I’ve spent the last month or so capturing wide field images with my Sigma 70-300 mm on my Celestron Nightscape. (Ok, so they’re really Fall Wide Fields.) With the stack of adapters I’m using to get from the Nikon bayonet to the T-ring on the Nightscape, I can only get to focus between 200 and 300 mm. At 200 mm that’s a wide enough field of view to capture the entire Andromeda galaxy and the full sword of Orion. The results turned out pretty decent.
