This is a compact but unique-shaped galaxy NGC4088. You can find out the galaxy around the midway of M106 and M109. The galaxy has a long axis of 6 arc minutes, a dimmed elliptic light can be detected through medium-sized telescopes.
This galaxy has been classified in spiral galaxies but it has also some features of bared galaxies. It can be seen that NGC4088 has a pair of S-shaped stretched arms and another pair coiled up tightly.
A compact edge-on galaxy about 10 arc minutes south of NGC4088 is NGC4085.
