Description

Reflection Nebula VdB99, H-Alpha Nebula Sh2-1 and Sh2-7 in Constellation Scorpius

Sh2-1: This combination of HII region and reflection nebula is ionised by the B1V class star Pi Scorpii (HIP78265). Sh2-1 is a member of the nearby upper Scorpius subgroup of the Sco OB2 association.

The Sco OB2 association is part of the [url= http://galaxymap.org/detail_maps/gould.html] Gould belt [/url] and the inner edge of the Orion spur.

Sh 2-7: Is the core of a huge diffuse nebula and is ionised by the B0.2IVe subgiant binary Delta Scorpii. Delta Scorpii is a member of the nearby Sco OB2 association.

Both Sh2 objects are approximatly 650 light years away.
