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 shall we 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 sensor have much higher sensitivity than color ones. After that, we carefully compared the sensitivity of our sensors. At last, we decide to use 290 and 174  mono sensor. As we know, 290 and 174 mono sensor have about 80% QE peak, can detect more stars in view. Also, we can shorten the exposure time in guiding.

Precisely Guiding

290mini

 

ASI290 mini is designed for precisely guiding. 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

174mini

 

ASI174 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, it’s mouth is Type C USB port, which is widely used in mobile phones. And it’s nose is ST4 port, for guiding. Every time, you use mini camera, there always will be a smiley face stay with you in the dark nights.

174miniVS290miniFocus like a eyepiece
