ZWO ASI294 MONO CMOS Camera for astrophotography
ASI cameras stand for very good workmanship and have modern CMOS sensors installed. This camera uses the state-of-the-art "back-illuminated" Sony IMX492 sensor.

The 4.6 µm pixels of the ZWO ASI294MC make this camera an all-rounder with maximum sensitivity for short exposure times. The resolution is 4144 x 2622 pixels.

You can increase the resolution by using the camera in "unlocked mode". Then 2.3-µm pixels are available, with a resolution of 8288 x 5644 pixels.

Advantages and features of the ASI 294MM mono camera:
USB 3.0 for a fast download - can also be used with USB 2.0
Sensitive CMOS sensor with 23.2 mm diagonal
Good resolution due to 4.6 µm pixel or extreme resolution due to 2.3 µm pixel
Distance from T2 connection thread (female)to camera sensor: 17.5 mm
Comes with AR protection window - full transmission also in IR. If infrared should be blocked, an IR-cut filter is necessary.
Very high sensitivity - QE more than 75% - ideal astronomy camera for dim objects
14bit ADC
HCG mode - if gain is higher than 120 (12 dB), read noise is reduced below 2e - result: low-noise images despite extremely high sensitivity.
Full well capacity locked 63700e - even bright stars do not burn out anymore, you get a better signal-to-noise ratio.
Adaptions, cables, ... are included in the scope of delivery


Application ranges of the camera:
Solar, lunar and planetary images: extremely short exposure times (due to high sensitivity) freeze the seeing. Through the high resolution of the sensor, many details can be reproduced even at shorter focal length. Video astronomy is also possible.
Deep-sky images (nebulae and galaxies): Due to the high sensitivity, nebulae and galaxies are captured after only a few seconds. Despite the camera is uncooled, it is possible to obtain low-noise images with high resolution. By increasing gain (like the ISO setting of DSLR cameras), you can reduce exposure times below 30 seconds. Effects from seeing or inaccuracies of the drive are eliminated.


Connection to correctors with 55 mm working distance, M48 connection and filter change
For the photography of nebulae and galaxies, a corrector is required for most telescopes. This allows you to position the camera at the correct distance and also gives you the ability to change filters, which is important for L-RGB photography. The articles are linked in the accessories section.
ASI294MM flange focal distance 17.5 mm (distance from T2 thread to sensor)
TSFSLT2 filter drawer - height 18 mm
TSM48-T2L extension to M48 thread - height 6 mm
Bahyp14 M48 extension with 14 mm length


This will give you the perfect spacing. The 0.5 mm more compensates for the thickness of the filter.

Question:
How to mount the camera on a tripod or dovetail bar?

Answer from Teleskop-Service:
In the center of the back of the body, there is a female 1.25" photo thread. This allows you to mount the camera on a tripod or dovetail bar (possibly via an L-bracket for binoculars):

"Die monochrome Kamera ist perfekt für Sonnenbeobachtung mit Ha-Filtern, deutlich bessere Ergebnisse als mit RGB Kamera."
