DARK FRAMES DIFFERENT BETWEEN SKYPRO AND CCDSOFT

ISSUE

A dark frame taken using SkyPro and applied to a light frame taken by CCDSoft results in a different image than a dark frame taken by CCDSoft, then applied to a light frame taken by CCDSoft.

RESOLUTION

Symptom
============================================================
Dark frames acquired by SkyPro do not work with light frames acquired by CCDSoft

Cause
============================================================
SBIG changed its camera temperature regulation equations. SkyPro uses older equations, CCDSoft uses newer equations. This difference results in different dark frames between the two applications.

Resolution
============================================================
Retake dark frames with CCDSoft.
