I have for sale a nearly new QHY filter wheel, CFW2-M-US. This is the ultra slim version, just 17mm added backfocus. The filter wheel has only been used a handful and times and is in perfect cosmetic and working condition.
Originally the filter wheel came with a 7 position 36mm filter disk, and I also bought a 5 position 50mm filter disk. Both are included.
$599 AUS including shipping and paypal fee. Note: ships from USA
