Deneb

Deneb is a tritave-repeating rank-2 temperament that tempers out the comma 6655/6561 in the 3.5.11 subgroup, the amount by which 4 11/9's exceed 11/5. Having a generator of ~11/9, it possesses MOS scales of the families 1L 4s<3/1>, 5L 1s<3/1>, 6L 5s<3/1>, and 11L 6s<3/1>. Good tunings for this temperament are 11edt, 17edt, 28edt, 39edt and 45edt.

Harmony

Deneb does not have sevens and as such the most simple approach to no-twos harmony (using the chord 3:5:7) does not work. Due to its approximation of 11/9 and 11/5, the chord 5:9:11 and its utonal inversion 45:55:99 is well-represented. The utonal chord in particular sounds surprisingly consonant for a no-twos chord, while the otonal chord sounds more strained but still somewhat consonant.
