محول 75 مم ذكر إلى 48 مم ذكر/أنثى (SFA-M75M48F48-004)

The 48mm female filter threads on this adapter are a nice bonus, letting me attach my light pollution filter directly without extra rings. It threaded onto my camera perfectly and the 4mm extension gave me just enough back focus for my field flattener.

Threads were exactly as stated—8 mm on the 75 side and 6 mm on the 48 side—so spacing to my flattener came out perfect. The extra 4 mm of length let me hit focus without any extra spacers, and the female filter threads on the other end are a nice bonus.

Finally got my ZWO ASI cooled camera to thread perfectly onto my telescope's focuser using this adapter. The 48mm female threads on one end and 75mm male on the other solved that awkward gap I was fighting for weeks.
