I didn't had the time to challenge the GFX100s vs the Night Sky. But I've found its results were perfect in
the Christmas and New Year's Day testing I've shot with it.
The linked page can be pixel peeped at 200% without hesitating. All the Photos taken have been shot Hand-Held and - despite in JPEG quality -
they have been Underexposed of at least 1 Ev to Preserve Highlights. Real Scenes Light Values around 4,5~5 Ev (Sodium Vapor lamps) -vs- EXIF Light Values
are 5,7~6 Ev:

the Fuji Gfx100II is much better in very Low Light conditions than the CCD based Astro Professional cameras from 1990 -2014, despite they were worth
hundreds of-thousands of Dollars. The GFX100II's CMOS sensor runs 10 times cooler than those big CCDs. Then, it has little need for a sophisticated Cooling
System. BSI Technology plus Micro Lenses ensure similar Yields of Electrons generated per incident Photons (QE), at least in the Visible Spectrum. Dark Current
levels have been divided by thousands v CCD. Read Noise and Electronic Noise have been considerably reduced since CCD times. CMOS have Noise Cancelation at
pixel level and Digitize their Signal directly on chip so that it can be Pushed much more than the one from CCDs :

From '90 to 2010, 20 years of Electronic Revolution :
1990s CCD sensor compared to 2010s CMOS (BSI) one
:
Signal is now Cleaned + Digitized " on chip " = the Exmor Bonus !
In addition, to avoid overheating the Gfx100II, it can record its Raw files via USB 3.2-gen2 to an External SSD, even at very high frame rates.
In-case, you have an Optional Cooling Fan to mount at the Gfx100II's back. Good News: you no longer have to wait until Christmas - New Year's Days to keep the
Magnificent Colors of Magical Nights ! What are you waiting for to challenge long exposure DSO Astro Photography w/ hundreds of Short exposures
of 1 second ?
Then, no longer need for :
-1. Super rigid EQuatorial Mount.
-2. Very precise Alignment to the Polar Star.
-3. Very precise and finely Calibrated Guiding System.
As long as you can track, even manually, just to keep the Deep Sky object target into the camera's field of view. Come on. I'm going to help you take the
plunge by showing you what you could already achieve with long exposures and Very Little Equipment. Pentax K-5, Q10 and Samsung NX-mini on Skywatcher
200/1000, then 254/1200 on a Black HEQ5 Mount. A Goto Kit later and a WebCam on the finderscope for Guiding via PhD. Knowing that by limiting your
exposures to ~1 second you will easily get images 4 times Sharper than mine ! Using a Gfx100, you'll easily get better Colors than mine. One Bad, GFXx
can't record cropped RAF's ROI. Couldn't this be done by SW to FITS files: write to FITS files the ROI from RAFs inside a FF, APSH/c, 4/3, 1"
delimiter you'll move over the full MFc ?
ROI: acronym for Region of Interest, cropping tool in CMos Astro Cams drivers.

Sony FF, Best of the rest. Red Logo lacks Light. Click to Enlarge
Black on White or reversed letters are well readable in both crops. Green Leaves also are well rendered in the crops. But the Black on Red letters are
very different. While the "THE OLD BREWERY, Samuel Smith, TADCASTER" Red Logo is ok with readable "The Old, Tadcaster" on the Fuji crop - it's
Totally Blurred by Heavy Noise in the Sony crop, why such a Result ? Apart from Gfx50-100, other FF-MF cameras show very Poor results in Black on Red.
It's Not a Pixels question. They benefit from same design and 3,76µm pitch in both cameras. More, even old 51 MPix Gfx50x render the Black on Red
Logo way better than Sony. Plus, It's Not a Sensor question. Even Phase1 IQ3 100MPx shows nothing more than Noise with the same MFc imx461. I
think this may well be due to the Race for the highest ISO Numbers ! This could also explain why Phase1 has suddenly found necessary to release
TriChromatic new Models with a much More Selective Bayer filter in front
of their sensors. Please, guess when this happened, just 1 year after the release of-the Fuji Gfx50s (MFc imx161 FSI 2014) with better Red Results than the
A7r5.
MFc: acronym for Medium Format crop, as ~44x33mm sensor (55mm diagonal) instead of MF, as ~53x40mm sensor (67mm diagonal).

This is a very important specification for ~1 second Exposure astrophotography. Especially for Red nebulae such as IC5146, N2237 which
are nearly invisible in big city Atmosphere with Light Polluted Bortle 9 sky. More so here at sea side !

I didn't had the time to challenge the Gfx100s vs the Night Sky,
but I've found its Red results were perfect in the New Year's Day and Christmas testing
I've done with it, the linked page can be pixel peeped at 200% without hesitating.
The fact that the Gfx family all have a Bayer CFA inside is also a very important specification for ~one second Exposure Astrophotography.
Then, you'll have the possibility to challenge the lot of Demosaicing Algorithm available for the Bayer cameras, for example, with
Deep Sky Stacker. Or, try NO Demosaicing with the Super Pixel Algorithm
that will divide the total job time by 2 or 3 but delivers you Superb Results without re-inventing 2 colors on 3 for each pixel location. In this case,
the final image size will, of course, be of 26 MPx instead of 102 MPx.
CFA: acronym for Color Filter Array, 'GBRG' mosaic over the sensor.
Let's compare the Gfx to a Pentax K3 Mono which is for sale at ~2500 Euro:
-1st. You can downsample Gfx100's images from 102 Mpx down to 26 Mpx
Giving the Gfx a big Advantage over the K3 for LowLight Noise, Sharpness.
And just in case, of course you'll get a huge latitude to Crop inside 102 Mpx.
-2nd. Having Color informations in files, you can still Play w/ G, O, R, Y filters
At Shooting time, but also at Processing time, to adjust Relative Tone, in the
clouds, in the sky, in the grass, in the foliages, etc. Huge Advantage for B/W.
G,O,R,Y, for Green, Orange, Red, Yellow Filters used for B/W Photography.
-3rd. The Pentax K3 Mono still doesn't even have just a "Tilting" LCD, a real
shame today. You'll have to practice Extreme Yoga for Astro, Macro-Photo.
That was barely acceptable for the Pentax K-5 in 2010, but now in 2023...
-4th. A "Tilting" LCD is also a way for the camera to evacuate Heat through
the back of the device. This way, lowering Noise, Hot Pixels, etc, in pictures.
See-what Sigma have done at the back of their mini fpL to get rid of Heat.
First, a direct Go to some of these MF sensored Astro Cooled Cameras :
Direct links to some of the
Astro Cooled MF Cameras at the end of this §
The 1st Difference is the Huge Selling Price of these Big Cooled Cameras. Worse, you are Not ready to find a used one at the price of a used Gfx100x.
The 2nd Bonus is that buying a Gfx100x, you'll also take Cityscapes, Macro, Landscapes, Portraits, Still Lives, Street Photos, etc, where the Fujis Excel.
The 3rd Bonus is, even for Astro-Photography, you can count on a Reliable AutoFocus on a Mid-Bright Star each time you are using a Fujifilm GF lens :
Full Set of Fuji GF lenses : Diagonal, Height and Width equivalent FL in
135 format + D H w AFoV for 2 long ones
Works also for some Adapted AF Lenses, depending on the Adapter used.
4th. The Excellent Reliability over the time of a " Made in Japan " High-End Camera, is way better to me than the one of any fast made chinese device.
5th, the CFA of the Big Astro Cameras is certainly Optimized for High-Gains -versus Not for HQ result w/ Hi-Fi Colors as Fuji is. Please read the § above.
6th, all the Fujifilm Gfx100 cameras are able to work in 100% total autonomy -versus Astro-Cams all do need a Computer AND a Power Supply to Work.
Power Supply is 12V @3A~5A DC specification as recommended by Zwo.
7th, Gfx100II can externalize its Warmfull Writing process to a discrete SSD.
It can record Cold Video, this is Thousands of sub-frames to stack together.
8th. No Guiding, No PC for Short Exposure duration Astro-Photo w/ Formula :
ShutterSpeed#sec = ((Aperture*35)+(PixelSize#µm*30)) / FocalLength#mm
- Gfx100x 1 sec. Max Exposure, GF250 @f/4 don't need a PC for Guiding,
((f/4*35)+(3.76µm*30)) / 250mmFL = 1sec. Max Exposure w/o Guiding.
GFX100S+SII+II MF-Cameras' most differentiating Specs :

The GFX50SII with its 2014 FSI CMos sensor is not the best for Long Exposure
in Low Light. There's purple Amp-Glow at the bottom of its 1/10sec dark frames :
Amp Glow in Fujifilm GFX 50S Mark I and II - Jim Kasson
Its ContrastDetect only AutoFocus is on the Hesitating and Slow side, especially
in Low-Light conditions. So, I shouldn't recommand it here, but I should in a page
about Events, Landscapes, Portraits, etc, with good lighting.
The Big and Heavy GFX100 is the Precision tool for Studio work, Art and Object
reproduction, Macro, Negative and Slide Film digitizing, Portraits, Still Lifes, etc.

October 2023's price was down at 5200 Euro.
GFX100II's size and weight are just in between the 'GFX100' 2 previous MILCs.
It's able to record up to 8K30p video at 720Mbps data rate on a CFExpress 'B'.
You could even think about Astro "Lucky Imaging" recorded on an External SSD.
