COMA CORRECTORS

(6 products)

Coma correctors are essential accessories for Newtonian telescopes with fast focal ratios, a flat field and a small obstruction caused by the secondary mirror. These factors contribute to coma, an extra axial aberration that makes stars appear elongated or like comets.

We stock Baader & Sharpstar MPCC multi-purpose coma correctors for scopes with fast focal ratios between f/3-f/7, as well as SkyWatcher aplanatic coma correctors for f/4 & f/5 scopes.
