Description

IC-410 reprocessed using a clean stack created with ASTAP.

Notes to myself:
start ASTAP
Select Lights, Dark and Flats
Frames were rank and deleted based on the following rules:

1-HFD : HFD is the image median, a lower value is better.
2- Quality : Star count divided by HFD - A higher value is better.
3-Star Level : High values are better. Too high may indicate satellite(s)
4-Background : Sky darkness and transparency. The lower the better. High values are clouds
5-Sharpness : Lower values are better. A measure of change between dark and bright pixels.

To align RGB channels use Alignment method [Stars]
To align the RGB channels use Blink tab, select the three fits file RGB and push button marked >]
and click Export. Files are marked with title_aligned.fit

Image C: Previous version of IC-410 stacked with a different program

Good improvement between Original and previous version Image C.

Conclusion: A good stacking program is key to creating and processing images. If data is not good due to clouds, stacking more and more data will not improve the image, however, the stacking software will alert you to the fact the data is poor and should be removed.
