The following image of Caroline's Rose was taken by Mike Lancaster on the 6th August 2024. The image comprises 63 x 10 second exposures taken using an Altair Hypercam 26C at 300 gain (plus darks, flats and flat darks), through an Orion Optics UK AG12 Astrograph mounted on an EQ8 mount. A 0.95x Wynne Corrector and Astronomik CLS-CCD filter were also employed. Due to the short exposures no guiding was employed. Images were acquired using SharpCap, and the processing was entirely performed in PixInsight. Image Credit: Mike Lancaster. |

| Chris Newsome took this image of NGC 7789 in the early hours of 24th July 2006. He used a Celestron C8-NGT and a Canon EOS 300D camera fitted with an Astronomik CLS filter. This set up was guided via a Meade DSI camera and a Skywatcher 80T telescope using a GPUSB autoguider interface controlled by MaximDL. The image comprises ten 360 second frames at 200ASA, calibrated and combined in MaximDL and then processed in CS2. This image made Picture of the Week on the British Astronomical Association (BAA) website in July 2006. Image Credit: Chris Newsome. |
