Hi Lydia and Silv
It is indeed a great capture.
The BOSS team take many thousands of images per month of several hundered target galaxies. Stu doing the bulk of the work with some 3000 images in just a few nights.
The target galaxies are made up largely of spiral galaxies that are typically within about 250million light years. We try to image the script of galaxies regularly with images taken every few days where possible in order to achieve exactly what Stu has done here. This has significant scientific value for professional astronomers who may follow up the supernova. They are keen to know how young the Supernova might be and knowing that it wasn't there (to our magnitude limit) in say the last 7 days is very useful.
So NGC7531 is just one of those many galaxies in our lists that in this case gave very good rewards.
