Clamping range OTA sizes for Baader Solar Filters

Nick would you recommend using a solar filter infront of the scope if I am using my Altair Herschel solar wedge or can I get away without another filter? I am thinking either on my 73mm or 103mm aperture refractors.


Hi Terry you can use the Altair Solar Wedge without any filters in front of it on refractors up to 165mm diameter, (I will test on a 180 soon) and you can tune the brightness too to get faster frame rates or to use less gain. Best, Nick
