William Optics RedCat 51 V2 APO 250mm f/4.9 - L-RC51II

Note: For DSLRs, it's highly recommended to use a William Optics T mount adapter in order to achieve proper focus.

For products such as Baader AstroSolar filters, the tube outer diameter is 81mm, which is suitable for This Size (#2469336) filter.

Dew Heater straps should be 10.25" or longer in length. The Kendrick #2007 Dew Strap fits well at 11" heated length.
