Beautiful detail when Viewed On Black
I took seven shots at slightly different focal points of the inside of the trumpet of a daffodil, and used CombineZP ( a free software tool) to stack all seven images to create the final image.
Once the stack was complete, I selected the centre filaments and on a separate layer sharpened them with a high pass filter at 60% opacity, and then in a new layer, inverted the selected area and ran NR on it, before a soft NR over the flattened image.
Finally, after adding the drop shadow border, I ran two passes of USM after reducing the image size for the web.
C&C as always.

Petite balade dans un parc à Hyères (Var, France). La pluie ne nous a pas empêché de pouvoir admirer la diversité de fleurs, dont cette fleur à la couleur rouge bien pétant et ses pétales en formes de "pics".
The rain didn't stop us to admire the flowers diversity in a garden in hyères (South of France). Thsi flower was very peculiar as its color was a vivid red and its petals like peaks.

Centaurus A is the 5th brightest galaxy in the sky, situated about 12 million light years away. It has a peculiar shape and the theory behind this unusual appearance is that it was once an elliptical galaxy that collided with a smaller spiral galaxy.
I have imaged this a couple of times before but was inspired by the incredible image from Rolf Olsen (who lives in my home city of Auckland) to try and capture the red filaments revealed in his 130 hours deep field image from 2013 (with extra added in 2018). In Rolf’s image he revealed filaments A and B. However, in 2017, scientists discovered filament C running perpendicular to filaments A and B.
The very bright area at the center of the galaxy known as an “active galactic nucleus” is produced as a result of the galaxies central supermassive black hole accelerating particles away from the poles of the spinning accretion disk at high velocities and producing jets shooting out from the black hole.
From what I understand, the jet shooting out on one side of the galaxy (referred to as the northern jet), is photoionizing the hydrogen in the interstellar medium. It has also been noted that there are young stars in the inner and outer filaments (filaments A and B) and this could be an example of jet-induced star formation. The ionization coming from these stars appears to be insufficient to explain the high levels of ionization in the clouds that make up the filaments and so it is thought that the ionization producing the bright filaments may be from a combination of ionization from these young stars and ultraviolet photons originating from the jets of the AGN (active galactic nucleus).
Filament C, on the other hand, runs perpendicular to the other two filaments and it has been suggested that this filament could be the result of ionization from the galactic wind.
So the challenge for me was to show all three filaments A, B and C in my image which I feel I have successfully achieved with my 40hrs of Ha.
Because of the limited R,G,B data collected using the Skywatcher Esprit 120, I combined it with my data collected with my Meade 10inch SCT and ASI1600mmPro from back in April this year to improve the detail of the galaxy and it’s dust lane in this final image.
