Fuji X-T100, Best Astro Camera but higher Long Exposure Noise
1

As I've demonstrated in other posts, most Fuji cameras have under the hood RAW NR for exposures longer that 5 sec. The filtering mangles star shape & alters or removes star colors. Many - most - all? cameras using Sony sensors seem to do some form of this. Recently, a user demonstrated even the GFX-50S has filtering which eats little black holes in stars.

Not the X-T100. Here's a comparison using the exact same region of stars w/ all images developed the same. Its like getting a much sharper lens.

The advantage of the unfiltered X-T100 for star images also gives a downside - higher long exposure noise. W/ good NR software, much of this problem can be removed. Here's untreated & treated example of the X-T100 compared to the filtered X-T3. You'll have to peek to see the noise.

FWIW, one reason modern Sony sensor cameras apply NR to RAW for long exposures is to hide the effects of the PDAF array on the sensor noise. For that reason, I'd expect the new X-T200 w/ 425 PDAF sensors to filter RAW like the X-trans cameras.
