Astrophotography Performance

ASI174 mini camera offers you very good performance for planetary imaging and guiding. Low read noise, high dynamic range, QE peak 77%, AR protective window and much more.

High QE

Absolute QE Curve, we estimate the Peak Value is about 77%.

174Mini vs. 174MM

Compared with ASI174MM camera, 174mini has smaller outlook, lighter weight, and it can reach focus with eyepiece at the same position.

USB2.0Port & ST4 Port

USB 2.0 Port: Mini cameras have one USB2.0 type C port. Type C port is very popular among mobile phones, it doens’t matter with the  positive side and negetive side of the adapter.

ASI120, ASI174 and ASI290 mini camera have very beautiful outlooks, small size, lighter 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.

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 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

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

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

Work with OAG

Mini camera is very suitable for OAG, it can have 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
