    Help with star-testing scope

    star testing can be a challenging read and it requires good, steady skies to make a definitive assessment. Even then, one side of focus should show some rings and some of the more obvious aberrations. Bright outer ring on one side sounds like turned edge, but shouldn't affect things much at...

    Why was Nikon EDG pulled from western markets?

    Thank you, I think analog was the wrong term to use, but perhaps a 'close relative.' Quite often, the listed FOV and focal lengths of an eyepiece doesn't always quite match the actual performance. I have yet to put the eyepieces on a bench with reference patterns, but that's something I'm...

    The Cleaning or possible objective lens replacement of a West Germany Zeiss 8x30B T*

    I would be cautious about overseas purchases of older optics where there is no detailed picture of the objective / lens groupings. Japan is subject to much higher humidity and many optics have been lost to fungus. I would argue that the majority of optics that get fungus that sits for a long...

    Greetings from Long Beach, California!

    Thank you for the warm welcome! I'm looking forward to expanding my bird observing skills and enjoying all of the things there are to see. Us astronomical visual observers are sometimes chided for spending hours chasing after 'faint grey fuzzies' in the deep sky, so birding has been a great...

    Greetings from Long Beach, California!

    Greetings, BF members! One of the other hobbies that I am very involved in is astronomy, which led me towards doing more terrestrial observing and birding with my astronomy equipment. One day while under quarantine and doing some observing of the sun, I decided to setup one of my...
