Hello,

 

I recently took images of the night sky and my camera has quite a lot of Hot Pixels when doing a long exposure.

I recorded Dark Frames with the exact same settings and I want to know: How do I process them?

Is there a way to efficiently remove hotpixels? Does anyone have advice in general?

Hot pixel reduction should be done by the camera before image data is processed.

According to the Photo 1.7.1 announcements (Windows, Mac):

Hot pixel removal is now automatically performed by the Serif Labs engine.

Noise reduction 

Noise reduction and Hot pixel reduction is different functions. Of course, it depends on the camera whether and how it is implemented, but the hot pixel reduction is as you described in the first post (two exposures under the same conditions - same setting and same time), but the reduction is done before the actual image data is processed. Doing it after processing images will not produce such results.
