Hello, I recently got the Takahashi Fs60Q but noticed it had some chomatic abberation around some stars.  This was from my shot of the pleiades.  Is there any way to remove it, or am I just stuck with it.  I know the 60CB has CA, but the Q module is supposed to remove it.

 

 

Thanks, Sullivan

take a screenshot (print screen function) of a zoomed in portion of your image, showing what you describe about the stars, paste it and crop it in the Paint program, save and the file size should be small enough to fit in the thread

Are you talking displacement of colors, or halos?  The latter might be for really bright stars with high UV contribution (like the plejades....), as any refracting telescope will have issues at/below 400nm.  Something like the Astronomik L3 UV/IR block filter would help then.
