I am looking into the ZWO 2" 5 position filter wheel. I have not had much luck finding reviews of this product for comparing to other filter wheels. My main concern is the following:
First i would image with multiple filters on the same night
Next, in the morning I need to generate flats for each filter.
I have read somewhere that some of the filter wheels do not position at the exact same location each time.
This would make generating flats frustrating as there would be alignment problems when you go to calibrate.
Anyone have any info on this situation and the product?
