Hello and thank you in advance for taking my upcoming submission into consideration.
The image I'm submitting is an integration of Planetary Nebula SH2-188.
The data was acquired in the following dates:
06.08.2024, 07.08.2024, 10.08.2024, 11.08.2024, 05.09.2024, 06.09.2024, 07.09.2024, 08.09.2024, 09.09.2024, 13.09.2024 [dd/mm/yyyy]
Location:
Dâmbovița, România
My name:
Radu Marinescu
Total integration time:
33h 10′
Description:
With its one-sided, semicircular, filamentary gas structure, SH2-188 is a weak and unusual planetary nebula in the Cassiopeia Constellation. It represents one of the most extreme examples of interstellar medium contact, or how planetary nebulas interact with space. It is a good candidate for examining ISM effects because of its large angular dimension (in comparison to many oother such nebulae) and apparent high proper motion. The central star of Sh2-188 is an evolved entity that has shed most of its material and is on the verge of transitioning into the white dwarf phase. Based on its age and structure, it is generally thought to be an old planetary nebula. It is located at a distance of around 850 light-years, close to Ruchbach Star and was photographed for the first time in 1965 by Gaze V.F. and Shain G.A.
Equipment:
SkyWatcher 10" 250PDS / 250mm 1200mm, Hypertuned EQ6R-Pro, ZWO ASI294MM Pro, ZWO EAF, ZWO EFW, ZWO LRGBHSO, ZWO OAG w/ ZWO ASI120MM-Mini
Processing details:
Pixinsight - WBPP, local normalization, DBE with GraXpert, SCNR, generalised hyperbolic stretch, local histogram equalization, wavelet transformation, HDR combination for the faint and bright regions of the Ha, narrowband combination, narrowband normalization, selective color correction, noise reduction with a blending between NXT, GraXpert Denoise and Topaz Denoise for an ultra clean result. Sharepening and detail enhancement was only performed by deconvolution with BXT and wavelets.
Stars were processed separately, SXT, SCNR, morphological transformation to fix saturated star cores typical for Newtonian, lightness reduction by iterative stretching and deconvolution, selective color saturation. Small final touches, crop and export from Photoshop.
