ATR585C

la cámara es un sueño, sólida, pero ligera, robusta, silenciosa. Aquí en Bonaire Cloudy Nights Observatory está montada en un telescopio de 102mm Ed. La primera fotografía fue excelente, como prueba fotografiamos diferentes estrellas y mas tarde la gran nebulosa de Orión. una gran gama de colores y su temperatura bien sostenida.
usamos APT como programa de manejo y no tuvimos problemas, en unos días haré otras pruebas y también las primeras sesiones de astrofotografía en sí.
Esperamos poder publicar con ustedes esas fotografías como muestra para otros de su gran calidad y capacidad.
Aquí en la isla de Bonaire, somos el único Observatory, la idea es crecer y tener un equipo mejor.

Very happy so far with the one session of ngc300

The sensor in this camera is really decent modern sensor, and although it's very small, the 16-bit HDR mode makes for a pleasant switch from a DSLR. Especially considering how low the price is compared to other manufacturers (often even cheaper than used ones) this is a no brainer for a first astro cam. Shipping to Poland was insanely quick (5 days over the weekend with FedEx Express) and of course free, with no additional customs fee.

UPDATE 18.07.2024:
After a positive reaction from Touptek and their guarantee to release a firmware update that fixes all the issues they finally gave me the new version (4.36) to test and analyse. Well, what can I say? The results are mindblowing! The engineering department could increase the dynamic range even further than before. We are talking about 15.56 stops of dynamic range with 0,6 electrons read noise and 16Bit, which is astonishing.

Touptek kept his promise and delivered a fix in record time. Thats the reason to increase my rating from 2 to 4 stars. My next step will be testing this camera under the stars. If it can deliver the performance the whole night in a stable manner, the rating will be 5 stars and my absolute recommendation.

I posted the new sharpcap analysis in the review. You can have a look.

Original review:
I was very excited to buy this camera because it is the newest sensor technology from Sony with dual gain ClearHDR, which captures a picture 16Bit with over 14 stops of dynamic range.

Its finish is high quality and the fan is extremely silent. No driver or compatibility problems, everything is fine. Until I did a sensor analysis. Touptek and some youtubers advertise this camera with 16Bit, 0,6 electrons read noise and over 14 stops dynamic range in HDR mode. You can read it in the official Touptek manual.

My sensor could only provide 14 Bit with almost double the read noise and a maximum of 14 stops DR. I thought I was wrong and wrote the technical engineering departement of Touptek via Mail. They verified my assumptions because of HDR problems in earlier firmware they had to release an update (Firmware 4.35) which locks you out at 14Bit and reduced HDR performance to guarantee stable sensor performance.

To be honest this information is disappointing to me because I bought this camera especially for the HDR mode @16Bit. Touptek does not provide a bulletin on their shop website or manual which describes the reduced performance in the current firmware.

I dont know if this sensor will get another update in the future which opens up the HDR mode again. And if yes, when it will be released.

I am thinking about refunding because of false advertising. I attached my sensor analysis result which the techincal dep. of Touptek also received from me.
