Mapped colour milky way imaging

[tornado33]

Howdy
Here are some mapped colour "multi spectral" images.
First one is where the red channel is an 850 Nm infrared image, green is 7 Nm H alpha and blue is from a UHCS filtered colour image.

2nd image is where as with previous one red is infrared, green is oxygen 3 (baader o3 filter used) and blue from the colour HHCS filtered image.

3rd pic is a unfiltered colour image, where red channel has been replaced by the 7 nm H alpha image. Any ionized hydrogen stands out like a sore thumb lol.
All images taken with 50mm f1.8 lens camera piggybacled onto the 10 inch scope.

Wow very interesting. You should submit these to APOD and/or SpaceWeather.

Very ncie shots.

Thanks :)

Nice exercise. It shows what is real to me more clearly than a straight 'natural colour' image. Can you think of any other combinations and or colour assignments.
Here is a natural colour image of the same region.

:eyepop: :eyepop: your not just good at taking very deep impossible objects, but also widefield stuff! great shot scott.

thanks all, heres one with infrered assigned to red, H alpha assigned to green, and O3 assigned to blue.

I should also mention that on the whole, the O3 filter isnt that useful for imaging, I dont seem to get much nebulosity, in original images only brightest bits of lagoon neb. and others appear. They are virtually gone in infra red, but H alpha really shines for nebula imaging.
Ps, nice image Bert was that with your LPR filter?

Yes it was taken last night with a 58mm Hutech LPR filter on the front of a Canon 85mm F1.8 at F2.8. I was testing out my 'new' stepping motor lens focuser. Works great, 1000 steps is about 0.2 mm lens focuser movement. Will post pics in DYI. Right now testing on the 300mm.
