M16 - Eagle Nebula

Hi,
I was glad that the moon rose reasonably late the other night so I could image the Eagle Nebula before it came up over the horison enough to wash out the image.

Taken with 8inch newt, Canon 350d modded, guided, 8 x 10min at ISO400.

Post processing PS CS2. calibrated.

Thanks for viewing

Oh yeah! Great shot Paul .Superb colours and focus. You just need to sort the drift in guiding but you can actually salvage this shot with the PS star rounder plugin. Worth doing. Nice work

Yeah - wasnt happy with the stars. Thought maybe guiding off but looks more like drift so will check alignment. Here is a star rounded version! Also, bit blue so re did backgound! Thanks Marc.

Wow, I love that Paul!
You've captured some beautiful depth without blowing the whole thing out. Most people end up with bloated stars on M16 too, particularly if they crop in a bit - at first glance I thought you must have included Ha data.

Great going.

Actually, the more I look at it, it is Ha isn't it!?

Thanks Gary - 10 min is about what is needed to get some decent detail from the Canon 350D IMHO

Hi Paul,

Excellent details but is it just me or is that a tad too red? The whole thing including the stars just seem red tinted? Both of them I think.

Just a critique, I hope I can get as good results with my 200mm soon.

Cheers

Chris

No Chris - your right. Red, lots of Red! I looked this nebula up and I think you might need narrowband to get some good colour variation of this region. I checked the histogram and the numbers, it looks balanced - so I figured it was simply rich in Ha gas.

I did do a repro with slightly reduced red but it knocked out a lot of fine detail.

I would like to know others thoughts on this though - as it is a good question!
