Q0957+561 A/B next to NGC 3079 - a 8.7 billion lightyear deep view from my backyard

This is certainly not the best picture I have taken, nor is it particularly well processed. But it clearly shows Q0957+561 A/B, the so called twin quasar. Q0957+561 A/B is the first known gravitationally lensed object, discovered in 1979. The QSO is at z=1.41, i.e., 8.7 billion light years (or 2.4 Gpc) away! The two gravitationally lenses images A and B ar 6" apart and have a magnitude of 16.7 in V. I continue to be amazed, and find it extremely cool, that one can peek 8.7 billion light years deep into space and detect something, with amateur equipment just from your backyard!

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
