Data Acquisition Method: Personal Telescope Setup

Description and Details: This image spans a projected region of approximately 135 × 90 light-years, assuming a distance of about 2,500 light-years to the Orion–Monoceros molecular complex. The field contains a concentration of nebulae and stellar groupings located within the same large-scale molecular environment.

IC 2169, also known as Dreyer’s Nebula, is a reflection nebula listed in J. L. E. Dreyer’s Index Catalogue, compiled as a supplement to the New General Catalogue in the late 19th century. Its bluish appearance results from starlight scattered by interstellar dust, in contrast to the surrounding emission-dominated regions.

Also present in the field are NGC 2245, NGC 2247 and IC 446, compact nebulae embedded in the same complex.
