Observing Notes

Andrew Cooper
Jan 12, 2008    Hale Pohaku, Mauna Kea, HI (map)
46cm f/4.5 Deep Violet

Clear dark notch in the nebulosity of IC434, with averted vision a little more detail becomes apparent, particularly across the 'top of the horsehead' (west side), fairly large at 5'x5', NGC2023 quite obvious just 10' northeast

Andrew Cooper
Nov 23, 2006    Las Cienegas NCA, Pima Co., AZ (map)
46cm f/4.5 Deep Violet

Dark bay on the brighter strip of IC434, poorly defined even with the H-Beta filter borrowed from Sam Rua, large and very dark

Andrew Cooper
Dec 27, 2002    Sentinel, AZ (map)
46cm f/4.5 Deep Violet

An easy target with the UHC filter and the 35mm Panoptic eyepiece, most of the 'horse' outline is clear, just not under the 'chin'

E.E. Barnard
25cm f/5 Astrograph

Dark mass, diam. 4', on nebulous strip extending S from Delta Orionis (see Ap. J., 38, 500, 1913, and Plate XX).
