Anyone encountering the Danish band Savage Rose or indeed their tiny yet powerful lead singer, Anisette [Koppel] in concert or on disc, will appreciate my immediate associations of these images.
The 50 mm f/0.75 Heligon on a special-modified Nikon 1V1 to bring the lens closer to the film plane. I took these in my back garden very late, after nightfall, and hadn't expected anything special actually. Imagine my surprise when the aphid turned up on one of these pictures.

The second image is impressive. The color fringing caused by the chromatic aberration works amazingly in harmony with the flower and the leaves.
-
By the way, some description of the lens on ebay refers to "yellowing". I wonder if it uses the Thorium glass?
-
Many samples I have seen of the various Heligons over the years are quite brownish tinted, yes. They also frequently show delaminatation or flaws in the internal coatings. Adds to the attraction of these exotic lenses, probably. Sometimes it helps to boil the glass elements. (no joke, Erik has done that ...).

I've heard about a guy who uses a microwave for that. The yellow/brown tint will disappear. But I also heard that the lens element treated in such a way will fog after a while.

First image is very pleasant :)

A very nice capture, that evokes thoughts towards the colours used by the impressionist painters. They would look great in a gallery.

Bjørn, there is some kind of magic in everything you do that is fascinating. Still trying to decipher it and learn. In the meantime, I enjoy it.
Thanks for sharing!

Even more surprising as this creature is completely sharp !
Also, the unusual white background accentuates pastel colours and diaphanous parts of this picture.

"Even more surprising as this creature is completely sharp ! "
I'm not the least surprised. We all too often consider the Heligons as poorly performing lenses because there are lots of chromatic and spherical aberrations present in our images. What we concomitantly forget is that these lenses are dedicated for a very special task, namely, acting as a relay system from an X-ray screen to a film, cine, or CRT device. In their time these lenses were very expensive and use a lot of high-refractive, high-end glass as well. However, also due to their strictly defined optical configuration and high speed, the prize in optical deterioration and aberrations is very significant once the lenses are used well outside their dedicated conjugate distances. I remember a film capture of a hydrodynamic lab model done in real time with the Heligon 50 mm f/0.75 on a high-speed lab camera and the TV images were high contrast and tack sharp.

I'm on the same boat with Paco. Thanks for sharing!
