Huge 2.2 Gigapixel Picture of the Milky Approach Was Taken in Simply 4.5 Hours

Accomplished astrophotographer Bartosz Wojczyński has created a huge 2.2 gigapixel photograph of the Milky Approach that he was capable of seize in only one evening, which is an astounding achievement on condition that a similar 1.7 gigapixel photo took one other photographer 12 years to finish.

A zoomable, in-browser model of the photograph will be discovered here.

The huge {photograph} was captured with a twin telescope setup: two Takahashi Epsilon 130D astrographs (focal size 430mm, f/3.3) and two Nikon D810A cameras, mounted on a Losmandy G11 astrophotography mount on the Tivoli Astro Farm in Namibia.

“The telescopes have been positioned at a slight angle relative to at least one one other, which allowed capturing two separate areas of the sky on the identical time,” Wojczyński tells PetaPixel. “The whole value of this gear is roughly $25,000.”

Wojczyński says that the complete, last decision of the photograph is 53,480×41,010 pixels and takes over 13 gigabytes on one onerous disk. The ultimate photograph is a composition of 110 mosaic panes (55 per telescope) and the publicity time was 4 minutes per pane at ISO 400 beneath what Wojczyński describes as good observational situations — no detectable mild polution, excessive elevation, dry air with wonderful transparency, and all synthetic satellites in shadow.

“I used Microsoft ICE to sew particular person panes right into a mosaic after which Photoshop for distinction and saturation changes. The quantity of post-processing was very mild so far as astrophotography goes,” he says. “First, as a result of DSLR photos taken beneath very darkish skies come out pretty usable proper out of the field, and second as a result of working a two gigapixel picture via any superior algorithms would require insane quantities of processing energy.”

This good set of situations allowed Wojczyński to not solely seize all the mandatory pictures in a bit greater than 4.5 hours in only one evening, but additionally produce a last picture that’s even bigger than the one that took J-P Metsavainio 12 years to complete.

“Remarkably, the complete pictures session took simply over 4.5 hours throughout a single evening on Could thirteenth, 2021,” Wojczyński says. “That is very brief in comparison with different related gigapixel initiatives, and made potential by the truth that I used to be utilizing a twin setup aimed on the brightest area of the evening sky, so extraordinarily lengthy exposures weren’t needed.”

Wojczyński says that as a result of he used DSLRs and never devoted astrophotography cameras, the evening sky is proven in its pure colours and the way the human eye would see it if it was delicate sufficient to mild.

“The Milky Approach comes out yellow-orange, as that is the dominant star coloration in our galaxy. The colour of the nebulae is brought on by ionized hydrogen which emits most of its mild within the pink a part of the seen spectrum (H-alpha, 656 nm wavelength),” he says.

The above video is titled “Gigapixels of Milky Approach” which Wojczyński says is impressed by a video known as Gigapixels of Andromeda, which is a 2015 video that showcases a 1.5 gigapixel photograph of the Andromeda Galaxy.

Wojczyński welcomes viewers to check out the complete decision photograph on his website and is providing prints that are up to 78-inches in length (two meters). For extra from Wojczyński, be sure that to observe him on Instagram or take a look at his website.
