Astronomy Photographer of the Year 2021 Set of 2 Magnets

Regular price £5.00 Sale

This set of magnets feature two images from our Astronomy Photographer of the Year competition.

"The California Nebula, otherwise known as NGC 1499, was captured over seven nights in 2021 using broadband and narrowband filters, with a total integration time of 16.1 hours. I had captured NGC 1499 previously, but I was so excited to see what my new camera was capable of producing on one of my favourite deep-sky objects using narrowband filters. The results far exceeded my expectations. The raw data was pre-processed and the stars were removed using a tool called Starnet, then later replaced during post-processing with the more naturally coloured stars from the RGB (red, green, blue) data. In this Hubble Palette version the hydrogen-alpha is mapped to green, singly ionized sulphur (SII) is mapped to red and doubly ionized oxygen (OIII) is mapped to the blue channel. While the colours in this image are not the true colours, the narrowband filters reveal much more of the hidden gasses not visible in a broadband image."

"The colour tones and the lines are really amazing in this panorama of the Milky Way over the lavender fields in Valensole, even though the light pollution is clearly visible over the whole area. I captured the foreground in the blue hour (twilight) with a high ISO value because the lavender never stands still and long exposure times during the night are not possible. One hour later, when the Milky Way was low in the sky, I captured the arc with a star tracker in the same location."
