Something new. astronomical 3d-sculpures
I have been an astrophotographer for about thirty years, and for almost as long, I have been converting my photographs into various three-dimensional formats. My 3D images and animations are always based on real astronomical data. The result is an approximation of reality — never a guesswork creation.
I haven’t often published my 3D studies in my blog or on social media, since they usually require a special viewing method, such as Red/Cyan glasses, special viewing methods or stereoscopic displays, to be properly experienced.
Now I have begun working on a new series of physical artworks, where I transform my photographs into tangible 3D forms. In these pieces, viewers can perceive cosmic structures at a glance — the relative distances between stars and galaxies are represented as accurately as possible. It’s like sculpting on a cosmic scale.
Here are a few examples of my first prototypes. I’m using new and intriguing materials to manipulate light — to both reveal and conceal. I am especially fascinated by the idea of large, room-sized cosmic landscapes where the viewer can literally walk into space.
Videos offer some sense of my work, but in real life, even my smallest sculptures contain a sense of infinity. That’s difficult to capture in video, yet it’s there — quietly unfolding before the eyes.

ICARUS, a two frame vertical panorama
In this image, I have combined my new shot of the Witch’s Broom Nebula with my recent photo “ICARUS, the Final Flight” to form a two-frame mosaic. I love discovering fresh compositions from well-known targets — in this case, the beautiful Veil Nebula supernova remnant.

ICARUS, the final flight
My latest photo shows a small portion of the Veil Nebula supernova remnant in Cygnus. I have wanted to photograph this tiny, knot-like object for a long time, making it the main character of the composition. I couldn’t find any catalog number for this object — if someone knows it, please drop a comment and I’ll add it here.
After I stacked all the data and saw the full-resolution image for the first time, I had the strange feeling that I had seen this composition before. A moment later I realised what it reminded me of — an old painting of Icarus from Greek mythology.

Western Veil nebula, the Witch's Broom
This is my first-light image for the autumn season 2025.
I collected a total of 34 hours of exposure time over a period of about two months for this two-frame mosaic. The seeing conditions were relatively good for my location, with FWHM values ranging between 1.6 and 2.5 throughout the sessions.

An artwork for the Art Museum of Oulu
While waiting to get back to imaging, I completed an artwork commissioned by the Art Museum of Oulu.
This is part of the Art Cabinet project, and I was given complete freedom to fill the cabinet with my art.
The cabinet measures 120 × 110 × 65 cm and has two doors in the front and one on the top.
My idea was to evoke a sense of infinity when the doors are opened. To achieve this, I used the blackest paint in the world—Vantablack. I have photographed galaxies over the past 30 years, and I decided to use them to create a 3D representation of infinity.
Here are a couple of pictures, but the video will best show how successful I was.

A Planetary Nebula Purgathofer-Weinberger 1 (PuWe1) is the Last Photo for Now
I spent total 36 hours of collecting 20 min. exposures for this cosmic smoke ring with narrowband filters, H-alpha, S-II and O-III. PuWe1 locates in constellation lynx at distance of about 1300 light years.
This is my last new photo for the imaging season 2024-25, we ran out of the astronomical darkens at May 7. Deep sky imaging is possible again after the first week of September. up here 65N.

Soul Nebula, a Two Frame Panorama
I published yesterday a detail picture of the Soul nebula, IC 1848. Earlier this year I shot another long focal length photo of the IC 1848, those two photos are overlapping so I was able to make a two frame mosaic out of them, total exposure time 30h
