Einstein’s Cross with EAA?

Just wondering if anyone has attempted to observe Einsteins Cross with EAA, or any other examples of gravitational lensing?

Hi,

Visually, parachute seen in my 20" (former), and in a 24" Dob Einstein Cross is doable. I suspect therefore that using EAA technique both should be able to be observed.

I always forget to try for these.

Thanks for the feedback and CN links, clearly there has been some hot discussion about this subject over the years!  

One of these nights I will dust of the C11 and give it / them a go!

The Cloudy Nights February EAA challenge had the Twin Quasar in Ursa Major as one of the objects. It is a gravitationally lensed quasar.  The distance is an amazing 8.7 billion light-years!

The Quasar is highlighted in yellow in the image I took below.

Great feedback Xio, I will give that one a try!

It never ceases to amaze how such distant objects can be seen with EAA. So the light from that quasar has been travelling for over 60% age of the universe or about twice the age of the Earth!

I'm sure this has been asked before but I wonder what the most distant object is that has been observed with EAA?
