I’ll certainly give you credit for tenacity, but given the on going problems this may be a catalyst for others to look at other affordable solutions. For example the occasional “pre loved” RCOS that comes up for sale. These beautifully engineered and instruments often go for a song compared to their new pricing.
I suspect if you asked Planewave or similar to ship with Zerodur ion-milled optics you’d “need a Bex and a lie down” after hearing the price.
I am puzzled as to why they don’t get snapped up when they appear, but suspect even if the optics are not expensive, the cost of getting a suitable mount puts many off.
As for Orion..I hope that goes well and wait with interest to hear your experiences and results with the new beastie in due course.
