The seeing from my backyard where I do a fair bit of my observing is pretty poor (heat plumes from my own and neighboring houses, etc). I have a Pentax XL 5.2mm eyepiece but often the resulting image is soft and shimmery while the lower magnification image provided by the 7mm ocular is not as badly affected. When I observe from places where the seeing is better I reach for my 6mm and 5.2mm eyepieces far more often.
