I have a Canon G2 4megapixel camera for sale. It is in mint condition with all original accessories and box. It also has a 49mm lens tube with a Hoya skyfilter in place. The lense tube would allow it to be attached via step rings to a telescope or an eye piece projection adaptor.
It cost 800$ new, I am asking 350$ shipped in CONUS.
I would consider a Tele Vue 35mm Panoptic in trade or a DSC computer such as Sky Commander or JMI. I might also consider a binoviewer.
I will take MO, cashiers check, or personal check allowing time to clear. I have excellent feedback both here and the other popular online auction site.
