I finally found it this night at about 8:35pm (more or less)
I could observe it in both a Celestron 25mm WA and a Baader 12.5mm Ortho on my 150mm GSO Reflector. Initially I thought it was a relatively small globular cluster. Then I verified with stellarium none are so close to M71 and finally by
Cartes du Ciel identified it was the Garradd comet.
I tried last week (in the only night without clouds) to find her (the Italian "Cometa"takes the female gender), without any luck, such I thought it wasn't bright enough for my gear.
I couldn't see the tail but hey it is my very first comet saw by a scope
The attached image is a screenshot done with stellarium. Garradd position (more or less) is in the center of the overlapping Telrad pattern and highlighted by a pale red circle.
I also added what I reckon it may be the path Garradd covered since last week (I approximately knew then where it was by Cartes du Ciel).
If this path is right, I should find her tomorrow following it.
I hope this image may help others to find her. Please let me know if it actually will work for you
