M1 The Crab Nebula - Reprocessed Data From Last Year

#1

Post by Juno16 »


One nice thing about AP is that when the skies do not cooperate, you can always go back and reprocess data.
Even though there isn’t the thrill of newly captured data, the re-process is always fun and gives you the “feel” of being out there again especially when you feel that there is an improvement.

This is an image of M1 that I captured in January of 2021.

I ran it through the latest Pixinsight version 1.8.9-1 and ver. 2.5.4 WBPP utilizing Local Normalization and drizzle (1x, no increase in file size or processing time).
Plus, I have some new tools like StarXterminator and NoiseXterminator and Bill Blanshan’s quick GHS stretch and star reduction tools (pixelmath).

I like this process much better. Please offer any comments positive or negative that you have.
Thank you very much for looking.

Hey Jim. I don’t think I saw the first one but this image of the Crab Nebula is fantastic. Not over saturated with colour and clearly showing the complex knotty filaments. It’s a beauty, buddy. Nicely done!

Hi G!
I really appreciate your nice comments!
You might be able to see the original version if you scroll down the Astrobin link, but I’m not sure since I have an account.
The stars were splotchy and eggy, the nebula colors were different, and the stars within the nebula showed ringing from poor settings in deconvolution.
It’s nice having 10TB+ storage in my pc. I save everything!

Like I told G, I think if you open the image in Astrobin, you can scroll down and see the original version.
It wasn’t bad, but had a few issues that I could help with being a tad better at processing.

Hi JT,

The almost two year old data had elongated stars (my old AVX) and I had to "fix" that (took about two minutes). Other than that the data processing was really smooth.

The original process was about two months after I started using Pixinsight. Going on close to two years now and I have so much more to learn.

I know that we talked about moving to PI years ago and I am surely glad that I did.

Thank you for your nice comment JT!

Hey Jim, thats a great example of why we should consider reprocessing older data with newer tools of software versions.
The original was nice but this is head and shoulders (if crabs had head and shoulders!) above it. The background is nicer, stars tighter and better colours, nebula itself is smoother without halos.

Mighty fine job indeed Jim!

That is a LOT of internal structure brought out without overdoing things. Nice improvement in your processing regimen, Jim!

I appreciate your nice comment! The original process was after a few months into Pixinsight and I was kind of “plucking “ around. Another 10 years and I might have it!

Hi Bob.
It’s hard to not get carried away with targets like this and I tried to keethings tamed down a little bit, but it ended up with a little bit of “pop” anyway.
Thank you for you very nice words!

Great processing on a gorgeous target. I haven't imaged this one in over 2 years, time to try again.

Really need a bigger scope to do this target justice.

I thought about cropping, but decided to leave it as-is.
Actually, it’s the first time I’ve used the auto cropped masterlight version in the new WBPP. If you have an updated to the latest version yet, it’s got a few nice surprises.

I hope you get a chance to image the Crab soon.
This data was from January 2020 and I would like to add some more time on it too!

Thanks a bunch Steve!

I have used the WBPP script a total of maybe 5 times. Some day I may go back and try it. It often failed to stack my photos so I did it all manually and never stopped.

I get that Steve. Really is the same thing as manual pre-processing, just lumped into one package. I have had a few issues that could have been sorted out better if I was pre-processing manually, but the PI developers have really made WBPP into a nice feature rich package recently that is very stable (at least so far for me) and works very well.
If I had several failures with WBPP, I would be doing all of the pre-processing manually too.
