- Lunar Orbiter 1's Frame O26 Med shows Dubyago (near the top left corner of photograph) and craters [/Liouville Liouville] and [/Respighi Respighi] (north of the dark mare-like region [/Schubert Schubert] N). Note the [/Concentric%20Crater Concentric Crater] south of [/Liouville Liouville]! (immediately east-southeast of [/Schubert Schubert] N).
- Lunar Orbiter 1's Frame 027 Med shows the Concentric Crater immediately southwest of Dubyago. This Concentric Crater (item N°11 in C.A.Wood's list published in 1978) was also captured on Apollo 15's orbital Panoramic ITEK-frame AS15-P-9786 (scroll to the right).
- Apollo 16's orbital Panoramic ITEK-frame AS16-P-5152 also shows the Concentric Crater immediately southwest of Dubyago. The Concentric Crater itself is noticeable near the right margin of the frame.

Description
Dubyago is one of a number of mare lava flooded craters that are part of [/Mare%20Undarum Mare Undarum]. This area is like a miniature [/Mare%20Australe Mare Australe] and makes me wonder if there is an ancient undetected basin there. Dubyago's central peak is completely invisible (covered by lava?) and the terraces are largely smoothed out. The Orbiter image suggests that the crater on the floor of Dubyago may be a concentric crater - it seems to have an inner ring, but it looks flooded too. - tychocrater tychocrater Jun 30, 2007

- Nearby concentric crater, immediately southwest of Dubyago. Note that there's another Concentric Crater south of nearby crater [/Liouville Liouville].
Nomenclature
- The current IAU name honors two men:
- Dmitry Ivanovich Dubyago (September 21, 1849 - October 22, 1918), a Russian astronomer and expert in theoretical astrophysics, astrometry, and gravimetry.
- Alexander Dmitriyevich Dubyago (December 5, 1903, Kazan - October 29, 1959), a Soviet astronomer and expert in theoretical astrophysics.
- The name [/Neper Neper] A ([/Schubert Schubert] A to [/Julius%20Schmidt Julius Schmidt]) was Catalog Number 7 in Mary Blagg's [/Collated%20List Collated List] and in the original IAU nomenclature of [/Named%20Lunar%20Formations Named Lunar Formations] (1935), where the designation is attributed to [/Beer%20and%20M%C3%A4dler Beer and Mädler].
- The replacement name Dubiago was proposed by Arthur and Whitaker in the [/Rectified%20Lunar%20Atlas Rectified Lunar Atlas] (1963) and approved by the IAU in [/IAU%20Transactions%20XIIB 1964], with the biographical information published in Menzel, 1971.
- The spelling was changed to Dubyago at an unknown later date.
