Bessel61cygni

Hello Everyone, This site has given me some great answers in the past and always happy to see what folks are doing. I'm hoping someone might recognize this defect in the image below and maybe point me in the right direction. I've also supplied information that may offer clues. Does anyone recognize this odd pixel defect in the closer detail? Some day I think I might start a catalogue of defects and aberrations lol...

Fantastic! I know it sounds like a simple question but through me of after using my old Bresser. This is a much nicer scope and want to use it for photography eventually like others might do. Very thanks for the quick reply.

I recently bought a ZENITHSTAR 61 APO and found that my prior 1.25 Eyepieces will not work. Seems the like focal point is at a point beyond the max of the focuser. I can hold the eye piece out past it a bit and see it start to come into focus. Any recommendations?
