M13 Queen of the Stars

[Star101]

I tried M13 earlier, iusing short exposures of 10s upto 30s but could not get them to stack using PI. Watching a instructional video, it mantiones that stacking requires some stars to be visible before stretching. In other words...Longer exposures.

So, I pushed the exposure to 120s so I could see some stars even when the image was linear. This proved to work much better  Stacks all but the dodgy subs.

Managed 15 x 60s Lum

15 x 120s RGB. 

ZWO ASI 183MM Pro, Astrodon LRGB filters. C11 XLT, Mesu 200, Guided using PHD2 with ZWO OAD and Lodestar X2. SGPro and Pixinsight.

Thanks for looking.
