West Mountain 0.9-m Telescope

Filters

We have not fully tested any of these filters at this point to give exposure estimates.  That will come with time.  We can have 8 filters in at any one time, but want to limit filter changes.

  • Johnson/Cousins BVRI (Astrodon Photometrics) (scan)
  • H-alpha (3 nm wide and 21 nm wide)
  • H-beta (3 nm wide and 15 nm wide)
  • Clear Filter
  • Other narrow filters (O III, S II)
