Astrophotography Performance

ASI120 mini camera offers you very good performance for planetary imaging and guiding. Low read noise, high dynamic range, AR protective window and much more.

High QE

Absolute QE Curve, we estimate the Peak Value is almost 80%.

120Mini VS 120MM-S

Compared with ASI120MM-S camera, 120mini have smaller outlook, lighter weight, and it can reach focus at same position with eyepiece.

USB2.0Port & ST4 Port

USB 2.0 Port: Mini camera has one USB2.0 type C port. Type C port is very popular in mobile phones, it will not care about positive side and negetive side of the adapter.

ST4 Port: Can connect mini camera direct connect to auto guide port of mount.

ASI120, ASI174 and ASI290 mini camera have very beautiful outlooks, small size, light weight, this is not a big deal.

We should consider much more…

How to choose a good guide camera?

Many people may say : must be small, suitable for different equipments(guide scope, OAG), stable working.

Yes, I think thoes are basic demands for a good guide camera, and ASI mini camera can do them well.

So, what else we do care in the deep of our mind?

I think there will be three potential requests: high sensitivity, precisely guiding, big FOV.

ZWO-ASI-guide-cameras

High Sensitivity

Sensitivity is the first thing we considered. It is very important to look for a guide star. So, at beginning, we were considering to use mono sensor to design our guide camera only. Because mono sensors have much higher sensitivity than color ones. Luckily the ASI120MM Mini, ASI290MM Mini and ASI174MM Mini all have very high QE peak value – about 80%, which can detect more stars in view and shorten the exposure time in guiding.

Entry Level

ASI120MM Mini

ASI120MM Mini is designed for newcomers, which is more affordable than ASI290MM Mini and ASI174MM Mini. You can easily get the well-sampled stars with the help of ASI120MM Mini. It’s light, compact and robust. If you are still wondering which one you should choose as your first guide camera, the ASI120MM Mini can always be a good choice.

Precisely Guiding

290mini

ASI290MM Mini is designed for precisely guiding. The 2.9um pixel size can give you a higher arcsec/pixel than 224 or 120 camera. Which means in same guide scope, 290mini can detective slighter movement of stars. ASI290 mini can improve about 30% guide precision than 120mm.

Big FOV

ASI174MM mini is designed for Big FOV guiding. This is very useful in OAG to looking for a guide star. When you use OAG guider working with Ritchey-Chretien or Schmit-Cassegrain telescope, the hardest part is to looking for a guide star. ASI174 mini have 1/1.2″ big sensor which means you can have a 4 times bigger Fov than 120mm.

Smiling Face

ZWO-ASI-guide-cameras-2

The back of ASI mini camera is like a smiling face, its mouth is Type C USB port, which is widely used in mobile phones. And its nose is the ST4 port, for guiding. Every time, you use mini camera, there always will be a smiley face stay with you in the dark nights.

Focus like a eyepiece

ASI mini camera can focus at same position as eyepiece. You can focus with a eyepiece, and put ASI mini camera into 1.25″ holder.

Work with OAG

Mini camera is very suitable for OAG, it has much biger focus range than normal ASI cameras. Never to worry about that guide camera can not focus with main camera at same time.

Work with CS adapter and CS lens

Work with 1.25″ extender

ASI 120mini camera is available now! You can buy it form us or our dealers! Wish you all have clear skies!

Blake – May 19, 2020:

Hi, what is the maximum amperage draw the camera can use? I am going to be plugging it into a usb hub and am making sure there will be enough power for all my devices. Should I assume the camera will always use the maximum of 500mA at 5V from its host?

- Moson – May 20, 2020:
  
  Yes, you could assume the camera will always use the maximum of 500mA at 5V from its host. And it’s OK to use no more than 500mA at 5A.

Can the ASI 120 mini fit into the ZWO 60mm guide scope? and also what would you recommend using for guiding, 120 mini with the ZWO 60mm or the ZWO mini guide scope? thanks

- Moson – May 8, 2020:
  
  The ASI 120 mini can fit into the ZWO 60mm guide scope.
  Both ZWO 60mm and ZWO mini guide scope can be used for guiding with 120 mini.

Chris – April 27, 2020:

I purchased the ZWO ASI120MM mini for guiding. When I attach it to my guide scope which is a Altair MG32 Guide Scope, I can’t get it to focus at all. Also, when I try to run PHD2 with the camera, all I receive from the loop is a white screen, exposure time doesn’t affect it really or gamma slider

  You could adjust the helical focuser at the front of the guide scope to get focus. Or try to pull out the camera a little.

Philippe – March 31, 2020:

Hello,

When this camera is used as a guiding camera with Zwo OAG, does it require the 5mm adaptor ?

Furthermore, can the Zwo 1,25” helical focuer be used in order to precisely focus the camera ?

Thx

Philippe

- Moson – April 3, 2020:
  
  Yes, it requires 1.25″ extender and 1.25″ helical focuser can be used to precisely focus the camera.

Michael Hettrick – June 9, 2019:

What is the dark current of this sensor ? (a graph of electrons/sec/pixel as a function of temperature would be ideal; if this is unavailable, then the electrons/sec/pixel at a single temperature would be better than no info.)

0

- Katherine Tsai – August 14, 2019:
  
  The dark current is related to the temperature and expsure time, ASI120 is not a cooled camera and it is meaningless to talk about the dark current.

Peter – February 8, 2019:

Hi, I plan to buy the 150deg lens to my 120mm mini. Does it fit also in an 1.25 draw tube? In case I’d check the primary – secondary alignment through the camera view?

0

0
- Sean Wang – February 13, 2019:
  
  120mini camera can work with a 150deg lens, there is a CS adapter in camera box. and our 150deg lens diameter is smaller than 1.25″, so you could put it into 1.25 draw tube.

Jim Miller – August 2, 2018:

Has anyone been able to get this camera to work with PHD2 for guiding? Which driver should I use and what gain settings? I get nothing but noise. The camera works fine with Sharpcap.

0

- Sean Wang – August 3, 2018:
  
  Hi Jim
  I suggest you use Sharpcap to focus and find out exposure and gain settings. Then set them into PHD2. You can use native driver or ASCOM driver in PHD2, they both fine.

I just received my asi120mm mini, many thanks!

Having installed the latest native drivers and ascom drivers from your page, I’d like to report that phd2 doesn’t currently recognise the asi120mm mini native driver, only through ascom. Sharpcap recognises both.

Thanks
