On 25th Feb '26 I photographed the #EyesOfClavius #ClairObscur effect. This animation shows how much the Sun had risen over #Clavius between 18:01 and 19:40UT. #WilliamOptics 70mm refractor, #ZWO #ASI120MC camera, #Televue #Powermate5x. #Oxfordshire, UK

Here is my stacked image of the #EyesOfClavius, taken at 18:08 UT 25 February 2026 from #Oxfordshire, UK. #WilliamOptics 70mm refractor, #ZWO #ASI120MC camera, #TeleVue #5xPowermate.

Just a quick heads-up that the #EyesOfClavius will be visible from around 18:00 UT TONIGHT (Wednesday 25th February). I love this lunar #ClairObscur effect and it's always a fun one to observe.
