    1. shoot off tripod
    2. shoot manual
    3. use 500 (600) rule. Your built in crop factor might mess you up. Shoot with increasing exposure length to see when the stair trails start and cut that in half. Use that cut in half number to figure what number to divide your focal length into.
    4. use prime lens (nikkor 20 f/1.8 set a little lower than 1.8 is really good but there are better - I've found a Tamron 15-30 f/2.8 at 15mm almost as good as nikkor 20mm f/1.8). If you're stuck with some sort of zoom set at minimum.
    5. use a high iso (as high as you can). If there is too much ambient light keep your exposure long and reduce iso until the results are exceptable. Your camera will have a iso limit where going above will have a bad effect.
    6. use a shutter release.
    7. set color temp around 3800-4000K

    Dark Sky Finder (there will be a simliar site for your area) dark green will produce acceptable result but blue and gray are what you are really after.

    He should be able to do almost all of it. I've ran into birders in the field with these camera the iso and color temp can be changed. I bet his pictures will be fine. I'm more worried about any built in crop factor his camera has.

    So you don't even try unless absolutely perfect? You could easily shoot galaxies, milky, planets etc.

    I did go to a number of these places and although you can get shots of the milky way they are not that good There is just to much light pollution on this side of the country. There is nothing to compare to being able to go out and stand and look up and see the entire milky way from horizon to horizon

    You just don't realize that he can't take a milky way photos with the Nikon P900. This camera has auto limits even at "M" manual shoot.

    For example, at ISO 1600 the larger exposure you can choose is 2" and 3.6f aperture.
    And at ISO 800, the larger exposure is 4" with 2.8f aperture.
    If you choose 15" exposure the higher ISO you can choose is 200 with 2.8f aperture, so the photo youˇll take is a black background.

    You need at least 15", ISO 1600 and 2.8f aperture to take a decent shoot of milky way, and that's not be able with this camera.

    If 15 sec is the longest the p900 can do it is not the right camera for shooting stars ........unbelievable the camera was not made to shoot longer exposures

    Re: Help with astrophotography P900

    My problem has always been focussing. It's manageable if there is a Moon to focus on first but trying to focus on a cold Moonless night is very frustrating. I have similar problems on my D5500 - modern cameras have lots of cool features but I miss genuine manual focus where the focussing ring has proper end stops.
