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.

Technical Data
Two stage TEC cooling System ans Anti-dew technology
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!!!
