Description

Like M 56, M92 is an old globular cluster where the stars contain hydrogen and helium, almost exclusively. It is around 27,000 light years from Earth and  contains around 330,000 stars. It was discovered by Elert Bode in 1777 [1].

The ancient clusters, which orbit the core of the much younger Milky Way are both fascinating and have a beautiful simplicity.

I spent two nights on this, back in August, but had problems on the first night. I'm still not sure whether it was camera tilt or mirror flop. Having had a month of clouds I went back to this and tried processing only the first night's subs; another night would improve it but for an hour and a half integration, I'm fairly pleased.
