Quote:I'd be doing amazingly well just to see the galaxy, I think. Anyone know a minimum aperture for PGC 69457 in a green zone with typically mediocre seeing? (Loaded question, perhaps.)

Quote:Thanks for the comments on Einstein's cross gentlemen. I really appreciate the experienced guidance you offer up to those of us that are new to this hobby. My buddy and I have the tools to nab this object. The only variables seem to be the transparency and seeing. Sooner or later we'll get this.

Quote:hmmmmm, my challenge is a bit lamer than most Ive read here. Mine is to finish what I started 3 years ago.I began the Astronomical leagues Messier Club.I managed to knock off 73 in a year, and at the time was certain it would be done by the following summer.Well life just seemed to bring this project to a halt. But to bring this back to the topic, I have 6 items for the winter/early spring groups left. M79 in Lepus , M46-47-93 all in puppis, and M63 and M94 in Cnanes Venatici .Modest goals I admit, but I really hate leaving projects unfinished.

Quote:The Cone Nebula, yes.
Quote:Quote:The Cone Nebula, yes.The Cone Nebula is a true challenge object. It's far more difficult than B33.The only time that I've been able to catch a glimpse of it was through a 30" Tectron Dob at New Mexico Skies (magnitude 7 skies at an altitude of 7,000 feet).Dave Mitsky
