Tadpoles and Flaming nebulas - Ha only

[AstroGS]

I was playing around with the Ha filter, while testing NINA, the focuser and the tracking and managed to acquire approx. 23 frames of 300 sec. Trying to learn how to improve my stretching techniques in PI. in this image, I performed the stretch in small intervals while trying to keep  the faint Ha nebulosity visible.

Very nice @AstroGS.  Were you using GHS to stretch?

[AstroGS]

Thank you @Ouroboros - yes indeed. I used the GHS. I think I did 3 or 4 samples of it before I was almost happy!  Although I am into astrophotography for the lat 3-4 years now, I just start to understand the importance of stretching and how to do it. I am sure at the hands of someone that is more experienced than me, can get more detail by performing a better stretch.

It took me a while to realise how critical stretching is.  I was misled by the simple dropping the STF stretch onto the Histogram Transformation tool so frequently demonstrated in introduction to Pixinsight videos.
