    Default Tracking the sun with a telescope?



    Hi,
    So I was trying to figure out how to track the sun with a telescope?
    I'm a newbee.. so excuse me if this is a stupid question.
    I have a Celestron SE6 and didn't see an option to track the sun. I know I need a proper filter for it and everything, but I was just wondering how you guys track it? Is it in the celestron HC menu and I'm just missing it? Or maybe I need to use an app to do it?

    Thanks!

    You can track using Solar System align, but the Sun is not normally included as an option, for safety reasons. To include it, go to Menu -> Utlities -> Sun Menu and press ENTER.

    All you need to do is actually simpler than going through your regular alignment procedure.

    You go through the regular procedure just telling the scope it is centered on the alignment stars which you can't see, just tell the scope it is on it. The goto will not be accurate, who cares you can't see anything other than the sun anyway. But the tracking will work just like normal. You will have to manually slew (with the HC arrows) to the sun and once you are on it the mount will track it.

    Don't forget to cover your finder scope if you have one!

    My question is how do you actually point the scope at the sun accurately. I have a solar filter on my Mak 127 and have the finderscope covered, but I have the devil's own job lining it up in the eyepiece

    One way is to watch the shadow of the scope and make it as small as possible. You could also uncover the finder scope and watch for sunlight coming out of the centre of the eyepiece.

    When we were observing last May's Mercury transit with our astronomy club, the following method was suggested and worked very well.

    Ensure the solar filter is mounted properly over the objective
    Ensure the finder is capped - either with some solar filter or with lens caps.

    Slew the scope so that the shadow of the scope on the ground is as close to a perfect circle as you can get. That will give you a rough alignment.
    Look through the Eyepiece to see if the Sun is centered - if it isn't remove the eyepiece and look down the focuser tube. You should be able to see the glow of the sun's light from one side of the focuser. Use the handset to move this glow to the centre of the field of view.
    Replace the eyepiece. You should be sorted.

    I've seen Solar scopes with a solar finder consisting of a pair of discs - the front disc has a small hole which projects the sunlight onto the rear disc - the scope is adjusted until the projected dot is centred on the rear disc.
