Below is the script provided by Siril.org to process Seestar images. It was written to support Siril 1.2. Can it be improved given 1.2.4 is currently available? Thanks, Jim

########### PREPROCESSING SCRIPT ###########
#
# Script for Seestar Deep Sky images where
# darks, flats biases are not provided. Only
# lights are needed.
#
# Please, REMOVE all jpg files from the
# directory.
#
# If you find that too many images are discarded
# before stacking, you can increase the value after
# -filter-round= in the seqapplyreg command, line 39
#
# Needs 1 set of RAW images in the working
# directory, within 1 directory:
# lights/
#
# Changelog
# 1.2 : using link instead of convert
# 1.3 : removing -date option: https://discuss.pixls.us/t/error-trying-to-use-seestar-preprocess-script/46400/3
