| My Site to improve (DIY) your Pentax / Samsung "Astro-IR-camera" !  Originally posted by barondla  Yes, it is visible now geo444. Nice looking start. Thanks, barondla Originally posted by Binth These are impressive results ! I may need to get my Q out and see what can be done.  Yes, impressive 2 ways verified numbers for these Pentaxung cameras...  Sorry I was so loooong for the page #2... but we had a Very Very Warm Endless 3-Weeks !  Early morning at 27°C... Late evening at 30°C... very hard to sleep few moments... Totally unthinkable from my North Celtic origin ~17°C Max Summer ! I tried AstroPhotos, my HEQ5's Electronics shut off... My old PC-XP had overheat problems too : Unable to find the photos I took 3, 5, 7 years ago... So I decided to begin with the Most Recent ILC I dealt with : the Samsung NX mini ! Thus, I downloaded the 2 Main Pictures I posted on forums for this ILC... So here is the Samsung NX-mini IR-Cut Filter Removal page just uploaded : http://mecastronics.free.fr/SamsungNXminiTOP.html NX-mini is Top-Camera + Pro-Sensor... ~$150, unbelievable ! You found something wrong, incomplete, contradictory, don't hesitate to mail it to me http://mecastronics.free.fr/ Last edited by geo444; 08-20-2018 at 12:52 PM. | |

| My Site to improve (DIY) your PentaxSung "Astro-IR-camera" ! Originally posted by kayakfari Hi geo444, great astro work with your Q10 ! Thank you very much KayakFari ! [humor]  Did you see (page-2) the Q10 succeeded with Messier-57 in Lucky-Imaging Mode ? - Lucky-imaging Q10 Mode was 1 or 2 sec Exposures @ ISO 6400 - Q10 did preserve M57's whole set of RastaFari Colors : M57's RastaFari full Color set from special Super-Pixel Mode M57's RastaFari full Color set from standard Bilinear Interpolation RastaFari flag : Red-Yellow-Green [/humor] Originally posted by kayakfari I am also interested in removing the IR cut filter over the Q sensor. In my case I'd like the extra spectral sensitivity and need the room to mount a very short back focus fish-eye lens, but haven't been able to see how to easily remove it. If you achieve this, please let us know ! I did remove its IR-cut filter when I shot IC-5146 Pentax Q10 succeeded with IC-5146 = Invisible Nebula 30 sec. exposure @ ISO 1600, I couldn't see anything but Stars... Even after 56 x 30 sec. stacked, one can hardly guess the Cocoon Nebula  This was ~4 years ago, the How-To is archived on my old PC-XP : My previous post just above but as it's a very important Modification for Astro-Photo, I'll add a detailed full page on my site ASAP ! (weather back down to usual T°C next saturday) Originally posted by kayakfari I disassembled mine, you can see here (along with exploded diagrams): Pentax Q disassembly and LCD repair – replacement operation. | kayakfari ( kayak .. far .. i ) Regards !

I'm not sure I understand, you are not able to access my site? You shouldn't have any trouble accessing a wordpress.com site unless your local provider is blocking it for some reason? I'm really curious how you removed the IR filter? Is it just glued on, and you pried it off? I didn't want to force it since it's attached to the SR unit! You've done some really phenomenal work with the Q continuum my friend! | |

A while back I saw a youtube video where the guy roughly cut the filter out of the sensor shield ! This left the shield structure. Meant to go back and check it out. Can't find it now. You shouldn't bother about the Q IR-filter, I'll write a page as detailed as I already did... ... just a few days to complete the Q10 Firmware Page... and... I'm in !

| What Sensor in the NANO1 ? Originally posted by barondla Geo444 did you see these new tiny sensor astro cams ? They have a smaller sensor than the original Q, if the mentioned 7.2 crop calculation is correct... Yes, I did some research about their Sensor... but couldn't find any infos ? Originally posted by barondla ... Reading the comments is illuminating. Some have no idea why a small sensor is useful in astrophotography. A shame.

| About what Sensor inside the NANO1 ? Originally posted by barondla Geo444 no idea about the sensor. Didn't think any camera or phone had a smaller sensor than original Q. The comments by some readers were depressing... Products Line up for Camera Image Sensor for Camera | Sony Semiconductor Solutions Corporation an 1/3" or an 1/2.5" Sensor ? Now you know the way to discover What Sensor inside this cam. Pentax Q for astrophotography beginner? - Page 3 - PentaxForums.com you just have to Download its FirmWare... Relative Area of Astro-Cams and Cameras Sensors : 1/3" is a little more than half a 1/2.3" (Q, Q10) 1/3" is a little less than half a 1/1.7" (Q7) | |
