Excellent answer - Thank you very much. To me the size and weight only matters in regards to the star tracker. The only issue I have with the Laowa is, that it is almost too small, so that it’s difficult to both fit a few heater and turn the manual focus on the lens at the same time.

Good point regarding the use of heater, I totally agree with you,  that's exactly the reason I replaced my Sony 20 with the Sigma 20 F1.4, it really makes use of heater so easy.
