    Re: CP-300/U Star Finder

    I have a 2102D and also a CP-300/U, also known as the Computer Celestial Type CPU50A/P. Never used the 2102D much and the other not at all. Looking at both items, it appears that the CPU50A/P might give more accurate readings, but wonder if the difference would be significant in practical use. My efforts at celestial navigation are limited to shooting the sun and moon when they are both visible, or the AM and PM sun standing on the beach in North Carolina, and or using an artificial horizon in the parking rear of the apartment complex we inhabit in Pittsburgh, where the sun does not shine all that often, it is said. Unfortunately, I've gotten rather rusty, essentially my fault, but so it goes.
