Interesting review.
I went for the ASI 183MM for solar imaging (SM60DS/ ED80/ x2.5 PM) and found "major issues" - ZWO accepted it back and I eventually went for the ASI 1600MM which has worked well for me.
From the ZWO site:
High Speed
Fast FPS can be used in solar(white light) and lunar imaging, as well as for live viewing/EAA.The high speed readout may also be used for real-time focusing, true lucky imaging of double stars and other small objects, planetary imaging of the major planets in the solar system, and much more.
Notice: depends on user’s feedback, this IMX183 sensor has grid pattern noise when do Ha solar imaging, please take flat frame for calibration(out of focus or add a barlow lens to take flat frames). We recommend our ASI1600/ASI174 mono camera for Ha solar imaging.
