Stacked in PI with darks calibrated only
Processed in PI and final touch in PS
Cropped

So far up to now the best one I took in Hong Kong ever.

113. M104

Taken with DIY 6" F4 Newtonian + Vixen 1.4x extender PH + 1600MM in YL @850mm F5.6
RGB=4x180s : 5x150s : 5x150s, autoguided with SXD mount
Stacked in DSS without any darks, bias and flats calibrated
Processed in PI

A test to see if this old Vixen goto mount SXD can still do autoguiding well with 3.8 um pixel sized imaging camera.

115. Ring Nebula

Taken with DIY 6" F5 Newtonian + TV parracorr + 1600MM in YL on July 12 @865mm F5.75
R=5x150s, G=5x120s, B=5x110s @0C, autoguided with SXD2 mount
Stacked in DSS without any dark, flat and bias calibrated
Processed in PI

Tried different channels taken with different exposure of each sub to see what result would come out.
