    Astronomy Adventure - Finding Neptune

    Even at the highest magnifications that I can realistically get with 4.5 inch telescope, the planet Neptune is virtually indistinguishable from a star. So the only way to really know you have seen it is to track its movements over the course of a few days. These two photos were take about a week apart in late September of this year and you can see how Neptune has moved in relation to the background stars.



    Technical details:

    Scope: Starblast 4.5; tracking on
    Magnification: ~30x
    Camera: iPhone6 using NightCap Pro; ISO 8000
    Photos: 1x15 sec. image
