ZWO ASI174 Mini - 1.25 "Autoguider and Mono Astro Camera - Chip D = 13.4mm

This astro camera and autoguider offers sensational sensitivity, a state-of-the-art sensor, all in an ultra-compact package no bigger than a 1.25 "eyepiece.
Sony's MONO CMOS sensor IMX174LLJ with a QE of approximately 77% for highest sensitivity.

♦ Pixel size 5.86 μm - so the camera is suitable for almost all telescopes, both for recording and for tracking.

♦ Sensor size: 11.34 mm x 7.13 mm - so you have a large field and always find a suitable Leitstern.

♦ The high sensitivity and the extremely low-noise CMOS sensor enable short exposure times. Cooling is no longer necessary. You can use the ASI174 Mini very well as a recording camera.

♦ Practical 1.25 "housing - put the camera like an eyepiece in the tail pipe, the telescope or the off-axis guider.

♦ Just 60 grams, a true lightweight and no bigger than a 1.25 "eyepiece.

♦ Extensive scope of delivery: Protective cap, instructions, CD-ROM, 2x USB cable, ST4 autoguiding cable, filter ring and 1.25 "extension sleeve.

ZW Optical ASI174 Mono ultra-compact astro camera and autoguider
The ASI174 is the ultimate autoguider and much more. The modern Sony IMX174LLJ MONO sensor impresses with an outstanding QE of about 77%. This high sensitivity, the moderate 5.86-μm pixels and the large sensor area of ​​11.3 x 5.86 mm make this camera very interesting for astrophotography.

The advantages of the ASI174 Mini as an astro camera

♦ High sensitivity sensor connected with high resolution for ultimate moon and planet photos.
♦ Large sensor surface and maximum sensitivity for the photography of nebulae and galaxies. Due to the excellent noise behavior, very short exposure times up to "Lucky Imaging" are possible. Cooling is no longer necessary.
♦ The camera fits into any 1.25 "eyepiece, clamp the camera like an eyepiece, focus and start astrophotography.
♦ The camera is equipped with a clear glass filter that is transparent even in the infrared. This makes exciting infrared photography possible.

The advantages of the ASI174 Mini as an autoguider

♦ You will always find a guiding star, even with off-axis guiding - guaranteed!
♦ The handy 1.25 "case makes it easy to adapt. Plug the camera into the 1.25" recording - focus and get started.
♦ Only 8.5 mm working distance from the leading edge to the chip - so you can focus on even short distances.
♦ With only 60 grams of weight, the focuser is hardly loaded.
♦ ST4 cable and ST4 port are of course included. Connect the camera directly to the autoguiding port of the mount.

The autoguider software is not included. The camera is suitable for PHD Guiding, Guidedog, Metaguide, Guidemaster (freeware) or AstroArt, MaxIm DL (paid).

A tip: With ASIAIR, the ASI174Mini and your smartphone turn into a fine autoguider, which also works without a computer, with higher sensitivity and resolution than the previous "stand-alone" autoguiders ... for really small money - just recalculate and compare.

Spectral sensitivity

The sensor not only convinces with high sensitivity, but also with a wide range. The sensitivity remains high deep into the infrared. This means more stars for guiding and the exciting field of infrared photography (Venus, Mars ...) becomes possible.



So compact is the ASI174 MINI camera:

Compared to other astro cameras, the ASI174 Mini has smaller dimensions, less weight, and it reaches the focal point in the same place as an eyepiece.



What is included?

The packaging of the ASI Mini Camera has all the necessary cables, drivers, adapters and also an (English) manual.



Additional Information:

ASI mini cameras
The mini-cameras ASI174 and ASI290 have a beautiful appearance, small dimensions, low weight, the alone are already attractive features. The cameras convince by other advantages:

High sensitivity - important for finding the guide star
Sensitivity is the first thing ZWO has envisioned for these cameras. It is very important to find a guide star. Initially, ZWO considered only a monochrome sensor for use in its tracking cameras, since a monochrome sensor has a much higher sensitivity than a color sensor. Thereafter, the manufacturer has carefully compared the sensitivities of the available sensors. Ultimately, ZWO decided to use the SW sensors 290 and 174. As we know, the 290 and 174 monochrome sensors have about 80% maximum quantum efficiency and can therefore perceive more stars in the image field. Also, the shutter speed of the guide can be shortened.

Focus position as with the eyepiece

ASI Mini and eyepiece can reach the focus in the same place. You can focus with an eyepiece and then put the mini camera in the 1.25 "socket.



Works at the OAG

The ZWO mini cameras are well suited for tracking with OAG, they have a much wider focus than normal ASI cameras. You do not have to worry about the focus camera not focusing on the camera at the same time.
