SL2SJ02176- 0513, ASW0003dq7 is the 1st example of real lenses in the Spotter' guide. Was discovered by the CFHT Legacy Survey and Subsequent high-resolution follow up imaging and spectroscopy were obtained. Many studies references are found in literature (cited in GZ forum)
I picked this image for a trial of SpaghettiLens: here is my modeling test with z lens=0.65 and z source=1.85 .
I'll be pleased to see any improvement by experts!
Some comments on the results and physics of this modeling case are strongly welcomed 😃

Here is my attempt, which is fairly similar.
The models depend strongly on where we put the counter-image at 3 o'clock. @C_cld posted a higher-resolution image of this object (from HST data) on the galaxy zoo forum earlier this year. There the counter image is clear.
