Aberration in starspikes with Newtonian

Christian VulpescuChristian Vulpescu
edited September 2022 in PixInsight
I use a 10" Newtonian with a ASI 2600 MM Pro and a filterwheel with Astrodon Tru-Balance Gen II RGB,  2", unmounted Filters.
In this picture I got strange aberrations of the star spikes at the brighter stars around Gam Cass. The phenomenon accures in every stacked channel - evan in the narrow band channels, I stacked.
The picture, I made befor of LBN 552 didn't have the problem and I didn`t touch the optic tray between the LBN 552 project and this one of The Ghost of Cassiopeia. I think the scope made a meridium flip during the R, G and B recordings.
This picture was processed with the latest version of Pixinsight.

Can anybody help me with his miracle?

Thank you and CS,

Christian

    Your spikes are solid colors.
    This means you took filtered data at different times... AND that the rotation of the field was different. The camera moved. When you align the images... the star spikes will indeed be rotated and not match.
