Photo of the Week for November 27, 2015
The deep-sky contains wonders both bright and showy, as well as faint and subtle. This pairing in Perseus has fine examples of each. The famed Double Cluster (lower centre) is one of the sky’s showpiece objects and a delight in binoculars. Nearby is the nebula pair known as the Heart and Soul nebula (IC 1848, to the left, and IC 1805) — a challenging visual target, but rendered vivid in long-exposure images like this one by Luc Bellavance from Rimouski, Quebec.
To capture the scene, Bellavance used a Canon EOS Rebel T1i DSLR camera set to ISO1600 and equipped with a Astronomik CLS CCD light-pollution filter and Tamron 90mm, f/3.2 lens. The finished photo consists of eighteen, 4-minute frames (for a total exposure of 72 minutes) combined digitally.
