I love them all! (all the ones I use anyways, except the Superview
) Hard to pick a fave because I always swap them around a lot until I find the sweet one. I use the 19mm Panoptic and/or 13mm Stratus for initial overview of the target and for general gazing at sizable DSOs. But then the detective work is always done with orthos and plossls. If I was only allowed to have one (plus my barlow), it would be the 19mm Pan.
