Dark and Flat subtraction
Posted: Fri Jan 11, 2019 10:25 am
Hi,
I know that I can subtract flats and darks from the light frame so that the stack shows the corrected image, my understanding from the manual is that if I have save individual frames enabled then these frames will also contain the correction as well. Am I misinterpreting this as ideally I would like to save the unadulterated light frame as I use the live stick to see how things are going but actually do my final stacking of the different monochrome channels in APP were I can subtract bias/ flat / flat dark / dark from the original lights and also control the methods used to a greater extent.
At present I run the live stack with out calibrating in flats or darks as I don't want to risk affecting my later processing.
Edited at13:03 to add below
Also just noticed the Calibration Frames post further down that answers the question not sure how I missed it earlier visit to specsavers next I think to add a second question I am not sure how Sharpcap does the Flat and Dark correction in the program would it be possible to have an option to make a selection to say save the un altered light frame before the flat + dark subtraction was carried out for the live stack If this sounds feasible I can feel a feature request coming on
Cheers
Nick
