Herschel Wedge with 152mm 1200 TMB refractor?

I have a BAADER Herschel CC wedge that is normally used with my TV 85 APO refractor. The specs say it can be used with up to a 8" refractor.

I have an Officina Stellare 152mm 1200mm fl refractor that has TMB air spaced triplet APO optics. I have the appropriate ND filters, etc. with the Herschel wedge but wondering if I should use a ERF and/or UVIR filter on the scope in front?

I normally use a Baader CC with my 150 mm f/5 refractor without problems. Inside the wedge there are ND3.0 + ND06 filters. Someone adds a UV/IR cut before or after the wedge, I am not sure it is necessary.

I use my Baader Herschel wedge no problem for hours on my TEC140, no ERFs.

Thanks all for answers. Now all we need is some solar activity.

I tried recently a 2" Baader ceramic solarwedge fitted to a APM180 F/6 for about 30min.

Although the windows gets hot it is fine. You can use it with your 152mm refractor
