Selected Observing Notes from September 2010 at IHOP
Observed on Sept 5, 2010

There were seven of us at IHOP and we enjoyed great skies.  NELM was about 6.9, but seeing was average.  Since the transparency near the horizon was excellent, so I decided to start near the southern horizon fishing out planetaries in Sagittarius.

This list is part of my total list and highlights interesting objects.  All objects listed here are in my downloadable observing guides.  Enjoy and hopefully you will try of these objects.  Note:  The comments are straight out of my observing notebook, so they may be a bit short.

Equipment used:
22” f/4 reflector with no tracking
20mm Pentax XW finder eyepiece
12.5, 9 and 7mm Baader Genuine Orthoscopics
10 and 6mm Zeiss ZAO-II Orthoscopics
5mm Takahashi LE
TMB 1.8x ED barlow
Lumicon O-III filter
