Did someone say long range scanners? \o/

Long range scanners are definitely worth it for the cherry picking kind of explorers. Not for scanning distant stars, but for cutting down on scan times on individual planets. You save roughly 10-15 seconds per planet you scan, in a normal system. That's one jump saved on every 4-5 planet you scan.
If you prefer scanning everything in systems, fast scanners are superior. Scanning all the moons around a gas giant in half the normal time? That pays off pretty fast, I'd say.![]()
VY Canis Majoris well before the modded scanner. Also after that distance I just gave up, scanned it and left.

I wonder what's the max range without mods and with long range mod...
