Same theory as per my link above, just use it for the IC tool rather than BPP. ie save it as a process icon.

I see. Thanks Juan.

Thanks mate. If I understand that correctly, it's saying BN isn't the same as colour correction, but my question was actually the other way around. If I just did CC, do I need to do BN? If the answer to that was in there, I must've missed it.

General / need b/g neutralization if using colour correction?
« on: 2012 August 29 01:49:01 »
Something that's often puzzled me. I usually do a BN first, then do a CC. But in the CC dialog, using the same background as the BN process. So is the separate BN step redundant? Can I save myself a step by just doing CC?

Been quite a while now, thought I'd resurrect this thread as it's still a bit of a mystery to me. Anyone able to answer some of my original questions?

General / matching star or nebulosity intensity between RGB and NB filters
« on: 2012 August 27 04:03:36 »
Say I have 2 images of the same nebula target, same gear, one taken with a broadband red filter, the other narrowband Ha. The stars and continuum objects are brighter in the R filter, but the nebulosity S/N ratio of the Ha is better.
I'm trying to figure out how to:
- match the star brighness in each image, so the stars look the same but nebulosity is stronger in the Ha one
- match the nebulosity brightness in each, with the dimmer stars being in the Ha one
Any ideas? Could just eye-ball it with histro-trans, but figure there's a more mathmatical/scientific way with PI as there usually is.
I'm getting back to working through http://pixinsight.com/tutorials/narrowband/theory/en.html and in there, the nebulosity is same brightness but Ha has weaker stars.

I think many agree with this. I posted this a while ago, and there were some useful responses you may be interested in.

Release Information / Re: PixInsight 1.8 — New File Explorer window

That's not fair, Juan, making us drool over new features before it comes out. Waiting with anticipation.

The docs that Juan has written, like the image integration one, is a wealth of knowledge. It's more like a textbook than an application's documentation. Masterful.

No arguments from me, Rogelio 
I'm gradually chipping away at a few mates who have PI but only use it for one or 2 features, not the whole workflow. Admittedly, one of them is using a WinXP (32bit) OS and it has some issues there, another has an underpowered computer (doesn't meet PI's min sys requirements), although there are ways of managing both of those issues.

G'day Eddy,
This is probably more of a question directly related to the BPP script itself. This tutorial was just a way of having it remember things between sessions.
I'd ask your question here in the BPP script thread directly.

General / Re: Binned vs unbinned color
« on: 2012 August 06 07:00:34 »
Correct, Geoff. You need to consider the image pixel scale binned and unbinned, relate to such things as seeing conditions as well.
In terms of exposure times, there's discussion above about sky background limited exposures, but there's also saturation points to consider at the upper end of the scale. And my Kodak 8300 sensor (QSI583), for example, exhibits some blooming/overflow (not sure of the correct term - it's not true blooming) at binned exposures of very bright stars, but not at 1x1. So if I have a very bright star and binning does this overflowing, I've either got to look at multiple exposures and some sort of HDR or exposure blending, or go unbinned.
