Yup. Otherwise known as the "Double-Double", they're a great pair to test optics and seeing.

The double double is quite a common 'how low can you go' pair.

To split the close pair usually take about a magnifcation of x100 but I have got them at x72 on nights of good seeing.

Some people claim they can do them at x50 but I have never achieved this.

Cheers

Ian
