Good catch Stefan,
Deb and I who are very new to Astro stuff found Catalina from our beer garden around 19:00 last night.
I could barely make it out in our 7x50 bino's and as with you could not see it in the finderscope.
Thankfully though we knew where to find it from charts supplied from here

We are very greatful to the person or persons behind this site as it has allowed us beginners to find Lovejoy, Masters, Panstarrs and now Catalina.
The beauty of comets is that our LX90 can't find them as a goto scope, which forces us to read star charts then guide the scope to target.
Love it and we hope to continue this side of the sky adventure.
