Apologies for the same target popping up again, but I'm keen to reveal this now completed
first tricolour narrowband image with the new 10" f4 CF Newtonian & Tak NJP mount
Taken under LP in Suburban Melbourne.

Ha 3nm 22x10min
S2 3nm 18x10min
RGB 20x60sec ea
O3 3nm 12 x 30min (old RC8 OTA data - darn clouds!)
The resolution/contrast of the new rig appears to yield pleasing results
Peter Ward's direct critique of my previous attempt at this rightly prompted me to reconsider my approach to imaging, and to step up to the next level of equipment. I was able to part with most of my former gear, the proceeds of which funded the purchase of these wonderful new toys.
I figure that when experienced and respected astrophotographers take the time to critique one's images, one can either take offence and run away - or take it on the chin, suck it up & learn from/act on the comments, (however direct they may appear at the time).
I chose the latter and am grateful for the push
Description: ESO/APOD - Two unlikely nebulae located side-by-side. The pinkish nebula on the far left, known as NGC 2014, is an ionized gas cloud comprised almost entirely of hydrogen. A cluster of stars are responsible for the characteristic glow accompanying the ionization. When the stellar winds pierced through the galaxy, hydrogen atoms were stripped of their electrons when they came in contact with ultraviolet radiation streaming from young, energetic stars . The clouds of gas were then reborn when the hydrogen and their electrons recombined.
Its blueish partner (pictured on the right) is NGC 2020. Its bubble-like cavity was naturally carved out as gaseous material was carried away by stellar winds.In contrast to NGC 2014, the bluish hue seen here is the work of one single, massive, unstable star called a Wolf-Rayet star. Instead of acting as an agent for the ionization of hydrogen, this star is responsible for ionizing surrounding oxygen atoms. (Hence the variation in color)
The rose-like Dragon Head Nebula NGC 2032/2040 is pictured to the right.
