The Einstein Cross or Q2237+030

Hi All,

I have wanted to image this object for quite a while now and finally decided to go for it. Result is good but MUCH better seeing is needed if I am to resolve the actual lensed quasar

The Galaxy of interest is directly in the center of FOV

The quasar is located about 8 billion light years from Earth, while the lensing galaxy is located at a distance of 400 million light years.

First shot is using a willams optics FLT-132 and qhy-9 with 3 x 15min luminance shots
Second shot is using a 10" GSO RC with the qhy-9 also 3 x 15min luminance shots.

Happy with these results for now but will re-visit this in a darker sky position as i have been shooting over the top of Perth for this one.

Cheers,
Grahame.
