Reprocessed M104

[ZeroID (Brent)]

I took this image quite a while ago in my earlier attempts and was never happy with the outcome. Today I reprocessed it with FITSWORK recommended by Gary Beal ( thanks) as an experiment to see how much better it could be. I won't show the first image, it was washed out, brown and grainy. And I'll say FITSWORK is an unusual piece of software to come to grips with. There is a good starter tutorial on
http://intervalometer.appspot.com/Fitswork.jsp because there is almost nothing at the website.
Anyway here is the result of my twiddling.

Nice, Brent. How many subs and what duration?

Ta Guys,
23 Frames , 20 secs ISO 800 through a KM 7D ( 6 megapixel) DSLR and the 10" f5 scope. No filters.
It was also looking back over my house roof at the time, winter (June) so possibly thermals had little influence.
The original image was very washed out and diffuse and also brown toned with LP. So quite impressed with what the software is capable of.
