The sky was clear and crisp last night and the waxing gibbous moon was sharply outlined. I wanted a really tight shot of the moon to combine with other backgrounds. This requires a focal length close to 2000mm. I tried a variety of combinations of lenses and telextenders, but the final image below was made with a very inexpensive 1300mm lens by Samyang. The optical quality of this lens is what you would expect from such an inexpensive product. Nonetheless, it was good enough to achieve a tight shot that I was able to clean up and enhance later in post-processing.
