In that case then a K mount T adaptor on a genuine adaptor should work. As that will give the necessary 55mm back focus.

'Bulb' mode is available if you use a genuine Pentax K-Q adapter, not if a 3rd party adapter is used. The reason is that 'bulb' mode is only available if the lens has a leaf shutter (there is no shutter in the camera itself). The main Q lenses (01, 02, 06 etc) contain a shutter. The genuine Pentax adapter also has a shutter, so the camera believes that any attached K mount lens (and presumably telescope) has a shutter. Non-Pentax K-Q adapters do not have a shutter, so bulb mode is not available with them. Without a shutter in the lens or adapter, the max exposure (via electronic shutter) is 2 sec.Biggest problem will be what is its longest exposure setting or if it has it got a bulb setting?

With a shutter in the lens or adapter, as well as being able to do bulb exposure, non-bulb exposures up to 30 sec can be made both with the physical shutter and electronic shutter. Without a shutter, exposure is necessarily electronic and the maximum exposure is 2 sec, no bulb exposure. That's my reading of the spec, I've never tried an exposure longer than about 1 sec.It's not possible to do any galaxy or deep sky work. Min shutter is 30 to 60 secs.

Great stuff well done reminds a bit of the extreme macro challenge here a few years back.

Unless....
The adaptor that Geoff used has a shutter? The mount I presume is either R or EF mount. If that is so, it maybe possible to do it.
