Description

Sh2-132, also named the Lion nebula is 10,000 to 12,000 light-years away, located in the Perseus arm of our Galaxy, with a size of more than 250 light years. On our sky is located on the border between the constellations of Cepheus and Lacerta. It is interesting that this image contains two Wolf-Rayet stars - WR 153ab near the "wall" structure in the lion's head an WR 152 in the blue dominated part of the nebula. The Wolf-Rayet stars are very big, bight and hot stars with strong solar winds. These winds are so strong that eject huge amount of mass from the stars - something like 10 Sun masses per million years. The extreme nature of the Wolf-Rayet stars always dominate the nearby regions and lightening the surrounding area. In this case there are two of them and they are helped from 5 small open clusters of young stars to show us something very beautiful.

This project is my personal integration time record - 20h 55min The object is quite faint, but is still in reach for the workhorse about wider fields - the trusty 80mm refractor.

The first revision is the processed Ha stack.
