Deep Sky Imaging Session - February 17, 2025

The sky this evening is clear after a hard rainfall this afternoon. I took this opportunity to image SH2-308 Dolphin Head Nebula in the constellation of Canis Major . I was able to image this nebula before also under the light polluted sky of Manila last March 2023 but my image processing skill was very novice. With some added knowledge in the coming years, I attempted again this faint nebula in the city of Manila once again using 3 hours total exposure using my trusty ZWO ASI294MC PRO Astro Camera on Borg 76ED Refractor with 1x Flattener and SVBony SV220 Duo Band Filter at -5 deg C. I know I need to give justice to this beautiful faint nebula by adding more integration time in the future. Nevertheless, I'm very happy with the output.
