“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

Quote:After that, I don't need a finder eyepiece. I just use the finder! All I need to do is place the location of an object at the crosshairs of the finder scope. Even at mid-to-high power, that object will be in the field of the main scope.
Quote:Mike, If it weren't for my 57mm IPD, I would have a pair of Leica ASPHs!
Quote:A finder scope is useful if the object itself is visible in the eyepiece or for starhopping.A finder eyepiece for the main scope is useful if the object itself is not visible in the finder, which if there is a substantial difference in the aperture between the magnifying finder and the main scope, may often be the case.
Quote: Quote:I'm going to snag an f/5 mass-market Dob for use during my semi-annual dark sky camp-outs, and want some "guiltless use 'em and abuse 'em" eyepieces to go along with the dob. Here are my requirements. I will just say this: These trips represent the best conditions you are likely to experience during any given year. Take your best and enjoy it because this is when quality equipment can really shine. Coma and astigmatism are partially hidden by less the pristine skies, when the skies are dark and clear, the difference between "affordable" eyepieces and the good ones are most noticeable.I might spend an evening in my backyard with my TV Widefields and TMB Planetary's but the Naglers always go to the dark sites....

Quote:As long as the finder scope and main scope are very closely aligned, I don't really need to see the object itself in the finder scope. All I need to do is center the location of the object under the crosshairs of the finder. I use the finder scope in tandem with SkySafari on my tablet. IME, this is a great combination for star hopping to the location of DSOs.After centering the object's location under the crosshairs of my finder scope, I merely look in the eyepiece of my main scope and the object is there. Usually the only problem is if the object is just too dim to see in the main scope.Mike
