Are there any higher resolution images available?
Generally, the images on the NAOJ website are of the highest resolution available.
Why are so many of the astronomical images taken by the 50-cm Telescope for Public Outreach in low resolution?
This is because the CCD camera sensors available from the 1990s to the early 2000s when these pictures were taken had only a limited number of pixels. Therefore, no higher resolution images are available.

Have there been any changes in the usage rules for NAOJ’s copyrighted material?
We revised the Terms of Use for the NAOJ website on April 17, 2017. This revised version allows you to use our copyrighted material without permission in many cases. These terms may be further revised without prior notice.
In March 2022, we restructured our Terms of Use into four pages: “Website Terms of Use,” “Usage of Copyrighted Material,” “Privacy Policy,” and “FAQs.” Regarding the use of our copyrighted material, we have broadened the scope of free use, deleted the provisions on reporting the use of copyrighted material and sending book copies, and made the descriptions easier to understand, thereby improving user convenience. No modification was made to the provisions related to credit indication and material modification.
