Crescent Moon: A 4% illuminated 1.4 day old waxing crescent Moon was imaged between clouds prior to it setting. The planet Mercury was just below it next to open star cluster M44 (Praesepe), but these were lost in the late evening twilight sky. The images were taken with a Sony ZV-E10 Vlogging camera fitted with a 70-350mm zoom lens set at full zoom at F6.3, ISO 800 and 1/120s and 100mm FL at F5.6, ISO 160 and 1/1/10s. The single images were processed in Sony Imaging Edge and Adobe Photoshop 2024.

First Starlight on an old scope: Following the refurbishment of a newly acquired second hand William Optics Zenithstar 71mm doublet refractor, it was tested on the night sky for imaging using an ASI 533MM Pro camera fitted with an 8 position filter wheel. The scope was attached to an iOptron CEM26 mount guided by a QHY5L-IIM guide camera fitted to an SVBony 165 guide scope. After balancing, polar alignment and guide calibrations, some sample DSO objects were taken using NINA to captured FITS files to appraise the repair of the scope's optics. The resultant images were then integrated and processed in Pixinsight which produced reasonable results, however the lack of a field flattener required the images to be cropped and further processed to avoid severe peripheral distortion of the star fields.
