    That is why I jumped to astrophotography ... it is not that complex job to get Rosette, Heart, Soul etc. to show up in winter skies. If you live Northerly enough, North America Nebula should also appear

    I wouldn't actually say seeing M31 naked eye is a sign of truly dark skies. I live in a typical suburban location that usually ranges in the Bortle 5 to 6 range. I can always see M31 naked eye. Granted on the poorest of nights its subtle without optical aid, but its always there. But a key factor here is experience.

    More times than I can recall I have shown someone with little deep sky observing experience a galaxy in the eyepiece and they simply cannot see it. It is very obvious to me, but they see nothing. They don't have their eyes trained to see the sometimes very subtle variations between light and dark through the eyepiece. That comes with time at the eyepiece chasing objects that are approaching threshold levels.

    Filters can be quite useful if one knows how to utilize them. I have some, but quite honestly, I don't regularly utilize them. Regarding color, some objects can be bright enough to allow you to see color. Mostly that is in the realm of high surface brightness planetary nebulae. This is typically a bluish, greenish and blue-green tint. That can depend on how the invidual's eye interprets color in low light conditions. The vast majority of them will look whitish or grayish to be honest. The Orion Nebula (M42) always looks a pale greenish tint to my eye. Some folks report seeing a tinge of pink in it as well, though I never have.

    But again, a lot of experience can make or break many observations. There really is no way to get around the learning curve if one wishes to visually pursue deep sky objects. Particularly those that linger near threshold levels for a given aperture and sky condition.

    Well I found tons of galaxies and viewed 5 nebula tonight m42 m43 m78 crab nebula and owl nebula. All we're grayish blue except 42/43 no idea why I see Soo much color in this one and nothing in the others

    Soon Sagittarius and friends will be gracing our night skies and there is lot more to be found there. Everything from nice bright nebula to GC and galaxies. A true treasure trove waiting to be seen.
    There is plenty out there and as mentioned a more experienced eye sees more, so relax and enjoy the journey!

    I have seen color in M42 on different occasions. Once, it was striking, with obvious pink, dark red, green and teal. I have never seen it like that since, although I have seen the pinks and greens in more subdued grayish hues. I have seen a greenish hue in M57. Once, the Andromeda Galaxy was so vivid it almost appeared pale golden. But those were rare occasions. I have no reason to think that I will see color in an object as faint as the Crab Nebula. I know I will not see color in galaxies like M65. It is impossible. You are not doing anything wrong and should not be puzzled at not being able to see color in objects that nobody else sees color in either. There are other objects people report seeing color in, but M65 is not one of them.

    Gotcha I though crab was one some people see color in. The area below leo that is like a cluster ball of messeir and ngc objects will be visible to me in about a week. I've been looking forward to that breaking the tree line since I noticed it (:

    I rarely see color in anything except the Orion Nebula, where there are perhaps a few hints of red and blue apart from the usual greenish appearance in the 18", no color with smaller apertures. I thought I saw a bit of color in the Flaming Star Nebula last year but I haven't been able to replicate this observation. Good times are coming for both galaxies and nebulae, so hang onto your hat. Sounds like you getting the hang of observing!

    Well the new scope with a telrad and that amazing finder makes it a butt load easier. I'm about to modify again to add skeye to my scope for push to application when I can't find something. I'm still working on Galaxy observation though. I have yet to see dust Lanes í*˝í¸*í*˝í¸*í*˝í¸*. Soon though soon pinwheel will be viewable and that is face on so I'm hoping with going to a out 16mm I should be able to pick up dust Lanes.

    M94 will be overhead nowadays. It is quite a bright galaxy. Not very known and no show-object. But quite obvious!

    In my whole amateur life I have never seen colors in nebula's or galaxies, although I have some experience. Suppose its is my eyes. So I would be more than happy to have seen as much color as you have! Much comes down to the earlier mentioned experience level, but since you have already observed the Owl and a bit of color in M42, I am certainly not gloomy about your future observations. Keep on searching and things will become better!

    In the meantime: M94!

    Good luck and clear skies!

    Hello Mary,

    with your ultrahigh sensitivity to the colors, you are our Lucky Mary!

    There are several effects on the color vision in dark.
    When dark adapted, the central foveal sensitivity becomes shifted to green (508nm), also known as the Purkynje effect.
    The averted vision becomes shifted towards blue (450nm), and that's also the reason why the telescope eyepieces
    (and binoculars) with high transmissivity at 450nm and shorter wavelengths, reveal more galaxies and more HII nebulae.
    Whereas the light sensitive rods achieve the best sensitivity threshold within 10 seconds up to 20 seconds integration time, the colors sensitive cones may require up to few minutes. Therefore, some waiting on the colors is helpful.

    Lots depends on your blood circulation and oxygenation capability. It is a good advice to go to a cardiology medical doctor, and to get checked, even if you are still feeling young. My perception of colors in dark has slowly but significantly improved since a medical treatment of a heart issue about 1 year ago.

    Back to the Andromeda Galaxy in golden color.
    This is the reason why the light yellow filters help to reveal the dark lanes close to the core of the Andromeda Galaxy,
    and in some other bright spiral galaxies.
    That's a forgotten old school tricks, used during the old times in the black and white astrophotography with the photographic films and plates.

    Best,

    JG
