IC1848 Soul nebula in HA

Astrolog: 

After fixing a badly tilting focuser on the Skywatcher ED80 and guiding problems due to the differential flexure introduced by having the QHY5 - 8x50 Finder set-up a bit higher than it should be with a finder shoe, It was prime time for testing long subs in the 20+ minutes exposures. Soul nebula is a rewarding target for Hydrogen Alpha acquisition, and i will be revisiting for OIII and SII.
Enjoy!!

Astronomy object details: 

Westerhout 5 (Sharpless 2-199, LBN 667, Soul Nebula) is emission nebulae in Cassiopeia. Several small open clusters are embedded in the nebula: CR 34, 632, and 634 (in the head) and IC1848 (in the body).
The object is more commonly called by the cluster designation IC1848.
Small emission nebula IC 1871 is present just left of the top of the head, and small emission nebulae 670 and 669 are just below the lower back area.
This complex is the eastern neighbour of IC1805 (Heart Nebula) and the two are often mentioned together as the "Heart and Soul".
