A close up and a wide field image of SH2 308
Located 5200 light years in Canis Major (The Dolphin Nebula) is an HII region. It is a popular subject in astrophotography.
Given the 4500 mm focal length of the CDK 700 the close up image shows a fair amount of the filamentary detail which has heavy OIII content. The DR 350 captures the entire nebula with the shape leading to the nickname The Dolphin Nebula.
