This fairly young waxing crescent moon was still visible from my backyard when I got home from work, so I very quickly setup my telescope and got some images before supper.  I tried a new Meade #128 3x shorty Barlow that just came in to see how it performs compared to my shorty 2x (a Meade #126).  My initial impression of the 3x Barlow is that the view is slightly worse; more blurry, more chromatic aberration…this all however may simply be due to my pushing the ED80 beyond its useful magnification level.  Before packing things up I aimed at Jupiter and gave my son a look.  He thought it was pretty neat (he’s 6).
