Stars in map up to visual magnitude 6.0
Herbig Ae/Be stars, first identified by Herbig (1960), are now commonly accepted to be intermediate-mass premain-sequence stars. They are associated with nebulosity and are surrounded by circumstellar material resulting from their formation process. V633 is one of those kinds of stars with the Herbig-Haro objects HH 161 and HH 164 forming parts of the Horseshoe-shaped loop emanating from it.
At 222x the star V633 Cassiopeiae looks slightly "out of focus" or like a small hazy star. Using averted vision I was able to notice some of faint nebulosity very close, in fact connected with the star to the east. V633 Cassiopeiae along with the Herbig-Haro objects associated with it are easy to find because they lie roughly 25 arc minutes to the southeast of the bright 2.3 magnitude star Caph (β Cassiopeiae), one of the components of the famous constellation Cassiopeia. To the west in the field, the reflection nebula vdB1 engulfs three stars.
At 296x, V633 Cassiopeia looks embedded in a faint nebula, little contrasted against the background sky.
