This is the filter dedicated to ZWO cameras. So it is called “Z Series”.
- Fits ASI M42-interface cameras (APS-C or smaller sensor except 2600MCPro)
- The set includes 2 pcs of spacer rings for the proper spacing adjustment
This new, very interesting nebulae filter is transparent to the spectral lines H-beta, OIII, H-alpha and SII - and with very high transmission! It is therefore ideal for photographing large nebulae, allowing the typical colours of these objects to pass through and blocking the disturbing sky glow. In particular, the filter quickly cuts off the near infrared, completely up to 1100 nanometres. This is important because cameras are sensitive to this range, but telescope optics are optimised for the visible spectral range and are faulty in the infrared range.
The Nebula Booster is particularly suitable for fast lens optics, which are preferred for astrophotography of large fields. The filter glasses are 2.5 millimetres thick. It can therefore be exchanged with other 2.5 mm thick IDAS filters without changing the focus position.
