Wide field imaging

During the morning of the 13th December 2025, numerous time-lapse images were taken of various regions of the sky in an attempt to capture some Geminid meteors using a Sony ZV-E10 Vlogging camera fitted with a Sigma 23mm F1.4 lens. The camera was mounted on an MSM tracker following sidereal motion to cover the radiant of the meteor shower near Gemini. During this particular run, some 14 x 30s exposures were taken at F2 and ISO 800, with the wide field camera recording an area of sky covering some 61 x 41 degrees. The images were integrated with flat fields and Bias adjustments within Pixinsight, with final adjustments made in Adobe Lightroom. The combined 7 minute exposure highlighted the densely packed are of one the spiral arms of our galaxy, rich with many colourful areas of nebulosity, with the planet Jupiter shining dazzlingly brightly close to the stars Castor and Pollux in Gemini. The image was annotated in both Pixinsight and Astrometry.net with Pixinsight registering 50,000 stars in the field of view.
