Description

best 800 frames out of ~35000. Aligned and stacked with Siril, but since Siril does not support planetary alignment with rotation and the Alt-Az mount introduces some, frames have been pre-analyzed using the Rigid Align plug-in of Fiji (Imagej). The extracted angles have been inserted into Siril's .seq text file in the "R1 section, so that when running "Apply existing registration" Siril has also used that rotational information.
This is a useful technique for other type of objects such as NGC7009 that lack stars in the narrow FOV of a long focal length scope.
