Dual rig on the Iris

[Whistlin Bob]

Managed to sneak an overnight run on the Iris nebula last week, after a bit of scope DIY. I've used blackboard paint on all of the interior shiny bits of my Quattro 150, plus fitted a primary mask. Note to Skywatcher: if you're choosing a colour for a piece of metal that sticks into the optical path, silver is the worst colour you could choose! It's like they got 98% of the way to building an awesome scope and then just chucked it out there. Fortunately, taking it the rest of the way isn't too hard... Anyway, where was I? This is the Iris, in a good direction for me at the moment. It's off a dual rig, the colour is 70x 2 mins from a 130pds & Canon 550d, and the luminance is 550x 15 seconds from Quattro 150 & asi1600. Pretty pleased with the L data, but it became obvious that I'd let the 130 get well out of collimation 🤦. Hopefully hidden in the processing!
