A Blue Eagle.

[Tandum]

Slowly coming to grips with these new NB filters and thought I'd have another go at M16 tonight while the weather holds, as the last try was plagued with problems and ended up sort of dark green :sadeyes:

10" newt @ F3.8, QHY9 @ -35C Baader Filters.

3.5hours of 10minute subs binned 2x2 with 80 minutes of Ha & O3 (5min subs) binned 1x1 for luminance.

This one is getting a lot closer to what I want, but more data is always good :P

Nice colours Robin plenty of detail more data is allways good

[ptc]

That's coming along nicely in my assessment


Must be pretty high in the sky for you blokes!

[renormalised]

It is, it's almost straight overhead:)

[Tandum]

The fast newt helps a lot in sucking in the potons but long exposures with it need very still conditions :(

I'm getting a flip around 9:30 and it'll go behind trees around 2am. But shooting anything west of here, across a city of 2 million is amazing. It just can't be done with RGB :) I buggered up the scaling on this one. I scaled the 1x1 shots down to 2x2 instead of the other way around :P

Robin, the colours look good but it looks like you have been using smoothing too much. Several areas look a bit blocky to me. Do you have a larger image that we can look peruse?

[Tandum]

Nope, not yet but it's clear again tonight for some reason, so I'll get more data and repo with correct scaling. I used noise reduction to reduce the magenta stars so that may have caused some damage to the 2x2 image.

Looking like clouds and rain starting tomorrow through to Wednesday so I'll make hay on this before I head off to Astrofest on Thursday ;)

[edit]
Here's a quick rehash with tonights data. There seems to be noise in the Lum frames. It looks like you need a weeks worth of data to smooth it out :( I'll work on it.
