My fall astro-imaging project was a 2-panel x 2-panel mosaic of the Pleiades open star cluster in Taurus. I used my standard equipment: StellarVue SVQ100APO refractor (100mm, f/5.8), ZWO 183MM PRO camera, and AstroDon filter set. I collected six hours of image data, per mosaic panel, through the luminance filter.
The image data collected through the red, green and blue filters did not align well with each other. I'll need to re-do that component in the fall. There must be some strategy to collecting image data through each filter such that they align well with each other, like making sure that the telescope is consistently pointed in the same part of the sky per mosaic panel, per filter.
For the time being, I can share the luminance mosaic (full resolution):

What I discovered - and most of you probably already know this - is that there are quite a few distant galaxies in the background. For example:

I invite you to scrutinize the full resolution image for other distant galaxies. I think that I once counted at least ten faint galactic smudges.
Enjoy,
