computer redo, and new image of the horse
Hi Guys, I had a disaster last week, hard drive on my observatory computer
died, and this was a samsung SSD I got 2 years ago so I would "never have a
hard drive failure", so much for that.
Could not even run backup to save, and finally got a new computer.
Thank goodness I keep all my data on seperate data drives, so.. lost
nothing (900 images and subs going back many years).
I am up and running again, all data restored. bad news took me a week to
copy and reset everything, good news it is all working again and I have the
latest and best processors and C drive is one of those new NuVeSSD 2 TB,
and able to transfer both data drives over to the new computer.
I occ get a 'time out" on imaging, and it is clearly the USB hub in the
dome by the scope. I am getting a startech industrial level USB that is
rated to 40 below zero to hopefully fix that.
anyway, did a new image of the horsehead, see attached. Slightly sharper
than my prior but not significant I think.. the stars however are clearly
tighter with blurX
Happy holidays... and keep good back ups of all your data!
Mario
So sorry for your ordeal, Mario.Reinforces the value of backing up to a remote hard drive, which has been my practice for years.
Very nice tight image of the Horsehead with pinpoint stars.
That's one of Blur X's amazing advantages; stars in RGB can be as tight as those in narrowband.

I redid my M42 photo from scratch and this time used linear noise reduction and Blur X following DBE.
Result is attached, along with a close-up of a transition section of the image that demonstrates how clean the background sky is after using Multiscale Linear Transform.
This is really great tip, as conveyed by Mario. I found, surprisingly, that MLT is so powerful in smoothing out the background sky, I could not use it at full power (it blurred the edges of the nebula too much). In my M42 photo, I only applied MLT to layer 1 at settings of 3.00.1.00. 1Normally, you would apply MLT to 4 layers at diminishing strengths: 2.50, 2.00 1.00 thresholds, for example.
Blur X did a nice job sharpening detail in the nebula's "currents," but its most noticeable effect is reducing the size of stars.If you position its slider "sharpen stars" at max. (0.50) most of the small stars will disappear. In this image, I used 0.33.
It is actually amazingly good at eliminating Milky Way stars if they are superimposed over a galaxy, like M31.Poof, they are gone and the galaxy is clean.

Excellent image and detail
We need to talk about all the new processes at next Monday session
The entire sky needs reprocessing and redoing :(
I am a bit miffed after suffering 40 plus years of imaging that now “anyone” can get a mount Palomar like image with little effort !!!

Your sentiment is echoed online in PixInsight videos I watched last night, thanks to Blur X.
FYI - Adam Block has a nice intro to Blur X on YouTube. As he and others point out, just applying the presets makes one's jaw drop.

Yes his video is a must watch, all of his are
For January we need to explore blurX, process steps, and linearfit which I find excellent as an early step
