Back of the envelope landed cost at the current exchange rate in $AUD is around $38,200.

If anyone is interested, my AP155 with 4" field flattener and 0.63 reducer and rings is available for the same price :D

There's a point where it would be hard to see the extra performance against several existing high end 150mm. F8 is not enticing either. No reducer offered.

.988 polychromatic strehl though sounds unmatched. I didn't know they were still making scopes I thought they were a company from the past.

According to the link they can make virtually any Focal Length.

E.g. Polychromat 150/840 f5.6 is one option.

That would be better but I imagine the Strehl number suffers.

FSQ130ED got up to about US$14500 or so before it was discontinued so this might be like that if you they supply a flattener.
