Heart and Soul Nebula IC1805
Heart and Soul Nebula IC1805 in Hydrogen Alpha. I used a Canon 75-300mm lens set at 100mm. The Canon lens is attached via a Geoptik adaptor to an Atik 460EX mono camera.
This image consisted of 10 x 600 second exposures taken on a Skywatcher EQ8 mount. The images were unguided, but I did see some drift across the exposures so I would guide next time.
It’s really difficult to focus precisely with a standard Canon lens, especially in Ha when you need greater exposures to make out the stars on the screen.
