The sun was low in our backyard. I placed a flower vase on the table, sprinkled the flowers with water, and used two LED spotlight to highlight this backlight scene.
I took this shot with a Wollensak 3" 1:0.9X Oscillo Raptar 75mm f/1.9 lens. This is a vintage lens from the 1950th, used in a contraption to take photos of oscilloscopes. It produces a distinct swirly bokeh. See photos of the 3D-printed adapter on the Quality HDR Photography Facebook page at bit.ly/3ptIC73. This is a heavily cropped version, followed by enlarging it with Topaz Gigapixel AI to 51.5 megapixels. Gigapixel AI does a very good job reconstructing details using a model trained by millions of photos.
I processed a balanced, a paintery, and a photographic HDR photo from three RAW exposures, blended them selectively, and carefully adjusted the color balance and curves. I welcome and appreciate constructive comments.

We got an interesting flower pot at the farmer's market in Saratoga, California. It looks like the flower pot is on fire with the lotus berthelotii, also called parrot's beak, and lotus vine flower.

Yet another flower bokeh with Wollensack Oscillo-Anastigmat 75mm f1.9. CLoudy day giveth smooth bokeh.
1968
It was the first Marantz receiver in 1968. A solid state construction fitted with a small oscilloscope tube for FM tuning and monitoring of audio signals. 1% Resistors Used - The best resistors available, they give supremely low noise. They are used throughout the receiver in all vital circuits. Massive Heat Sinks - These dissipate heat from the power transistor circuits, and that means longer years of use. My Eighteen makes a perfect sound after 55 years. More is not possible.
A couple of photos, kind of forgotten in the drawer that merits to be printed and shared.
This one is taken with Wollensak Oscillo-Anastigmat 75mm f1.9 lens. This is one of the few Wollensak lenses put on Oscilloscope cameras. They are easy to adapt and use and they all have excellent IQ. They are well known and tend to be expensive.
Even thou it is possible to use it as all purpose lens, and I did that for a while this summer, this lens excel at close-up and details range. Tiny DoF, excellent sharpness, 15 lames in aperture that allows for smooth bokeh even when closed up a little bit, give,IMHO, very artsy, creamy and yet sharp where is needed, images.
This on I took at the garden of my Croatian home.
Any guess what this out of focus object is?
I took this shot with my new toy, a Wollensak 3" 1:0.9X Oscillo Raptar 75mm f/1.9 lens. This is a vintage large format lens from the 1950th, used in a contraption to take photos of oscilloscopes. It produces a distinct swirly bokeh.

Hawlett Packard oscilloscope lens. Optically it seems to be same or very similar to a Wollensak Ocillo-Raptar 75mm f1.9 lens. It is not as sharp as Oscillo-Anastigmat and bokeh is more bubbles one. No traces of swirl.

It's the rainy season in the Silicon Valley, California. I took some shots of carnations and roses in the backyard with a Wollensak 3" 1:0.9X Oscillo Raptar 75mm f/1.9 lens. This is a large format vintage lens from the 1950th, used in a contraption to take photos of oscilloscopes.

I've read that the CU in the name of this Mamiya-Sekor CU 65 mm F 5.6 lens stands for "close up", so this might actually be a regular medium format macro lens. However my specific sample came in a so-called Oscillograph - a camera to capture images of oscilloscope screens. A lot of other lenses used for this purpose are significantly faster than this one, but for some reason it's a lens I like very much.
As you would suspect from Mamiya it is a pretty good lens for what it was designed for: close-ups and macros, And the 65 mm focal length is quite a nice and versatile one as well.
As usual I invite you to take a look at the album to get an impression of what I used this lens for.
Shot with a Carl Zeiss "Sonnar 50 mm F 1.5" (Burke & James mount) lens on a Canon EOS R5.
I was looking for Wollensak oscillo lens for a while. Anyone that fits in my budget as they are now quite expensive.
Oscillo-Anastigmat 75mm f1.9 is one I settled on and first impressions are ...
A further strange discovery when I zoomed-in during processing (see previous original shot): I thought Tektronix were making oscilloscopes? Didn't know they were into cycling?..
This wonderfully crazy lens was originally designed for imaging of oscilloscope displays. It can very well be misused on a camera. Wide open it's got strong character bokeh, is pretty soft (but charming). Stopped down it becomes quite a bit sharper and the bokeh becomes very soft. This is a shot, that I stopped down a little (I don't know how much, maybe about f/4).
The Synchro Alphax Shutter has a T setting, meaning that the aperture stays open (until closed manually). So I can easily use the lens without messing with it.

Macro Mondays theme #measurement. Macro Mondays
The visible size is about 70mm the red ring's radius is about 60mm.
A macro of part of a Hornady Concentricity Gauge. This device is used to identify and eliminate bullet runout (or wobble) to the cartridge case after seating a bullet. Basically it will improve on accuracy when the cartridge is fired in a rifle.
For the Macro Monday measurement theme I also considered a gun powder magnetically damped scale but then it was taken already then considered an oscilloscope, but did not have a signal readily available at the moment. Others I considered was a water level a gun powder dispenser and a cellphone.
Using the Nikon Nikkor AF-P 18-55mm f/3.5-5.6 G VR DX (kit) lens.
Photo taken at Randfontein in South Africa.

Explosión solar desde Eliassen Rorbuer en la última noche de nuestro viaje a las noruegas islas Lofoten. Con este mismo encuadre realicé un pequeño timelapsse de 70 fotogramas.
Podeis ver el video clip que grabamos en Lofoten en el que aparecen 6 pequeños time lapses youtu.be/O32BoA69IeI Es muy divertido :-)

More flower bokeh with Hewlett Packard 75mm f1.9 oscilloscope lens. With no sunshine and pointy light sources it gives this smooth watercolourish bokeh. Wide open is too soft and glowy so it needs to be closed at least a little bit. Fifteen blades help.
Oscilloscope camera lens branded Hewlett Pakard 75mm f1.9. seems to be a close relativ of Wollensack Oscillo-Raptar (if not just a rebranded version of the same lens design).
Central sharpness is good enough when focus is nailed. But bokeh is wildly beautifull.
A Different Kind of Wave
My contribution to this month's challenge of Five on the fifth, the theme was chosen by Margaret, it was "waves".
Another lens with multiples identities bokeh wise. Those are two exemples of difficult background to render with grace.

Those indoor daffodils again, with the backward mounted Elgeet lens!
Mounted an Elgeet 3inch f/1.9 Oscilloscope lens (one of the two lenses in the assembly, probably from the '60s), backwards taped to a bellows mounted to my Nikon FF DSLR, to fiddle with bokeh and optical imperfections. There is but one aperture, wide open.
