Sharpless 88 is fairly bright with some other smaller nebula seen just to the left of the main nebula. The nebula itself does very well with a hydrogen-alpha filter but to get the fainter area around it, you will need a long exposure. The small nebula just to the right of SH2-88 would do well with a larger telescope and these should resolve very well. With a larger field of view, you can easily capture SH2-87 and SH2-88 together as seen on the Web Page Button.

This nebula associated with the Vul OB1 association consists of three regions - star formation began in a diffuse large nebula Sh 2-88A, then spread to the compact HII region Sh 2-88B1, ionised by an O8.5-9.5 V star, and then finally spread to the ultracompact Sh 2-88B2, ionised by a star dimmer than B0.5 V.

Avedisova lists three ionising stars: the O7 V star HD 338916, the O8.5 Ib supergiant HD 338926, and the B0.5 V star LS II +25 09.
