|Main Tube Length||24.2in||615mm|
|Main Tube Diameter||2.6in||67mm|
|Objective Clear Aperture Diameter||1.6in||41mm|
This telescope has a parallel brass barrel, covered in brown leather. The objective lens is an achromatic doublet, contained in a nickeled silver cell. The objective has an extendable sunshade. All metal parts are nickeled silver. It has a single draw, a four-lens eyepiece, and a bulbous eyecup. It is signed "Dollond London Achromatic Night" on the eye tube draw, with the eyecup to the right. There is a long-necked bird design below the signature. The creature is resting on a crown. This designation as a "night" telescope is quite rare; the eye tube is oversized allowing larger diameter optics to be used for better night vision.
