We are sorry, the manufacturer does not provide a magnification value for the Solarscope

Normally, readjustment is not necessary. But if you want to do so: There are 6 adjustment screws under the rubber. However, these are secured. You must first carefully warm up the glue with a soldering iron and then operate the adjustment screws. If you do not do this, they tear out.

Yes, that is not a problem. You can simply purchase a standard Network Cable (minimum CAT 6) in e.g. 10 meter length

When you (or anyone else) removed the previous 1 1/4" eyepiece clamp mounted on top of the prism housing, most likely at that occasion the extension adapter from the female 36.4 ("Vixen") thread onto the male T-2 thread inadvertedly got unthreaded as well.

So either you would find that ring at the bottom of the eyepiece clamp that was attached onto the prism housing before, or someone else had removed a previous clamp and did not notice that this "thread-adapter" got removed as well.

You might contact your dealer - or buy that ring separately: https://www.baader-planetarium.com/en/baader-adapter-m36.4--t-2-(t-2-part-03).html

Sorry, we don't know this spotting scope so we can't answer for certain. Focus to infinity should work with the included Spotting Scope Adapter from the Hyperion Zoom. You would have to check the threads of the Spotting Scope to see if the Hyperion Zoom MK IV would fit mechanically, either with the supplied or with additional adapters.
