 174mini ASI174 mini is designed for Big FOV guiding. This is very useful in OAG to looking for a guide star. When you using OAG guider to work with Ritchey-Chretien or Schmit-Cassegrain telescope, the hardest part is to looking for a guide star. ASI174 mini have 1/1.2″ big sensor which means you can have  4 times bigger Fov than 120mm.


The Mini camera is very suitable for OAG since it has a much larger focus range than other ZWO cameras.
