Soap Bubble Nebula, Ju 1
This beautiful and symmetric planetary nebula drifts in the constellation Cygnus at a distance of about 4,000 light-years from us.
Ju 1 (PN G075.5+01.7) was discovered in 2007 by amateur astronomer Dave Jurasevich.
With an angular diameter of about 260 arcseconds, the nebula is extremely faint, and its position against a backdrop of diffuse emission made it particularly difficult to detect.
My image of this planetary nebula has a total exposure time of 35 hours — 30 hours in O III and 5 hours in H-alpha — captured over several nights between 20 October and 17 November 2025.

The emission from H-alpha is seen as red, blueish tones are from an emission of ionized oxygen, O-III. This combination is very close to a visual colors of the nebula.

New book with Sir Brian May is out!
ISLANDS IN INFINITY, GALAXIES 3D
Buy a copy (UK store)
https://shop.londonstereo.com/islands-in-infinity-galaxies-3-d.html
You will be able to purchase the book directly from me as soon as the copies arrive here — in about two weeks or so. I’ll announce the opening of my online book shop both on social media and here.
From left to right: Prof. Ward-Thompson, Sir Brian May and yours truly
Our new book was published at the Museum of Brands in London on Thursday, 13 November 2025.
What a hectic and wonderful experience with the whole book team and a large, enthusiastic audience.
This is the first book in the world that lets readers see the real shapes of galaxies and galaxy groups in true 3D — a completely new way to understand cosmic structures.

ISLANDS IN INFINITY: GALAXIES 3-D
by Brian May, Professor Derek Ward-Thompson, J-P Metsävainio,
published by The London Stereoscopic Company, 13 November 2025 https://shop.londonstereo.com
Islands in Infinity is the first book to explore galaxies in stereoscopic 3-D. Created by Brian May (PhD in Astronomy), Professor Derek Ward-Thompson (galaxy expert), and astro-photography master J-P Metsävainio, it offers a groundbreaking visual journey through the cosmos, accompanied by compelling narrative.
Featuring more than 200 colour images from the world’s leading land- and space-based telescopes, along with over 80 original artworks, Islands in Infinity delivers a breathtaking 3-D introduction to the formation, nature, evolution, and classification of some of the 200 billion galaxies that fill the observable Universe. The use of stereoscopic technology allows us to see deeper into galaxies and gain insights never before possible.
Readers are taken on an extraordinary voyage through the weird and wonderful shapes of colliding and merging galaxies, witnessing their chaotic transformations. Moving toward the edge of the visible Universe, the book explores how galaxies gather in clusters and superclusters, looking outward—and back in time—toward the dawn of the cosmos and the Big Bang itself.
Each copy comes complete with a Lite OWL Stereoscopic Viewer, designed by Brian May which will bring the images to life in the magic of 3-D.
Sir Brian May says - For the very first time, readers will be able to enjoy stereoscopic renderings of galaxies previously only seen as flat ‘mono’ images. And this, coupled with a text from one of the world’s experts on the evolution of galaxies, will give a uniquely new insight into the Universe as it is now perceived. Moreover, it’s an account understandable and enjoyable by anyone interested in the biggest subject in the Universe - not just astro experts. It will be a gripping read !!
Professor Ward-Thompson says - In this book you will, I hope, find everything you need to understand what galaxies are, how they originated, how they have evolved into many different types of galaxy, and how they interact and give birth to everything we experience on our tiny blue planet inside our Solar System, itself inside our very own Galaxy, the Milky Way.
J-P Metsävainio says - I undertook a major but deeply rewarding task: converting a vast number of galaxies into 3D stereo while ensuring that every detail remained as scientifically accurate as possible. It was truly thrilling to watch these complex structures come to life before my eyes as I saw them in three dimensions for the first time. Galaxy clusters revealed their true nature, with accurate relative distances, and delicate dust lanes appearing to float in front of the galactic discs. I felt as if I were holding the universe in my hands — and I hope readers will share that same eye-opening experience through the pages of this book.

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.
