Orion filter wheel for five 31,7mm filters

 The Lacerta filter wheels are ideal for both visual and photographic work. Depending on models, accepts 5 or 9 pieces of 1.25" standard filters, or 5 pieces of 2" standard filters.

For visual observation, these filters might be:
- for deep/sky observers: CLS, UHC, OIII, H-beta and position without filter
- for planetary observers: different colour and contrast filters

For photographical work:
- with monochrome camera L, R, G, B and IR filters
- for deep-sky astrophotography; L, R, G, B, H-alpha; or a narrow-band series consisting of: H-alpha, OIII, SII, H-beta and L

The 1,25" filter wheels are connected to both the focuser and the eyepiece with T2 thread or 1,25" adapters (included), while the 2" filter wheel connects with M48 thread or 2" size adapters.
