The trays that we use have two screws

There is a nice looking Isotta OM-1 for sale here

Thanks, I see that it might work but Saga is mostly not communicating right now. Interesting that the Bluewater description talks about 67 mm thread on the port which her port doesn't have. BVA

The head that Lauren showed is actually insert molded and can't be fixed. Dave's connectors will work as will the Inon Bushings or the angled connectors from Howshot. Bill

I have one, but I much prefer the 90 finder. The 180 at least for what I shoot is a bit hard for me to find things with. Bill

It took me a while to get over the lack of a 45 finder but I find (except for Blackwater) the AOI 90 degree finder is fine for macro. Bill

A friend is shooting Subal and has the FP-75/3 port for her 60 mm lens. She wants to add a diopter, but the port has no threads. Is there a push-on/3d printed holder to make that happen? Thanks Bill

If you need a charger ping me. I have one you could get pretty cheaply Bill

My understanding is the FLP-06 is a glass port, not acrylic. BVA

Even the cheap colored Ali express clamps are 1/4 20, not metric Bill

Alex: Are you volunteering?

I think the spirals are the egg cases of the copepod, not the copepod itself. We have video where you can see blood flowing through the parasite when the fish's heart beats. Bill
