Hi Col,
I see there is an iStar 5"f5.5 objective for sale here:

I would love it, but I know what my wife would say...
"No More Telescopes!!!!" ;)
All the best,

Unfortunately not Col, but I did find this snippet, which you may have already seen, that did interest me. Not sure it's the one you want it's designated as the 204/6 (8inch f/6???)

There is also a wider field 150 f/5 maybe that's the one you meant, ....

Yes, I've seen this AD ...I'm looking to see if anyone has a completed Scope made by Istar themselves.... f/5.5 or f/6 .. in the 5 or 6 inch Aperture.

Diy 127mm Istar f/8 Perseus.

Col, I bought the other one off Phil months ago to do just that but it's been sitting on my desk ever since. One day it'll happen. A nice hunk of glass. What's been distracting me is the 4" f/11 ED I got recently how's that for an excuse
