Centering object in eyepiece using GOTO scope


Recommended Posts

Hi

I'm fairly new to this, so please excuse if this is a stupid question.

When aligning stars using the GOTO Skyalign feature on a Celestron I'm never certain if the selected star is accurately 'centred' in the eyepiece. I am a spec wearer but try with and without. It's more how centred does it need to be. I've heard about cross-hair reticules but is their some accessory one can add to the eyepiece so I can align to some reference point.

Thanks Paul

Paul,

To be honest for visual work not having the star bang on centre won't matter. I tend to use a low power to first get the star in the field of view, place it more or less in the centre then change eyepiece to a higher power and get that in the field of view and then confirm the position. I then go back to a low power and repeat for the second star. I find that this is good enough for goto visual observing

I used to find it easier to jusdge the position of the star if I defocussed it depending on how bright the image is you may be able to get it to almost fill the view...

Peter's idea is good but in all honesty it matters little unless you are trying to image the near-invisible. It is just as easy to re-centre on a nearby object if accurate GoTo (ie very accurate) is needed.
