Perhaps you have one sitting in your eyepiece case not getting much use. If so, I'd like to buy it!
Ideal would be a 32mm Rini Superwide. Next, would be any of the 2" threaded for filters, near 20mm eye relief, and 62 degrees or more apparent fov.
But I'd be interested in hearing about whatever 2" Rini you might have in that 30-38mm range.
These sold new for $39.50 to 49.50.
Let me know what you have (condition, field of view, specs) and we can go from there!
