ZWO Darkening Ring Set for 461MM-P
This darkening ring set from ZWO will help owners of the impressive medium-format ASI461MM-P camera eliminate light leaks in the imaging train. This kit includes four darkening rings, and is designed to be used in conjunction with the ZWO EFW-7X50 filter wheel and OAG-L-68; blocking possible light bleed between these accessories and the camera. Each spacer is only around 0.2mm thick, ensuring that backspacing is minimally impacted - with less than 1mm of increased backfocus distance when all four spacers are installed.
