Features: Baader 110mm D-ERF Energy Rejection Filter With IR-Cut Dielectric Coating
- Extremely hard and scratch-resistant
- Coated using ion-beam systems to keep the heat load on the glass as low as possible
- Highest homogeneity with Plane-parallel circular disks having both sides optically polished
- Features an infrared-reflective coating that prevents the penetration of heat into the telescope tube
- The blocking of IR (heat radiation) holds the D-ERF filter plane-parallel even with longer observation times
- Fine quality raw glass construction to cope with the stresses of solar use while ensuring fantastic images and crystal clear observing
Note: Never use any eyepiece filter for solar observation without objective front filter
