I enjoyed looking at your website.

Can you please tell me how you image with the following setups and NOT get severe vignetting:

1) Tak FS60C + SXV-M25C camera
2) Tak Sky90 + SXV-M25C camera

What are the exact components and order in which they are added to the telescope. If you use any spacers, what is the length of the spacer?
(as example: telescope + focal reducer + spacer + camera)

You're already very good and I'm sure you'll post even better work in the future.

if you have astroart, there is an easy way to process M25 color shots.
You have to download the plugin SVX color from the astroart site, process
the image through this plugin (I use offset=X on) or better through the option
batch for multiple images. Yoy will obtain images with a strong blue dominant.
After this you select two stars from one of the images and go to "preprocessing"
you select "add" deselect "confirm each image" and select "autoprocessing" and
then you go "OK" When the process is finished you go to color balance and make
the skyground neutral so that the natural color will appear on the subject.
I learned this procedure from the inventor of Astroart.
Good luck
