Thanks Rik. The original field of view was about 40 mm on a 50 megapixel sensor. I cropped the image in post to about a 16 mm field of view, The insects wing span is around 8 mm. I attract the insect to fly around flowers using a mercury vapor light which increases the probability of a hit significa...

Excellent work, love the mix of time lapse, real time footage and stills. If the flicker bothers you, you could smooth it out with GBdeflickerApp. http://www.granitebaysoftware.com/Products/ProductGBD.aspx?gclid=Cj0KCQjwu-HoBRD5ARIsAPIPenfIXPg8CCBI6YByQq6FbaPtZ2W3A1r2AfrahjeALT8gI4mXnHyvwzYaAjSJEALw...

Interesting stuff indeed!! I suspect the H2 and O2 can be created with simple electrolysis, or just H2 with pool acid (dilute HCL often called Muratic) and Zinc. Might be electrolysis in soapy water to create the bubble mixtures of H2 and O2. Very cool setup and images!! Best, I'm using a "water to...

Thanks, that's correct. I'm using an 8 inch and 10 inch mirror. The light source is a 500 ns airgap flash and I have a narrow band pass filter on the camera lens.

Hydrogen-oxygen detonations in soap bubbles, video added

Over the last year I've been exploring Schlieren optics. I built a Z-system out of two Newtonian reflecting telescope mirrors. https://www.facebook.com/photo.php?fbid=705986539741502&set=pb.100009904868801.-2207520000.1561592016.&type=3&theater The ability to visualize sound compression waves and ga...

Hi Fan, you are definitely getting there. It's critical to ensure the membrane is at the same tension in all dimension or else the shapes won't be symmetrical. Heat shrink film is the best.
