Binoviewer on Heritage 130P Flextube?

[AlentejoSkies]

Hi,

Is there someone with the experience to let me know how feasible it is to think of hanging a WO binoviwer off a Heritage 130P Flextube?

Please note, I'm a confirmed binoviewing enthusiast. The question is

1) whether the H130 focuser can handle the weight. I'm willing to work on this if it's the only issue.

2) If the two tubes of the UTA were extended 100mm less than fully, and the collimation checked, allowing the BV to reach focus without a barlow, is spherochromatism at f/5 anyway going to spoil the view even at low magnifications?

3) Stretch goal - put the whole thing on an AZ-GTi on a Manfrotto 055?

That would be great, if it works. Or is it only thinkable to someone who has never had this OTA in their hands?
