8. CommentsSame wind... 5mph sustained gusting to 10, mildly troublesome, 28 degrees. Dark - good views of faint objects. Enhanced contrast of Nagler may affect my perception of the darkness. Not too bad a night to concentrate on diffuse objects with a borrowed Nagler 13, though. Whoa! What a huge field! Makes finding objects with easy even with poor goto pointing. Sixth grader had good time viewing lots of faint objects. Wife said
