Yeah, I thought of the 24mm too, but the 27mm Panoptic has a field stop of 30.5mm, which is getting close to twice that of the 13mm nagler (17.6mm). The 26mm T5 Nagler is a perfect fit here, with a field stop of 35mm, but at $300 more than the Panoptic is really pushing things....
There is a part of me that says get the Pan, which would be a fantastic eyepiece, and more affordable in the short term, and another voice that says save for the Nagler, it would be the perfect match for the 13mm I have....
With the money I save by going for the Panoptic I could then afford a good 2" filter.....
But the Nagler would be sooo good.....maybe just be patient....
