I have a Questar 3 1/2 telescope with a full aperture solar filter.
It will allow me to watch the moon cross the sun. It will also allow me to see sunspots.
I’ll take it off at totality. Hope I can see some red prominences.
But I better put it back before the end of totality.
NICE! I used to own a 6” Quantum, but sold it years ago. It wasn’t nearly as good as your Questar. I’m planning on observing the Moon’s transit across the Sun with my refractors, a 115 f/7 and either my 80mm or 72mm f/6 scopes. I have Baader solar film for 2 scopes and a Lunt Herschel wedge for the third.
The Sun will be, at maximum, 80-85% covered where I’m at.
