    Default Star Hopping



    I'm wondering if you do the star hopping with your eyes, or with the scope. I mean, say you start at arcturus to get to a nearby object. Do you find arcturus with the naked eye, then find a closer star with the naked eye and the find where the object should be with the naked eye and then point your scope there, or do you get arcturus in your eyepiece, then get the closer star in your eyepiece, then find the object moving from the close star to the object all while looking through your eyepiece? The ladder seems harder but is that how it's done?

    Personally I use my quickfinder to get in the general area first according to my starmap, then I go to the finderscope to narrow the field and if the object is nto apparenet in my fov on the finder i start comparing stars through my finder to the map and just start hopping towards the area all the while doing checks in a low power eyepiece.

    I use my Telrad to get to my starting point and then use the finder in conjunction with the charts to star hop to what I want to see. I have an overhead transparency that has a circle that will cover the same area on the chart that my finder covers in the sky. Works really well.

    I find my target in Stellarium, then point to the general area of the sky find a distinctive asterism. Then I flip Stellarium and star hop from there.

    I like to use my Telrad and the associated charts along with Stellarium to get close using visible stars if possible. Once I've judged the approximate position I do a little searching around. More often than not I'll find what I'm looking for. If that doesn't work I'll generally go back to the charts and try to match up specific stars using my 9x50 RACI after putting myself close with the Telrad. Lately, since I did the Telrad mod to Stellarium I don't even bother with the charts I just take the laptop out with me. I'm kinda slow at finding DSOs but I usually get there eventually.

    Personally, I always have a pair of 10x50s when I'm at the scope, and use them as a bridging point between charts and sky.

    Tonight I've been looking around Auriga, Gemini, Taurus and the top end of Orion, so as an example - lets say..... ngc2169, the '37' cluster, which is in the upraised right arm of Orion.
    With binocs first, started from Betelgeuse, then moved across to 'mu', and on towards 'nu' and 'xi' - it's fairly transparent here tonight, so even with the 10x50s, the 'haze of the cluster was easy to see, and even a star or two resolved.
    Then to the scope - start with the finderscope on the nearest EASY naked eye star, which is Betelgeuse - then follow pretty much the same track as I went with the binocs - and switch to the scope when I think I'm 'on' the target.

    If the target is invisible in binocs and finderscope - then I'll find the spot I think it should be, first with bins - then finderscope - then jump to the scope, with my lowest power, widest FOV eyepiece, until I locat the target.

    If the star-hop is VERY easy - for example, another one from tonight - M1
    I'll just put the sope on the starting star (Zeta Tauri, when hopping to M1) - and work my way from there using the scope on low-power.

    I can't recommend the binoculars enough though - a great way to get a 'feel' for where the target is, before switching to the scope.

    Gotta agree with Carlos there, quick and easy way to suss out the stars. Bino's are with me when I am out at the scope always.

    I use a red dot finder followed by the finder scope. I use charts that I print using Voyager 4.5 with the correct orientation for the scope I'm using.

    Absolutely Gordon. Thanks again for the info.

    Good advice from Carlos as well. Binoculars help in getting oriented especially if not many stars are visible naked eye.
