Hello
Who can recommend a spotting scope? There is a need to take a picture of an object 3 feet high at night under orange sodium light (street lighting), at a distance of approximately 200 yards. I thought or the C90 Maksutov by Celestron, or the Barska Colorado 90mm, coupled with a cellphone camera. But perhaps a different scope should be used? Thanks much! Farfarello. |

I have a C-90. It works fair to the eye but it is a F/13.3 lens. You will need a camera that can shoot at 1600 or 3200 ASA speeds to get much of a picture. You would do as well to spend the same $250 on a camera like the Nikon S 9900 that has a 30x lens. Not sure of the subject you are shooting, but picture quality will be low on both at 200 yards.
Welcome to the OT. |

Folks ain't got a sense of humor no more. They don't laugh they just get sore.
Need to follow the rules. Just hard to determine which set of rules to follow Now the rules have changed again. |

3_tens,
Thanks for your response. The object is a box and an experiment I am conducting. The aim is to get color change of a circular area on the face of that box of a rough diameter of 10 inches. The contrast should be high, between bright and dark. The experiment itself is a long story..What is a fair distance for such an optics? 100 yards? Thanks, Farfarello. |
