ZWO 2-Inch Filter Drawer

Nice add-on to allow Dual-Band filters for imaging with ZWO OSC's. Wish I'd purchased the following as well, ZWO 2"-1.25" Filter Adapter Ring. I have older filter's in this format, that l could use in the 2-inch filter drawer. Delivered intact, and on time.

Great addition

This product allows me to use single filters in my image train while maintaining proper backfocus distance.

Magnets could be stronger

Everything attached to the scope perfectly. While the magnets hold my filters in the drawer, the magnets seem a bit weak. Stronger magnets would easy my mind a bit about losing a filter holder in the dark.

Convenience and speed when changing filters

I purchased this filter drawer to use with my ASI533mc Pro. It fit into my image train and enabled me to maintain the 55mm backspace based on the diagrams on the ZWO site. It makes changing filters very easy and does not require breaking down my image train to swap out a filter. I ordered an extra drawer so I can quickly swap out filters when needed. For example if I switch targets from star cluster to nebula and want to change the filter I am using on the target.
