This is quick image of the waxing gibbous moon taken last night during dusk. This is one of a series of test images that I and taking to explore the imaging characteristics of the Unitron 510. One nice feature of these long focal length refractors is that they give an excellent well corrected field with little chromatic aberation. (Photo credit: John Graham, 7/29/2023)
