Astrofotografie mit Pentaxen - RAW direkt aus der Kamera bevorzugen

[Gast_308519]

Hier ein kleiner Hinweis:

It appears that accessing the in-memory raw image data of the camera via PC control software offers data at a less processed state and - most importantly - the image pixel mean intensity is not shifted to zero level.
...
dark frames exhibit a nice gaussian intensity distribution

The bottom line of this means: if you are going for deep-sky astrophotography and stacking of many long exposures (or otherwise need the unaltered noise distribution of raw image data) you should access in-camera in-memory images via PC control software. That's it!

M.a.W.:
Für solche Anwendungen die RAW-Daten mittels pktriggercord aus der Kamera ziehen, anstelle diejenigen von den SD-Karte zu nehmen.
