Call for perseid images was created by Keith g
Hi all, with the ongoing rise of the nova in Delphinus, there seems to be a shortage of images of this area pre discovery.
Has anyone got images available taken around the Aquila/Sagitta/Delphinus area of the sky looking to catch a perseid? This is to see if the nova had been captured earlier than discovere, you could may well have a valuable image !!
Thanks,
Keith..

This from the BAA:
The discovery was made... on August 14.750 UT.
No star was visible on previous frames taken by the discoverer 13.565 UT to magnitude 13.0
Perseid Meteor patrol frames taken on Aug 14.063UT show nothing visible at the reported position to magnitude 9.0C
So the key times for pre-discovery images from anyone here are:
14.063 to 14.750
*or* prior to 14.063 if your images are below mag 9.0
*or* prior to 13.565 if your images are below mag 13.0
