These video tutorials are to ease the new users into the wonders of Pixinsight
I will not be talking too technical during the videos concentrating on the how and leaving the why for another time

I can assure you once hooked on pixinsight you will wonder how you ever managed without it!
I hope they are of help and let me know if you have further suggestions
