M8 Lagoon Nebula Startools OSC Narrowband
Had a great imaging session last night on the South Coast and captured about 4 hours of quality data on M8 Lagoon Nebula ( probably for the final time this year ) Moon was waning at 70%
Same set up and gear
NexDome Obs
8 f5 GSO newt
EQ6-R pro mount
ZWOASI2600MC set in Ascom Lowest Read Noise, Gain 100 , cooled to -10C
Optolong L Extreme OSC NB filter
78 x 3 minute dithered guided subs
Tracking and Goto EQMOD and Ascom Stellarium
Framed focused and captured with APT
PHD2 Multistar guiding at 0.70 arc sec error total
Subs reviewed in Astap
Stacked in DSS
Processed in Startools V1.7 Compose ( set for OSC Narrowband Bi colour )
Selected a few SHO presets in the Colour Matrix with only minor tweaks in saturation and colour bias ( mainly reducing the green bias )
Created Star masks and coloured the Stars independently from the main image
The 2600MC amazes me every time I use it , at Gain 100 Lowest read noise , you still get the benefit of good dynamic range but not at full well. The final image was so clean and low in noise , I only had to apply a 2 pixel noise reduction
Very pleased with the final OSC images
5 x OSC Narrowband bi colour SHO versions
1 x OSC Narrowband Synthetic Luminance version
2 x OSC Synthetic Luminance Crop versions to show close in detail
Comments welcome
Thanks
