AstroSolar Viewers and Film

We are very sorry in this case we cannot give a recommendation because our reducers are designed for SC telescopes. We never tried them with ACF telescopes. Please ask the manufacturer of your telescope which reducer works best.

You could use Baader 1¼" T-2 nosepiece with Safety Kerfs # 2458106 to attach the FlipMirror to any 1.25" eyepiece holder.
But as both the SkyMax and the FlipMirror have got T-2-threads, it would be much sturdier (and often shorter) to simply screw them together.
To change the orientation of the FlipMirror, you can use e.g.
Baader TQC/TCR Heavy duty T-2 Quick Changing System (T-2 part #06A & #07) # 2456322
or
Baader Complete T-2 Changer System (T-2 parts #06 & #07) # 2456321
You could also use a small T-ring like T-2 Locking ring with lever - for MaxBright® II # 2458271 as counter nut to fix the FliMirror in a conveniant orientation on the thread, but we'd recommend this only if you don't need to change the orientation too often. It also depends on the length of the T-thread on your telescope if there is enough place to safely attach both the rind and the FlipMirror.

Sorry, it is correct that we don't have a direct UFC S70 to M63 adapter available and also currently have no plans to add this to our portfolio. If the backfocus gets to long by combination with our M68 to M63, we recommend to contact www.preciseparts.com and ask them if they can make a direct adapter for you. They can contact us if in doubt about the measurements of the S70 dovetail.

Yes it will hold a 5kg tube easily.

Unfortunately this cannot work because the laws of physics do not allow it. Please read here about why the filters got optimized and how to select the right filters for your telescopes: https://www.baader-planetarium.com/en/blog/preshift-and-further-information-concerning-baader-cmos-filters/
