Thanks for the advice everyone.
Has anyone used the Takahashi Sky 90 for imaging?
How is the color in that scope?
If I do only narrowband imaging, should I be concerned about color aberrations?
Planning to use an APS-C sensor. Will there be vignetting? I am trying to avoid flats.

Hello everybody.
I am a newbie, started astronomy 1 year ago and currently looking for a astrophotography scope.
Do the good bros here have any advice? Budget of about $2k, prefer small refractor.

Thanx.
