Description

This is my first narrow band image using my new QHY600M-PH camera.  The combination of small pixels and full frame field of view make for a nice single frame of nearly all the nebula including Eastern Veil (NGC6992, left), Pickering's Triangle (top center) and Western Veil (NGC6960, right) and other features.  I imaged with a tilt in order to place the three main sections in vertical orientation in order to make the composite picture of Revision E.  However, in retrospect I now wish I had tilted further in order to capture more of the southerly wisps of this region to complete the full frame picture.  I acquired the frames over several nights but ended up having to throw much of the data out as I had to contend with both cloudy weather and smoke from wildfires.  In the end I got just enough suitable data to produce this, but I must say this has not been a good summer for imaging in the Pacific Northwest.

For the color balance, I took different steps than usual.  First, I stretched the three narrow band channels separately before combining.  Then, I chose a modified SHO palette using the following formulae:

R = 0.75*S + 0.25*H
G = 0.5*H + 0.5*O
B = O

Typically, I start with the straight SHO palette with one color each, but this time I went for the desired color balance through PixInsight's PixelMath.  Following that I increased the saturation and overall stretch.

I also included a High Dynamic Range Multiscale Transform (HDRMT) step in order to bring out more of the details of the brightest regions, which otherwise would have been over saturated.  With this step, I could also show more of the faint wisps of the nebula without washing out the brightest sections.

The Veil Nebula is a popular and well-documented deep sky object that needs no further elaboration here.  I have documented it elsewhere in the past.

I hope you enjoy this first published image from the new camera.  I have earlier acquired wide band data that I wish to process and publish soon.  Hopefully, I will still be able to get some clear nights in which to do some further imaging before these "good" summer nights are over.
