ZWO EFW 7x36mm (2nd Gen)

A well made piece of equipment. I have mine paired with a ZWO ASI294MM and it has performed flawlessly now over 8 nights of imaging.

ข้อดี: Well made.
Filter masks included.
If you are using it with a ZWO camera you probably will not need any additional adapters to connect to camera and scope and achieve correct backfocus.

ข้อเสีย: None.
