Thank you both,
An preference on filter wheel or filter drawer?
I have QHY and ZWO filter wheels, i like the one from ZWO but not from QHY because it is an old version [Version 2], and i have many planetary ZWO cameras so i use a filter wheel also with mono cameras.
I have only one filter drawer, from Antlia, it is an amazing design, the only drawback or cons i think about it is the way of locking the insert inside the filter drawer, it is with screws, so if you never change the filter during imaging then this is perfect, but if you decided in the middle of imaging to change the filter then you have to unscrew, this is not good, even if you have multiple inserts you must screw and unscrew to safely lock it, i prefer if it is a knob or magnet type so i can easily unlock to change rather than using Allen/L keys.
