Thank you all for kind feedback.
Rob, I agree, a bit rushed processing of data in PI and I am still learning how to use it effectively.
Alistair, this doublet is okay, but focuser needed to be upgraded and I really cannot use an OAG with this scope as I have to quite significantly adjust focus for each filter. I also have a small triplet by Orion (80mm CF) and optics in Orion are superior to this doublet, but the OTA n focuser in Orion are really not good for photography. One day will look into fixing issues with my Orion as I really like its optics.

Chris, I started organising batteries n cables n hoping for a few clear nights over Christmas to do narrowband imaging (HOS) somewhere a bit further away from the city and this nebula definitely deserves some colour :-)
