DescriptionI'd configured the Askar V to capture the Question Mark Nebula. Couldn't resist framing this stunning image on the same evening, with the same rig. I love the way you can see the dust lanes connecting the Cave Nebula to the other structures including the Bubble Nebula. The Lobster Claw Nebula was an unexpected bonus
