![]() ![]() Therefore Pluto should be accessible to backyard astronomy. And I’ve managed to pick up mag 14 stars in my photos with the Skywatcher 80ED with 60sec exposures. Of course, equipped long exposure cameras you can have a smaller telescope, but a high focal length would be preferred to reduce to better pick it out from the background of stars. ![]() What size of telescope does it take to observe an apparent magnitude 14 object? Based on the theoretical limits it should be possible to make visual observation with a 10in aperture telescope, but most would say you need a 12in if you plan to observe with an ocular. Pluto as viewed by New Horizons during flyby (14 July 2015) – NASA The planet will track west as the night advances. See the sky chart below showing the southern part of the sky at 10pm EDT. By looking straight up, you will be looking through a smaller “air column”.Ī good time will be on April 10th when the Moon will next to Jupiter. Wait until Jupiter is high in the sky, that way there is less atmosphere between you and Jupiter.Past midnight is better as this allows time for the ground to cool especially after a sunny afternoon, reducing convective currents. ![]() Allow your equipment to cool down a few minutes such that the equipment temperature can stabilize and match the outdoors.Air turbulence whether within the optics, telescope, near the ground or high atmosphere will give you a blurry view. Planetary imaging is all about controlling turbulence. Some information on planetary imaging and processing is provided in my blog on imaging with a webcam. It is always better to take a series of images or videos with different settings and review them at a later time on the computer. Capturing the smaller moons require more exposure or gain, but at the risk of over-exposing the planet and turning Jupiter with those wonderful cloud bands into nothing more than a white sphere. Photos of Jupiter with the moons are a little tricky. ![]()
