I’m wondering about using a Lunt solar wedge with an AT102ED. I’m not sure if this is an air spaced objective or not. I believe I read somewhere that it’s best to use the wedge with an air spaced objective. Does this matter or not?
I also have a Meade 120/f8.3 achromat I could use if that’s a better option.
This would be for future solar observing, mostly thinking about the 2024 eclipse or whenever I felt the urge. I’m thinking the 2” would be the best choice since it works with anything up 150mm.
I will be getting a polarizing filter also. Is the single filter best?
Any input is welcome, especially if you have experience using the wedge. Double especially if you have experience using the wedge with an AT102ED.
