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

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'
