. I recall a comment by VonDragon and / or others on using the Antares 2” reducers which is what I use and both focus ( 0.7x and 0.5x).

 

I still use the Mod3 and PVS7- both C-mount.

My refractor is binoviewer ready, so I have mountains of focuser range. The primary concern is off axis performance. 

 

I have the .73 reducer from the Boren-Simon, and it actually works quite well, but just looking for a little extra speed. 

 

The Long Pern, which I linked above, is both a .6x reducer and a flattener.  Someone in the equipment forum said the GSO was not very sharp off axis and we know if it is not sharp using a regular eyepiece, it will be worse using NV. The Long Pern costs almost 3 times as much but it is probably one of those things where it is worth it. 

Thanks for the data points though. I appreciate it, and hope you are doing well!
