Fantastic effort Pat. Hopefully in the not to distant future I can achieve similar results with my iOptron. Unfortunately with limited time I don't get the opptunity to travel to darker locations. I was rather disappointed with the ioptrons finder scope. Hoping it was going to be bigger with more magnification to locate sigma but living 8kms from Melbourne that's no chance. Most I've achieved is 45 to 50 secs using my iPhone's clinometer and compass. I've actually just ordered a digital clinometer and a good quality compass so hopefull I can zero in closer to achieving polar allignment. If not they will be handy tools when I get the chance to travel away from the city.
What exposure times are you able to achieve Pat?
