If you haven't seen Jupiter for ages, but you know what constellation, and roughly what bit of the constellation, it's in from, then any old software should do, as you should be familiar with your zodiac, recognise those constellations and their order without even thinking, and have a rough idea how much later the constellation you want will appear simply based on that. Sure, gotos and drives are lovely, if they can be afforded (the extra cost could be put towards more aperture or high quality eyepiece), but in the old starhop universe, especially if you were observing at least a few times a month, you should know when Jupiter is going to be visible within half an hour or better from your location without even using software. The pixellation is better because the images are updated to higher definition ones, for HD screens, not because the software is better or more accurate on zoom in, as this was true down to the arcsec for software a decade or two old, especially if they chose a sensible projection algorithm for their planetaria. Nowadays vendors can either get them from observers who are willing to donate or sell them dirt cheap, or use SDSS or PanStarrs sources, maybe even making their own and reprocessing to make new stitched mosaics and brew their own RGB conversion of g', r' and i' images. Most likely they came from RealSky, or if downloaded form online, came down in the reduced resolution compressed to save download size, even in big hard drive and broadband times, instead of the full blown. In this one you've got to remember that the older stuff will only have low resolution images to play with, hence the zoom in pixellation. Whoever programmed this had to be a genius. Reason #2: While I'm doing Reason #1 (configuring and enjoying the pictures of all the big nebulae), no matter how much I zoom in or out (no matter the resolution), the pictures and placeholders for all the nebulae size and scale accordingly, without becoming the least big pixelated.
