Who needs the corrector?The effect of atmospheric dispersion strongly depends on the elevation (height) of the object observed appears in the sky. The lower the object is in the sky, the longer the path its light takes through the atmosphere and hence the greater the dispersion produced. The bright planets in particular are not often very high in the sky, especially if you live at high latitudes. The ADC lets you observe planets, not only when they are high in the sky but even when rising and setting, with high brilliance and colour and without chromatic aberration. This makes you much more flexible in your choice of observing time. |
Three eyepiece holder thumbscrews, which make the connection more firm, more stable and more convenient to use. |
Improved attachment design features a brass clamping ring which provides your eyepieces with optimum protection from scratches or deep grooves, and provides a more secure connection. |
Thread for 1.25'' standard filters, use with a filter to watch the moon for better images. Effectively reduce stray light interference, the edge details of the image are clearer. |
There is a small spirit level at the top of the atmospheric dispersion corrector to better find the zero position of the ADC. |
