I had to do this. The cost was about half the cost of a new lens. Then i scratched it again...thus the post that started this thread. I'm just living with it this time....

Your picture does not validate that ID for me. Do you have others?

Knowing the size would be nice, and the depth. Lacking that, I'd say likely a Star Coral, perhaps a smooth Star. Definitely not a sponge...no outlet holes for the water flow. I don't suppose you possibly touched it to see if it was hard or soft?

Need some scale and overall morphology to ID this. Your title is Great Star; is that a question?

"36135 (macro port 45) + 36620 (mini extension ring 20) - Used for Oly 60mm macro." This combo is a little long....65mm total, and you only need 56. You could help yourself by using the 17mm extension ring 36617 rather than the 20mm, but that still only gets you down to 62mm. What you'd lose would be your 14mm wideangle end; the 42mm telephoto end is still fine. Why do you have a 36135 port? I thought that only fit the 30mm macro lens? Do you want more telephoto than 30mm but less than 60?

I haven't got enough hands to manipulate a triple clamp underwater....much less three of them!

How do you know he is feeding on krill? Aren't krill midwater and the melibes are bottom scrapers?

Two things: 1 - I use float arms for the bulk of the additional buoyancy needed, because (a) they dry MUCH faster for traveling home, and (b) they are more convenient than Stix floats for using. 2 - I tune up the needed buoyancy with a couple of Stix floats on the outer arms. Easy to add-on and remove just a couple. This also allows some adjustment for salt/fresh, which is only 3%, hardly enough to worry about so long as you are ballasted slightly negative for salt.

It amazes me, however, that when the media directly quote or link to the primary sources, like CDC or WHO, that the information is suddenly deemed false.

Pure BS, unless you mean it is being ignored and downplayed for political service.

Into Truk from where?

For non-cold water I don't wear mine over my wetsuit, but rather on my arm, and just fold back the wetsuit sleeve so I can see it. I can put the wetsuit on or off without removing the computer; mine is not a D5, but is the same size. I tried the computer on my rig, but was never able to see it as well as on my wrist. And I don't always have the camera...a lot, but not always. I prefer the consistency of always having the computer in the same place.

What's wrong with putting it on your wrist?

Yes, been using the blacks in my two YS-D1s for several years. Have 16, use 2x4 at a time while the others are charging. Can get a day of use of of one set befor changing them, but typially change them when I change the camera battery after two dives.
