A cautionary tale here. When I ordered a 1.25" solar wedge from Lunt it came without the ND3 installed. Fortunately I wasn't blinded as the glare from the eyepiece was so strong I barely caught a glimpse before pulling my eye away. When Lunt sent me a 'replacement' filter, it soon became obvious the design had changed, and there was no way to retrofit one and still be able to seat en eyepiece. I ended up changing over to a 2" unit. Don't take any risks here - if there is not a very dark piece of glass in the wedge, do not look through it!
Cheers,
Andrew.
