Hi all!
This is my picture of NGC 3199 and Westerlund 2! These two are faint little buggers! I'm pretty happy with this, i only wish i got more data! It still looks pretty nice though!
I took this at LMDSS in heathcote, vic.

Equipment used:
CGEM mount, autoguided
Takahashi MT-160 at f/4.9 (reduced from 1000mm to 776mm)
Canon EOS 700D DSLR
ZWO 60mm guidescope/ DMK21 guidecam
Image data:
ISO 800
5 minute exposures
45 frames
Taken with SGP
Processed in Pixinsight
Processing details:
Preprocessing:
Select best images with subframeselector
Calibrate with darks and bias frames
Debayer frames (removes a DSLR's CFA - more info here )
Align frames
Stack with imageintegration!
Linear phase processing:
Crop a bit
roughly align colour channels with linearfit
DBE to remove gradients, while being careful of faint nebulosity
PCC - calibrates colours using stars as a reference
Deconvolution (corrects for atmospheric effects using a star reference)
Add stars back in via /u/burscikas 's method
Small amount of TGV and MMT denoise using this method
Linear stage:
Arcsinhstretch to bring out the data, this is a really great stretching tool to keep colour!
DarkStructureEnhance to add more contrast to darker areas
Curves for adjusting brightness and colour
Saturation
Morphological Transformation to shrink stars quite a bit
Sharpening with MLT and thats it!
Thanks for checking out my post!
