A couple of other safety tips.
Keep the front cap on the finder scope or make another filter for it from the offcuts of solar film
Be sure to put the filters on before aiming at the sun and remember to swing away from the sun before taking them off. (Seems obvious I know but I forgot once when packing up some time after an eclipse that the mount was still faithfully tracking the sun and within a couple of seconds of removing the filter the eyepeice cap had a nice neat pinhole melted through it! I keep it as reminder as to why you should never look at the sun through an unfiltered instrument.)
