M42 Might be able to detect a green hue?

[Kedvenc]

I'm a relative nooby with all this. According to Turn left at Orion is says 'Under perfect conditions you might just be able to detect a slightly green hue in the nebula...'

I found this an odd statement as when I view the nebula (through a 4 inch reflector and much more so in my 8inch reflector) it is a definite, unmistakable glowing bright green nebula. I see this in all sorts of sky conditions.

It also says that the nebulosity in m45 is difficult to see which I also find fairly easy to pick out. (and I've checked it's not due to dew, so to speak).

How many people see this that easily? I assumed this was the norm but maybe not.

perhaps some people's eye's are more sensitive than others. good for you though, ive not seen any green nor neblosity in m45 from my town location.

have you dark (ish) skies then ?

[Kedvenc]

I do have dark skies (very rural) and will get the 4 inch collimated and look through that again (haven't used it for years) just to make sure I was seeing the colour. I got my new scope only a few weeks ago and one of the first things I looked at was M42; it blew my socks off it was so bright and green. Like I say I pretty much thought this was normal, so if not, I feel very lucky.

What do you see when looking is it grey?

[Simms]

From my suburban area its a blue/gray area - cannot see a lot unless I get a very clear night and allow my eyes to adjust for a good 30 mins - would love to see some green in there. With M45 I see zero nebulosity, just the stars..

Colour me jealous!

I used to definitely always be aware of a green Hue with the 200p Newt but I see a bright white & grey now with the 12" LX90 ...

Green for me - or greyish blue depending on seeing conditions

There's an interesting article in the Feb. issue of Astronomy about the nebulosity of M45. During the 19th century, scientists had a bit of an argument about whether there was any nebulosity or not. Sometimes it can be seen with a small telescope under bad conditions while it may disappear when viewing conditions improve.

It was greenish for me even through a 60mm refractor, but that was a very long time ago as a teenager, nowadays every nebula is grey!

[blinky1983]

Yeh it appears greenish/blue to me most nights of clear and steady skies. In my 5" it was always grey but as my scopes grew in size i noticed the colour in m42.

Always appears to be green when I look at it too

[Astronut1982]

It always looks green to me with both my 80ED & my 12" dob. It doesn't matter if I'm observing from my back garden or out at a dark site, it always looks green.
