With such a fast telescope, you should always use a coma corrector like the MPCC #2458403: Visual Version (V-1 Set), then they work fine.
The eyepieces do not correct coma and would show the coma produced by the teelscope.

Which side goes into the telescope and which goes into the solar filter? I assume the side with the small lens needs to face the telescope, and the side with the large lens should face the H-alpha filter / camera. Is that right? I find that counter-intuitive, because the cone of light should be wider on the telescope side, is that not so?
Its very easy: There is the name of the item written on it. When you are behind the telescope, were the camera/eyepiece is, you must be able to read the text (text is not upside down) Means the big lens points to the filter/camera/eyepiece, the smaller one to the telescope

I have a Celestron Regal 100 ED spotting scope. If I upgrade the supplied zoom eyepiece to the Hyperion can I expect any improvement in the clarity of the image. I find the focus a little 'soft' above 50x.
Maybe... The Hyperion Zoom is designed to work at high magnifications at the telescope. But the eyepiece which is included with the Regal spotting scopes usually isn't that bad, either, and the prisms inside most spotting scopes are designed to work for terrestrial magnifications, as they are seldom used at higher powers than 60-80x.
So, we can only guess if the weak point in the chain is the eyepiece or the spotting scope. The image will not get worse by using the Hyperion Zoom, but we can't guarantee if it will improve.

I would like to experiment ep projection with my Morpheus eps and an APS-C Mirrorless camera with T2 adapter mounted on the camera flange. Is the recommended extension tube still 30mm, even if the Mirrorless camera backfocus is 17,7mm instead of the 44-46,5mm of a typical DSLR? Or is it lower (15mm, even less?) I am wondering if I should buy just the M43-T2 adapter or also the extension tube. And a 7.5mm M43 extension is already provided with Morpheus EPs
The 30mm extension for APS-C is calculated for a DSLR with an additional backfocus of 55mm incl. T-2-adapter. You get this distance with T-Rings which provide the standard T-2-distance of 55mm which is required by old camera lenses with T-thread.
Our MFT-T-ring provides both: The standard distance of 55mm, or a shorter adaptation when you remove the extension.
For an APS-C, you should have approximately 55+30=85mm between the T-thread at the eyepiece and the camera sensor, otherwise there will be distortions or vignetting. This is not an exact distance, but a rule of thumb. With a wide-angle eyepiece, you get get closer to the sensor than e.g. with a Plössl or Ortho.
