Another update to my M16 Eagle image
May 24, 2020 16:24:58 #
Another update. I might have found a fits file that I processed just now which has one stacked image that took 133 frames@1.42 sec each totaling 189.38 seconds total. So how i understand it those 133 frames are 133 subs, am i correct?
I'm also including the camera info about the stacked fits file.
It still seems crazy you can get an image like this in 189 seconds at f6.3
I'm anxious to put it on the Hyperstar III and carefully collimation the scope/camera.
Still a steep learning curve with software, camera and filters, etc.
Thanks for your comments and suggestions, Charlie

Hi Charlie!
Nice to have your first name.
Very nice image of the Pillars of Creation in the Eagle Nebula.
If I had to critique anything, I'd ask about the stars being a bit blobular. But I chalk it up to the stacking.
But you are making great strides!
If you don't mind, I would like to share one of mine to help you see what you want to get out of your efforts.
This is 10 each, 60 second exposures, 600 seconds total (I think).
But the "Rainbow Sprinkles" are hot pixels. I'm infamous for those.
Back when all I had was my G3 camera, all I could do was long exposure imaging. So I became known for my "Rainbow Sprinkles" AP style. Shrug.
I got really good at tracking, because I could not stack to save my life. So I stacked with time, as Mathew in North Dakota told me. I'd just set on an object and suck the light out of it.
But 5 colleague's here also tried, and they all walked away scratching their heads. The files were just crap.
So take heart in that you can stack, and that you will only get better and better.
So I hope you don't mind....

Alberio{Charlie} did you use Sharpcap live stacking to do this? nice job you got it ! Correct , 133 is your subframe count . Sometimes , I have to use Sharpcap for dso imaging but, I also save individual frames so that I can stack my own and get rid of the ones that drifted . I can't wait until I get some clear skies again , it's been too long without being able to enjoy the night sky. Keep'em comin.

The stars being bloated was the first thing that irritated me. I think I wasn't truly focused, and thanks for the comments, your image helps for comparison. Have you tried subtracting dark to take out the sprinkles?

Yes it was SharpCap but I'm not sure if it was live stack or just Capture, I'm still getting a feeling for what the camera and software are capable of.
Thanks for the comments, much appreciated.

Ah, but those bloated stars are going to shrink. Because you are going to improve by leaps and bounds.
My Infinity camera is self-stacking. I can do a lot of control when I want to. But I'm lazy, I'd rather let it run sometimes, and save in intervals.
Then I do very minimal Post Processing. I'm not sure if that one has any PP.
I do have a good recourse in my most basic Photoshop Elements 12. And have filters to clean my later images.
But the one I posted is from 2017.
Yup, Post Processing Minimalist, that's me.
I'm an Astroimager. Not a Astrophotographer.
