Don't mean to hijack this thread, but I have both an X-A3 and an X-T2. I was wondering if anyone knows if the X-A3, with it's Bayer sensor, would be an improvement over the X-T2 for astro. Unfortunately, I won't have the opportunity to test this out any time soon, but it would be helpful to know for the next time I do get to go out.

Tom, it's not hard to check the A3.  Take a 2-4 min. ISO 800-1600 dark frame (body cap on in dark room).  Open the file w/ RAW Digger & look at the histogram.  If there is filtering, the histogram will be chopped off or have steps.  A dark frame from the T2 will show you what filtering looks like.  Be sure to turn LENR off.

I'd offer to look at your file but am on the road for couple weeks.
