Ghost Nebula from poor data

This is near Orion and I have never tried it.
Poor subs and not many of them and just used them as an exercise to push the software. I am not sure if features I brought out were even there.

It might be poor data but it’s still a great image , plenty of detail , contrast and nice round stars
Only criticism would be the colour is a bit flat and there’s a satellite streak across the lower part of the image
But still nice effort

Hi Martin
Thanks.
The colour is flat because its all a photo shop trick☺.
I have changed my view on a satelote in the image. After stacking all my Rosette Neb data which had up to three going through just on one frame, and there must have been maybe 30 subs with trails...so I was disappoimted that they did not come out...the joys of short subs and deed sky stacker..I may have a go at photoshoping it out for the sake of learning another cheat on decent work☺.
But I started with what looked like a black screen with a couple hints of light☺
I was going to throw it out but thought I would see what one can do...startools would not wipe it was that bad..never had such ever happened...nothing after using it...worked noise reduction way past any setting I have ever used.
It was surprising but so exceptionally different I doubt I will ever work on such a poor start...I hope to do a good job on it as looking a good images it is an interesting object and maybe somewhat overlooked because of the favorites around the region.

Some of the net images are beautiful.
Alex

Thanks Leon.
The result my not be what I hope to do next time...the object of this exercise was to ring out poor and minimal data by playing with all the wonderful softeware you can work with or in my case play with☺.
I should be doing other stuff but I decided to go thru what I class as junk...stuff that didnt work..I have some widefields that I should try the over the top processing...of course if I knew what I was doing it would not be a problem☺.
I have completed THE BOJAN WIDE FIELD mount, sorted out both the 50mm lens ..they actually work when used correctly☺...so I hope next trip to have clear skys as I cant wait to get wide fields whilst getting data with the scope on something else.

That's a pretty good result all things considered Alex, I reckon that's a target worth revisiting.
Cheers,
Tony

I had the gain way up ...but it was a bit of a test run I hope to do better next trip.
Lots of subs may bring it out for you...maybe see if others have had luck with a dslr.
