The Iris Nebula

I took this a couple of nights ago in my Dawlish back garden consisting of 73 x 300 second exposures. I'm pleased to have captured the dark dust clouds but more integration time coupled with better Pixinsight processing skills would definately help!
(Being lazy I’d love to hear of a way to combine new data with master files created by already running a night of imaging through WBPP? At the moment I start from scratch with WBPP using all of the original lights, flats, dark flats and darks from however many nights and use keyword of ‘night’ to separate… I hate repeating work!

Very good, especially at the lower end of brightness. I think the bright end is a bit too bright but I've no idea how to fix that in PI. In a sensible program like Photoshop 👹 it would take a click, a slider and a second click to sort out.

PI even has curves🤣

If it didn't, the data would remain linear - which wouldn't get us very far!

High Dynamic Range Multiscale Transformation, or HDRMT for short. But even in a limited program like Photoshop , curves with an inverted S shape may do a decent job.

PI vs PS, seconds out, round n…

Very nice, I started imaging this object a few days ago. If weather permits I'll have an image by next week

It’s easy. You extract a lightness layer and use curves to brighten the bright areas snd reduce the dimmer areas a little. Then you apply it as a mask and use curves to reduce the brightness of the brightest parts of the image.  Works great.  Although, it would be better to control the dynamic range in the stretching process.  That is more  difficult. Also, Sometimes it’s best to remove the stars before using curves, even with a mask. For small changes it’s not critical. But in this case, I think it would be. There are stars in the core.
