Curiosity got to me.I see the prism with 4 retaining screws around the prism holder rim base so I guess these are adjusted to accomplish collimation or else they are just holding it there as how would they tilt it?Seems I will need to remove the leatherette grip to get at these but I'll wait to see what Pentax come back with but I now think I could sort this fairly easily myself ( I did it with my Carson 7x18 the other day) although I might need a new leatherette part but maybe that's easy enough got?One way or the other it's gonna get worked on.Disappointed it wasn't just a matter of popping out the prism and rotating it but we live and learn as they say.I'll mull it over in my bubble bath <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" /></blockquote>
