Very good seeing today prompted me to try eyepieces I don't normally consider with the PST. I began with the usual 10mm Sirius Plossl, then a 7mm TMB Planetary and finally a 6mm TMB II Planetary. the two Planetarys put up fine, steady images with more contrast than the 10 and sometimes 7.5 Plossls give on average.
This warm and windy day with a cold front moving in had the best seeing I recall in three years using the PST. First the H-a view with the beautiful SE prom that Andre has so elegantly captured:
