Our eyes are target specific for certain, as different people have different sensitivity to different wavelengths of light. That's an absolute given!
I don't know that I have that much trouble with the Horsehead. I've probably observed it close to, if not more than, 200 times over the past 40 years, which is when I gained access to telescopes 12" and over. For the 10 years I observed prior to that with smaller telescopes, I never bothered trying to observe it, as I had other programs I was focused on. I've probably only ever tried to observe it in a telescope under 12" less than 5 times. As nice as small refractors are, and they do give an aesthetically nice image, they don't have the light grasp, or resolution that I want to use these days. To be totally honest I spend very little time with telescopes under 14" these days. Even my 10" SDM, as nice as it is, generally only gets used for lunar and planetary observation, which is why I got Peter to build it. Ill be observing under Bortle 2 skies December new moon and will try for the Horsehead in my friends new 5" Triplet APO with a H-Beta filter.
