focusing the telescope at infinity, or by considering the air shower as an object to be imaged, in which case one might focus the telescope on the central region of the shower. The issue is addressed using shower simulations.doi:10.1088/0954-3899/27/4/416Hofmann, Werner...
How to focus a Cherenkov telescope 来自 Semantic Scholar 喜欢 0 阅读量: 25 作者: W Hofmann 摘要: Cherenkov telescopes image the Cherenkov emission from air showers. A priori, it is not obvious if the `best' images are achieved by measuring Cherenkov photon angles, i.e. focusing the ...
Two pieces in a telescope make this possible: The objective lens (in refractors) or primary mirror (in reflectors) collects lots of light from a distant object and brings that light, or image, to a point or focus. An eyepiece lens takes the bright light from the focus of the objective...
To focus a telescope with a camera attached, you simply need to turn the focuser knob until your subject comes into view. Most of the telescopes amateurs use for astrophotography (Here are the ones I recommend) will have dual-speed, 10-1 focusers, and the ability to lock the focuser in ...

Focusing my telescope using a Bahtinov mask and the ASIAIR focus tool. Why Focus is Critical for Astrophotography In general, the smaller the stars are in your image, the better. One of the reasons I love apochromaticrefractor telescopes, is their ability to capture colorful, pinpoint stars. ...
The focuser has two dials on either side and turning these will allow you to focus the view through the eyepiece. As for theeyepiecesthemselves, your telescope most likely came with two to get you started.9The eyepieces slot into the focuser and you’ll notice there’s at least one small...
Third, watch the the video, about 20 seconds in, where the Barlow is being put in the telescope. Look at the front end of the telescope. Do you see how much it is shaking just putting the Barlow in? It's going to shake that much or more when you try to focus it. ...
Insert the 20mm eyepiece into the telescope's focuser. Turn the focus knob until the object appears sharp in the eyepiece. Remove the 20mm eyepiece and insert the Barlow lens into the focuser. Insert the 20mm eyepiece into the Barlow to achieve 105x. Adjust the focus knob to sharpen the im...
