members trying my first go at processing in my newishly acquired nebulosity
looked at a couple of tutes and put them to use and this dialogue came up
"you must specify at least one pre processing file, otherwise not much processing is going is there?" ha ha
will neb process just lights without the others?
pat
The preprocessing is to calibrate the lights with darks, flats, bias etc, processing lights without these does nothing, thats what it is telling you.
If you don't want to calibrate go straight to debayer if it is osc or normalise if it is mono.
