Samsung NX mini, a Top Infra-Red ILC for $125

.
Here are 2 ways to get a used Samsung NX mini :
- NX-mini Kit w/ 9-27 ED OIS zoom lens + Ext. Flash : ~$150€ = the price of ~3 R72 Filters
- Body Only or with the 9mm ED Pancake lens : ~$100€ = the price of ~2 R72 Filters

The Kit gathers almost Everything interesting from Samsung for ~$150€...
the Ma4NxM adapter and the 17mm f/1.8 are Very Rare...

For the price of 2 / 3 R72, you'll be able to Avoid that R72 Filter, thus the Tripod + High ISO setting :

Exif : NX-mini, 9mm f/3.5 @ f/8, 1/558 sec. ISO 100

Yes, the Q, Q10's sensors are 44.4% More Sensitive :

For beginners, the Samsung NX mini have a lot of advantages :
Samsung-NX-mini-TOP-Infra-Red-ILC

+ NX-mini are easy to find at $100€ or less

+ NX-mini's IR-cut removal is 100% Fully Reversible

+ NX-mini's AF is still 100% Reliable after its IR-cut removal
>> that opens to you the door to Fantastic Hand-Held Terrestrial IR PhotoGraphy -vs-
with the IR-Cut in place + a R72 Filter you're restricted to High-ISO-Tripod :

Best 25+ Infrared Photography ideas on Pinterest | Pink trees, Beautiful nature spring

+ NX-mini's Wider Sensor mounted on a 800 mm will cover Veil Nebula's 2 parts :

+ NX-mini's Bigger Pixels are Far Less Demanding from Atmosphere Stability :

+ NX-mini's Bigger Pixels are Far Less Demanding on Eq-Mount-Precision :
Pentax Q, Q10, most Sensitive sensor ILC

+ NX-mini can hold 240 seconds Bulb Exposures !

+ NX-mini's L.E.N.R. is Fully Cancelable !

+ NX-mini's Huge Battery will last a Winter-Night long !

+ NX-mini's Wired Remote Controlers are easy to find at $25€ or less
... SR2NX02 compatibles

+ I'll add one page : How to add a T2-Mount-Thread M-42x0.75 for $25€ on your NX-mini
... this is crucial because Sam's MA4NXM Adapters are out of stock...

Here is the last Astrophotography I posted from that little Costless Camera.
it's not as sharp as I hoped : the 2nd Night, I got Huge Turbulence
Fine Colors, No Dark-frames, nor Bias-Maps subtracted :

Much Noisy, 13 subs instead of 24, but Sharp !

You'll get better pics with yours...

It's too bad samsung left this line abandoned and more so the parent line NX.

And just at the moment they reached the Top of the Best possible Image Quality !
That was an incredible surprise for everyone...

Sometimes... I think that Pentax, after their K-5's Big Success...
should have resumed its sensor supplies from Samsung
when their NX1 and NX500 reached DxoMark's top !

Instead of being forced by Nikon to settle for old Sony sensors...
... the Pentax K-1's sensor is the one of the D800E !
Imagine a K-1 w/ D850 sensor + Pixel-Shift...

Don't you think so ?

My last AstroPhoto : M-51 Whirlpool Galaxy
the Samsung NX mini mounted on a Sky-Watcher 254/1200 Newtonian
30 subs of 4 minutes each guided by Phd with a ToUcam

And the NX mini could achieve even Better Image Quality :
- here is a lot of Fixed Pattern Noise at 25 from the Vertical direction !
It couldn't be a problem from the imx183 sensor,
raw image noise due to electrical waves ?
Here is a 2000*2000 pixel M-51 :

It was also the very first time I used the NX mini under the ~Full Moon...
... and Without the Baader SkyGlow Filter, removed for a Q10 ISO 800 shooting !
So the Sky Background is way brighter than NX mini usual...

Here still the same 30 subs without any filter...

Hi All Pentaxians !

... or maybe the full Moonlight + the fact I did not mount the SkyGlow filter ?

Yesterday, the sky was filling with clouds as soon as the night became dark for Astro...
... I stacked the 29 subs remaining (1 trashed ) in Kappa-Sigma mode,
which is designed to minimise Out of Range pixels Effect

The result is less noisy, so less NR needed

For now, it's the best... isn't it ?

Samsung NX mini, a Top Infra-Red Astro-ILC for ~$125~

.
The next Astro-Photography I built with the NX-mini was M-16...
= Eagle Nebula from 30 Raw files without Dark-Frames nor Bias-Maps
( I never need to subtract Dark-Frames nor Bias-Maps from the NX-mini Raw files ! )
.

.
The whole Story is explained here :
Maxi Astro (Ciel Profond) au NX mini...
.
This year, I submitted 4 Astro-Photographies to DPR Challenges :

-1. Messier 27 this Spring... was 6th in the "Samsung Challenge" :
Samsung NX mini, Top Infra-Red ILC for $125, #1
-> exactly this one !

-2. Messier 51 this Summer... was 4th in the "Surprise Me !" Challenge :
Samsung NX mini, Top Infra-Red ILC for $125, #6
-> a sister of that one, a desaturated and upside-down version !

-3. Messier 51 again... was 7th in the "PURPLE challenge" :
Samsung NX mini, Top Infra-Red ILC for $125, #7
-> that one, but slightly desaturated !

-4. Messier 16 a few days ago... was 11th in the "red challenge"
-> the one displayed in this Post !

Finally, not so bad for Astro-Photographies that are rather "Off-Topic" on Non-Astro Challenges !

For you that want to give the NX-mini a try in Astro-Photography... but...
... do not own or could not find a MA4NXM Adapter to connect the NX-mini to M48 / M42 T2 Mounts...
I find a very simple solution by Adding a M48 Mount Thread to the NX-mini as is !
+ another simple way to lower the M48 Mount Thread to M42,
So one can use the NX-mini with every instrument !

Samsung-NX-mini-M48-or-M42-Mount-Adapter

the NX-mini has so High Performances in (Very-) Low-Light, is so easy to upgrade to Full-Spectrum :

Samsung-NX-mini-TOP-Infra-Red-ILC

Sincerely hope this will help you to take an easy plunge for Astro-Photography !
( in Landscape IR-Photography, the NX mini will be a winner too )

Messier-20, Trifid Nebula = 50 Millions of Billions of kilometers away from Earth !
30 .SRW Raw-files stacked with DeepSkyStacker & finish Elements 3.
This is the Most difficult Astro-Photo built during the summer
- M-20 is only ~22 degrees over the horizon, some shots ending in the trees...
- that also means Maximum Light Pollution + Max Turbulence effects !
- Ambient Temp was ~25C, had to Not over-use the LiveView...

Right Click + View image + Zoom to enlarge :

... Coming soon ?...
M-8, Lagoon Nebula is too big to fit inside the 1" frame
... then, I will try to build a fine picture of M-17, Omega Nebula...
Next Year 2020 guys, last time was way too dim :
M 17 - Test Pentax K-5 iso 80 = 4 x 12 min - Pollut Lumi Maxi - AstronoMike.net

Ladies, Gentlemen and Moon-Maids...
... here is the Image Quality one can get with a 1" BSI sensor !

I was somewhat helped by the Atmospheric Conditions : hazy and quiet...
- but the Colors - especially the Red and Blue - suffered a little
I couldn't get the amazing colors of the page top M27

The result is so detailed that I uploaded it in ~3000 x ~2000 pixels
-> you can watch the 3000 Pixels Wide Picture here :
Maxi Astro (Ciel Profond) au NX mini...
and also there :
M27, seen as if you were close : Digital Photography Review

= 30 .SRW Stacked, then Levels Push w/ Elements3
Right Click + View Image + F11 to watch...
the half-size preview of M27
.

Enjoy !!
