Deep Sky Stacker

[Neil]

Hi everyone, hope someone can help with this problem

Downloaded the latest version of DSS 4.2.6 a couple of weeks ago, was working fine till suddenly I loaded files( lum, flats and darks) went through the steps up to registering checked pictures, dssstacker comes up with error message unable to read dark and lum files because they are " read only" however they are not and never have been??:help:

Neil,
Try just loading your light frame subs only and see if you can stack
Make sure you check your Star detection threshold, adjust down to 5% or lower and ensure DSS is reading more than say 10 stars
If darks and flats etc are not the same frame size, file type and bit etc.. as your lights DSS won’t stack them together.
Usually DSS won’t stack due to not enough stars to use as reference and alignment
See how you go
Hopefully others can pitch for suggestions
