The ASI 290 MM Monochrome USB Guide Camera offers you very good performance for planetary imaging as well as for guiding. Low read noise, high dynamic range, AR protective window and much more are just some of the key characteristics that set it apart from the competition.
Guide Camera Mini Series
A guide camera uses software to assist in control the telescope motors to keep track of a guide star to keep the telescope aligned. (For telescope mount systems with compatible motorised tracking available)
The ASI290MM Guide Camera is the mini version which has the ability to fit / connect to different types of equipment such as guide scopes and Off Axis Guiders.
The ASI290MM Mini is designed for precise guiding. The 2.9um pixel size gives you a higher arcsec/pixel than the ASI224 or ASI120 camera. This means that, in the same guide scope, the ASI290MM Mini can detect movement of stars to a higher degree than the other cameras. ASI290MM Mini will improve your guiding precision with around 30% compared to the ASI120MM Mini.
The camera size, stability and ease-of-use as well as its ability to fit with different types of equipment eg; guide scopes, OAG etc.
The most important traits. Let’s face it, when you set up your equipment for a night of imaging, you just want things to work and to see that smooth graph on your guiding software before you start your imaging sequence.
In order to do that, there are some things to consider (apart from the points mentioned above):
It is not recommended for primarily deep space photography, AOC suggest a fan cooled model for all deep space object long exposure photography.
