Touptek ATR183M
The camera with the powerful Sony IMX183 sensor allows astrophotography on a very high level. This modern sensor can be used for many areas of astrophotography. The 2.4 µm pixels provide an extremely high resolution, which makes very good use of the imaging quality of fast telescopes of very high quality.
Another advantage is the sensational light sensitivity. The QE of 84% by the BACK ILLUMINATION technology and the very low amplifier glow make the camera not only very suitable for imaging solar system objects, but also suitable for deep sky astrophotography.
Due to the absence of the Bayer mask, the monochrome camera is more sensitive than the color version. With L-RGB filters, you can nonetheless create fascinating color images of the universe. We recommend bW cameras especially for light-polluted skies, for example close to towns. With suitable filters, like nebula filters, you can select the light of deep-sky objects very well. Suitable filter wheels can be found in the accessories section.

Back-illumination technology:
Sony´s back-illuminated CMOS imaging sensor improves sensitivity and noise reduction - key factors in improving image quality - by changing the basic pixel structure from front- to back-illuminated. The advantages of CMOS image sensors, such as low power consumption and high operating speed, have been retained.
The back illumination improves the light acquisition and increases the amount of light at the same time. This makes significantly shorter exposure times possible and leads to an improved quantum efficiency of 84%.
Sony has developed a unique photodiode structure and on-chip lens optimized for backside-exposed structures, this results in higher sensitivity and lower random noise without light by reducing noise, dark current and defective pixels compared to the conventional front-side-illuminated structure.
Connection to correctors with M48 thread and 55 mm working distance with filter change
Most coma correctors or field flatteners for refractors have 55 mm working distance and an M48x0.75 thread on the camera side. Here you will find an interesting suggestion for the connection. The camera has a back focus of 17.5 mm from the T2 female thread. The adapters are from the camera to the corrector:
1. TSFSLM48T2 - filter drawer with T2 connection on the camera side and M48 thread on the telescope side.
2. TSVF220 - 20 mm M48 extension.
Total 55.5 mm flange focal distance - the 0.5 mm compensates well for the glass travel of the filter - spot landing!!!
