Interesting turn this topic has taken, this is the reason i was earlier investigating a SN8 OTA the FL is just right for what we need. But I did contact Andrewscomm about the GSO 8" f4 a while back and is well priced for the pocket. I think it was 399 for the OTA.
Maybe we can put in a bulk order Mike delivered to the NOC
