Description

The picture is rarely found in this composition, though this combination, I think, looks quite attractive.
The OIII-signal is very weak and was not visible on the Canon image, it comes 100% from the ASI camera.
The small round Ha-nebula with the blue OIII spot at the bottom center is LAN 21, a PN.
The two very small Ha nebulae west of Sh2-88 are LBN137 and LBN138.
