Product DescriptionThis adapter can be used on all uncooled ASI cameras to reduce the back focus distance to around 5mm so you can focus on some very short back focus scopes such like PST Please note : when you open the camera, make sure it is on a flat surface with the lens pointed upwards. If it is not in this orientation the glass that shields the sensor may fall out which can cause dust to get on the sensor. just unscrew the old cover off and screw in the new one PS: this new cover can not hold the protect window of ASI174MM/MC, so you need an external 1.25″ filter |
