Saturday Night Live at York River St Park;  Apr 13th 1st event that hasn't been clouded out for VPAS in many moons.  Have here M101, 30 exp of 60 seconds ea using Meade 8" ACF riding on EQ6;  Nikon d750 uv/ir iso 1270 . PHD2 guiding. Processed in APP.  Seeing was forecast 2 but we all thot it was better; Transparency above average following system that blew for days. Nippy but no dew.   1st time, used Tri Bahtinov mask (and asiImg) to collimate ota; small but noticable tweek to collimation (using honorable defocused donut).  The TriBaht did the trick. After years of blobular clusters.
