This image of m13 was taken using the Atik mono 460ex. But the important thing to note is that it was done using a Beta Release of the Infinity SW that opens the Infinity SW to the 400 series of Atik cameras. I was very pleased with the SW as it offers all the same advantages that were realized using the Infinity but doing it with a camera with a larger sensor, more pixels and cooling.
I used an Explore Scientific 102ed which is a 102mm objective and 714mm focal length. Also used the Explore Scientific field flattener.
I am very pleased with this experience.
The image consisted of a stack of 25 for a total time of 750 sec. Was touched up a bit in Lightroom/Photoshop and light cropping.
