Having a play with the HDR composition feature of PixInsight. Am curious to see whether this approach will improve the dynamic range potential of my images on my old 12-bit modded 400D
First is the LMC, comprising 20 calibrated 4min frames @ ISO400, and 26 calibrated 4min frames @ ISO1600, captured with BackyardEOS using a modified Canon 400D and Nikkor 135mm AI prime @ f5.6.

Second is the Orion region, this time with 20 calibrated frames of each of the following: 30sec subs @ ISO400, 4min subs @ ISO400, 4min subs @ ISO1600. Again captured with BackyardEOS using a modified Canon 400D and Nikkor 135mm AI prime @ f5.6

Am not convinced I'm getting the most out of this data, but I still have my training wheels on with PixInsight.
Constructive criticism welcomed.
