reprocessing my data from my very first dark site visit back in december last year. i’m always been a little disappointed when editing that data but i think i’ve finally got a final image i’m happy with.
44x120s images stacked in dss with no calibration. processed in pixinsight and photoshop.

i’ve targeted a lot of ha regions with my @altair_astro tri band filter of late. i decided it was time to see what i could get from andromeda with it. i was hoping to be able to isolate the hydrogen regions and i’m pretty happy that i’ve been able to do that. with some more data i should be able to control the noise some more so will look to collect that.
hope you enjoy a slightly different view of our neighbour andromeda.

Here are some more images from this year's royal observatory greenwich insight investment astronomy photographer of the year 2019 award, curated by new scientist's digital visuals editor, @davestockphoto. here are his thoughts.
william anders took the famous earthrise photo in 1968, but many photographers since – amateur and professional alike - have taken, i believe, equally inspiring photos that help us understand our place in the cosmos that little bit better.
there’s a lot of space out there and thanks to advanced cameras, computer and telescope technology, as well as access to remote scopes including the mars rover and hubble, there’s more ways than ever to view the universe outside our atmosphere. this years’ astronomy photographer of the year showcased some of the best views.
take, for example, the elegant elephant's trunk, by lluís romero ventura (image 3). ventura not only visualised an often-overlooked star-forming nebula, but dedicated a monumental amount of time to capture it, with the final image requiring 32-hours of exposure to allow enough light onto the camera’s sensor.
flower power, by brandon yoshizawa (image 2) required two exposures – one to ensure the foreground was sharp, and the other to capture what at first might seem like a flower-shaped firework, but is, in fact, a falcon 9 rocket launch from ejina, in mongolia, china.
across the sky of history, by w**g zheng (image 1), also taken in ejina, depicts silhouetted, euphrates poplar trees against the backdrop of our own galaxy – the milky way – as a meteor speeds across the frame.
my personal favourite is the watcher, by nicolai brügger (image 4). here, the norwegian town of offersøykammen bathes in snow and northern lights aurorae. i’ve never seen the northern lights, but i’m grabbing my camera and heading there just as soon as i can.
these images will be on view at the national maritime museum in greenwich, london.
