If the phenomenon was localized to a single branch, they might be the eggs of some gastropod. If, on the other hand, it was a generalized phenomenon across various colonies, it could be a gamete release. In the Mediterranean, red gorgonians (Paramuricea clavata) release male and female gametes during the summer. I have witnessed this phenomenon a couple of times, and in the hours preceding the actual release, the fans are covered by these gametes which then detach and float away.

Welcome aboard Jay! We hope you will enjoy the forum. Ciao

It's very long and has a 77mm diameter. A monster and doesn't exist a zoom gear. A Panaleica 8-18 mm is a wiser choice.

Welcome aboard Mort! Ciao

No please, don't go!

Ciao Castillo, Welcome aboard! I am sure you will find all the help you need here.

In that focal range, the Panaleica 8-18 mm is way better but IDK port compatibility.

Hi Marco, Welcome aboard! I saw you are selling your OM kit. What's next? Have you ever tried shooting bw video?

Wow, thanks Would you mind if I move this thread in the DIY section with a proper title?

Yes, I'm a bit in hurry this period. I promised to Romik to add another column. I will do. Keep in account that 99% are 1080p panels that accept 4K input signal.

The last two are really interesting

What's the MFD at 1.4 and 2.4

You made me remember an absurd DUI drysuit. The 30/30. They called it the travel suit for the tropics. It was made of a "breathable" material that they claimed was supposed to eliminate condensation and sweat but prevent water from entering. It didn't have boots but had latex rings at the ankles identical to the wrist seals. Now they don't make it anymore (and rightly so, I say 😁). The suit was not dry at all. I think a friend of mine still has one forgotten in some closet. https://www.diverightinscuba.com/30-30-drysuit.html

Really cool design regardless of its use 😁 What parameters have to be held in account for the fresnel lens? Focal distance... ok but is there a specific distance from the light source?

Thanks a lot!

The record-breaking 2023 marine heatwave has killed nearly all of Florida’s critically endangered Acropora coral colonies, marking the species’ functional extinction in Florida’s Coral Reef, researchers report in Science. The findings sound a dire warning for the future of coral ecosystems in our rapidly warming oceans. https://www.science.org/doi/10.1126/science.adx7825

Did you use a fresnel lens?
