Features:
An internal filter wheel with custom RGB+C color filters is available as an option for color imaging with the STF-402M. The filters are designed specifically to yield a proper balance of both OIII and H-alpha emission line intensity from planetary nebula while at the same time giving an accurate while balance from continuum light from solar type stars in the same field.
The Mars image below shows a violet haze over the north pole (south is up) and a diffuse yellow dust storm in the southern hemisphere. The image was taken by Ed Grafton of Houston, Texas using an C14 telescope.
