Meteor sighted in Cambridge UK?
I think I saw a meteor explode just now! Can anybody work out what it might have been? 4 October 2026, ~00:25 BST; due south; started ~30° above horizon; travelled ~10° diagonally down-left; very bright, with an apparent explosive flare/fragmentation.
Can a gas moon exist?
A moon (the size of Ganymede of smaller) composed entirely of gasses without any land (like gas giants)
Shadows?
In both the section and the full view of year 5 of the DESI scan, I notice a remarkably intact structure. But if I think about it like RADAR or LiDAR, I would expect to see shadows cast behind objects where light could not reached the scanner. Second question is how could DESI not punch through ANY of what I assume is the plane of the ecliptic that is cause the symmetrical scanning gap in the full view, if a can scan out extremely far in other areas.
Camera for Meade ETX 90
I've been using a Meade ETX 90 for about two weeks now and have been really enjoying it. It's become pretty clear that an iPhone camera, adapter or not, eventually becomes limited.
First, is a real-time camera being placed into an ETX 90 even plausible or a pipe dream?
Second, what cameras would be plausible for a telescope like mine, I've only ever seen the planets and moons with it so I'd be happy sticking to those. Although it really would be nice to get some snaps of some DSOs (particularly nebulae) but I'm keeping my expectations tempered. Especially if DSO level cameras come pretty steep, but I'd still love to know all my options.
I'm under Texan Panhandle sky with an SQM of 18.65 and brightness of 3.73
Is this Milky Way? Between Sagittarius & scorpion

Could a moon have rings?
not much information needed. Could a standard moon the size of Luna (earths moon) or below retain rings (like those of Saturn) and if it could, for how long could it retain said rings?
