    This may be of interest to backyard skygazers – the Stellina, an automated astrocamera that works in conjunction with your smartphone. Everything’s automatic: initial orientation, target location, shooting the picture (actually a set of stacked images), and offloading to your phone or the cloud. Not cheap at $4K but looks like fun! Here’s a review with samples.

    The latest Sky & Telescope also reviews the Stellina, and found several things also to not like, especially its shortcomings in dealing with the moon and the planets--the reviewer found Stellina's images of Saturn to be no better than what Galileo's primitive telescope showed him. I think most amateur astronomers would rather pocket the $4,000 and spend it instead on something with a larger aperture, though likely less compact. The question will be, how often will Stellina be used by the gadget-loving probable purchaser?

    Here’s a sample image from the Stellina, doubtless a very long exposure with some extensive image-stacking (taken from digitaltrends). Not too sharp, but I suspect Galileo would have been willing to trade some significant body parts for a piece of kit like this.

    This is the view of quite a few DPR readers, who also think a more capable setup can be had for the price. Example: "It’s for people of means with a passing interest in astro but unwilling to put any effort into it. After using it a few times it will end up gathering dust."

    With hindsight, it seems obvious that cosmic rays from outside our solar system would affect chemical processes in planetary atmospheres.....wow.
