Hi Mickoid !
Thank you : ) I was pleasantly surprised by the outcome . I'm using a SW Ed 150 triplet . A ZWO6200 OSC camera and the ASIair plus . My stuff is on a pier mount and it has an 82ED Evolux as a guide camera .
Yes , my RA guiding is way too agressive , have yet to deal with it .
Im at Bateman Bay . Class 4 .
Yeah , I meant 2 second flats and .1 second bias , oops .
So I had 2 x 2 minute lights , 20 x 2 minute darks , 20 .1 second bias and 20 x 2 second flats .
I stacked the data in ASIDeepstack . I strecthed resulting stacked tiff image in the pixinsight histogram . Then extracted the background using starxterminator . I then used noisexterminator and blurxterminator on the background only . I then opened the background in Lightroom and made it look nice .
I then took both images back to pixinsight , using pixelmath to join them back together . I took the resulting image back to lightroom . That's it .
For the new darker Carina image below , I experimented and didn't even bother extracting the background . I just slightly stretched it and sharpened it in pixinsight and enhanced it in Lightroom .
