Vår expertkommentar:
RedCat 51 är nog ett av de mest omtyckta Apo-teleskopen från William Optics, och det är inte utan anledning: Det levererar perfekta astrofoton av deep sky-objekt och är mycket lätt att transportera tack vare sin blygsamma storlek.

The RedCat 51 is probably one of William Optics’ most loved apochromats and not without good reason. It delivers perfect astrophotos of deep-sky objects and is easily transportable due to its small size.
