Welcome Merlin, I do a visual S/N search using a 40cm Dob from my observatory in the Upper Mary Valley, inland from Caloundra Queensland, I mainly observe galaxies from 30deg south as they are not visible from northern hemisphere automated surveys,there are other guys up here who do CCD imaging,who I am in contact with if I need to check a suspect object.
Are you a wanting to start S/N searching, or are you already doing it?. Cheers astroron
