AVS NANO-TEC custom cameras are the only Peltier thermoelectrically cooled cameras in the world made in the 1.25" eyepiece form factor .
AVS NANO-AIR are forced air cooled cameras designed to reduce imaging sensor noise thru cooling to ambient temperature by forced air flow .
They are identical in all other respects to the NANO-TEC except for the missing Peltier cooling system .
AVS NANO cameras can be made parfocal with most eyepieces .
AVS NANO-TEC and NANO-AIR are compatible and come to focus without any modification in any telescope that could use a Plossl eyepiece .
AVS NANO-TEC and NANO-AIR cameras are compatible with all solar scopes such as Meade Coronado PST .
All AVS NANO cameras have very low read noise and in addition the -TEC version dark current and dark noise is dramatically reduced for highest performance .
