KAS member Tim Kurtz made a timelapse video of the aurora from a couple of nights ago. He used a Canon 90D and took 200 3-second images with a 10mm lens at f/4.

If you can, run outside and look for Comet Lemmon (C/2025 A6) RIGHT NOW! You'll need a pair of 7x50 or 10x50 binoculars to spot it.

The Moon will hinder viewing a bit this weekend, but it's supposed to be clear. If you head outside for a little stargazing, be sure to download our free October Night Sky star map. It'll help you identify the bright stars that'll still be visible. www.kasonline.org/files/1025ma...
