Image Description and Details :

I aimed to recreate the Iconic Hubble Space Telescope image Pillars of Creation. It was my first project I did at such a long focal length (Celestron C11 EdgeHD - 2800mm) and the struggle was real... :) I took my telescope to a semi-dark site for a weekend for the first tests. I knew it would take me about three nights to take this image, calculating a night's worth of shots per color (using filters for Hydrogen, Sulfur and Oxygen). I threw away the images from the entire first night (5 minute shots) as the guiding was not able to keep the stars small enough. I spent three more nights taking 1-minute subs for the final image, many of which also had to be discarded unfortunately. I ended up using a total of 175 minutes of Hydrogen, 192 minutes of Sulfur and 104 minutes of Oxygen. Celestron C11 EdgeHD Rainbow Astro RST-135, RST-300 ZWO ASI 1600MM 06-07.2022

Image Description and Details :

This is a Narrowband image of the iconic M16, NGC 6611, using the Sulphur, Hydrogen, Oxygen (SHO) Hubble Palette convention.
Central to the image are the “Pillars of Creation” as detailed in the famous Hubble Space Telescope image.
The result was very different to my previous work with M20 and I have to say, much easier to get an aesthetically pleasing result.I firstly removed the magenta hue. The blue and gold colours were there from the outset but I enhanced these whilst subduing the green. Overall the result is, I think, in keeping with other reference images that use the Hubble palette.
I used Starnet and then Photoshop, using Kevin Morefield's process to end up with a high quality starless image. From there I was able to apply a number of processes such as HDRMT, LHE, and Unsharp Masking, with judicious use of denoising as well as Curves Transformation to improve the sharpness, definition and contrast, evolving the colours to the classic Hubble palette appearance.
I initially added back the SHO stars, dealing with the usual pink halos, but subsequently reprocessed my RGB data to add back the RGB stars. This gave a more natural and colourful appearance to the stars, which integrated very well. I subdued the stars with Morphological Transformation coming to what I think is a nice balance.
