Adaptoare Husa cu profil ingust

This adapter can be used on all uncooled ASI cameras to reduce the back focus distance to around 5mm so you can focus on some very short back focus scopes such like the Coronado PST.

Easy connection: just unscrew the old cover and screw in the new one.

Note: this new cover cannot hold the protect window of the ASI 174 MM and ASI 174 MC, so you need an external 1.25″ filter.
