Product Highlights

Quantum Efficiency

The QE curve and readout noise are very important parameters to measure the camera's performance. Higher QE and lower readout noise are necessary to improve the image signal-to-noise ratio.

The peak quantum efficiency of ASI662MC is 91%.

Based on internal testing and calculation, the peak quantum efficiency of ASI662MM is 91%.

This new HAC125DX (Honders Advanced Catadioptric) Minigraph is the smallest, fastest telescope dedicated to astrophotography available today. 

This type of telescope, called an astrograph, is designed from the start to take photos of the night sky. You don't look through it, instead it connects to a dedicated astronomy camera from ZWO, QHY and others. This updated "DX" model features a rear focussing mechanism. The 16mm imaging circle well suited for IMX533 and IMX585 based cameras.

It's fast too, at just f/2.0. This means shorter exposure times and you won't even need to worry about autoguiding.  

Heading out boating? Like to check out birds near the water or go whale watching from the shoreline? Or maybe even venturing into the great outdoors when conditions are less than ideal?
