After locking the Dec and RA, a satellite whipped through the 63x view... I love when that happens!

This double is the center of three stars, the upper left of which is in a tiny 'keystone' asterism. After locating the field with 63x, I needed to kick up to 147x to detect a slight oval-ness.

226x showed a grey split in 'thinner' moments of another band of wispy 
cirrus clouds moving through.
