take pictures with the camera and a telescope entry level is a challenge, mostly because of difficulties related to the frame.
Focus becomes an heroic light as every touch of the focuser is an earthquake in webcam ..
also overcome the problems of the sensitivity of the focuser mount may not be enough for the delicate operations focus.
few little trick can help.
Here's how I improved the focuser of 130 newtons.
After checking with the level that the orientation of the focuser tube was the same, I added a thin line on the graph of the focuser tube, this allows the approximate location appunatre fire with different accessories. Then I mounted a small lever on the handle of the focuser, so you can have a greater sensitivity in the movement. The basic idea is very simple, with a longer arm to the same movimeto angular displacement is a greater need. The sensitivity of fuocheggiatre in this case has increased the ratio
n = R_Man / L_Br
with
R_Man : ray dela knob.
L_Br length of the arm measured from the center of the knob.
It 'important that the lever readily removable so as not to permanently restrict the movements of fuocheggaitore that otherwise could not do the full tour!
