About this image

A two hour collect against the target Callum suggested a couple of months back.

I've more data to add but this is a starting point.

Quite a nice night. Dark, clear, good seeing. Shame I dozed off in a chair.

Definitely there, in my opinion.  The brightest portion of the horseshoe is very clearly visible to the upper right of the lensing galaxy.

Interesting account Grant of your successful attempt at this challenge. I find the lensing effect more apparent in the full scale image than the zoomed-in segment, as it's less pixelated.
As you say, next time more coffee or a couple of matchsticks to help you stay awake :-)
