About this Image

This apparently close pair of a planetary nebula and a globular cluster is situated in the Constellation Scutum.
The globular cluster NGC 6712 at a distance of 22000 light years is embedded in a dense milky way star field.

Apparently at a distance of 24 arc min the multiple shell elliptical planetary nebula IC 1295 is situated. It is shining in the intense blueish O-III emission line at a distance of 3200 light years, its apparent diameter is 1.7 arc min. It is resembling the blown-off gas shell of a dying star. The target has not been imaged frequently.

North is to the top right corner.

Below you see a crop on the planetary nebula in 50/100% size.
