Hi. I have been imaging the same object but with different exposure times. Using the same gain and temperature settings on my 183C. Can all these images be integrated in one go with APP or do I need to process the ones with the same exposure settings separately before trying to combine them in a program such as Photoshop?

Hi Charles @charles-thody,

You can simply integrate them together in APP 😉

In 6) integrate, you can create different integration results if you play with the integration weights 😉 that will have a clear effect when you integrate data of different exposure times. With Star Shape weights you get the sharpest results normally, for instance.

Kind regards,
