HeliconFocus:
When combining images, HF works best when the image slices in the selection list are in the correct order and same orientation. If they are not, the blending may not work. Auto loading the set from Helicon Remote reduces this risk
Flickering lights will cause slices to vary in brightness. HeliconFocus will try and 'make it work' but the better way is to let the lights warm up for 3 min. before shooting a stack, or replace the bulb.
