Quote:You can also see Rigel's secondary in a good 60mm refractor as well. One of the amazing things about refractors is how much less aperture you need to split a difficult star in comparison to what is required for an SCT or a reflector.John

Quote:I got the pup with my 12.5" last night after looking nearly every night for a month. I posted about it in the eyepiece forum but was unceremoniously I informed I was probably seeing a double image. Is Sirius b that hard to split?
I split Rigel the first time with a C90...thought it was no big deal...then it never happened again. My dob does it easily even in poor seeing.

“I am the only person to ever ace a 1951 USAF resolution test. My 'to observe' list says 'done'. I do not use charts or atlases when I starhop; men do not use maps. One of my sketches won an SBIG deep sky imaging contest. I am the life of star parties I have never attended. I never say anything looks like a faint fuzzy - not even a faint fuzzy. Pilots aim green laser pointers at me. Don Pensack proofreads my CN forum posts.” - The Most Interesting Astronomer in the Universe
