Deep Sky Imaging Session - May 2, 2025

The sky after midnight is clear so I setup my ZWO ASI294MC PRO with Borg 76ED Refractor to try to image NGC 6188 Rim Nebula or famously known as the Fighting Dragon of Ara in the constellation of Puppis. This subject is challenging because it is very low in the southern horizon and almost touching our roofdeck between 20-26 degrees altitude only! I use SVBony SV220 Duo Band Filter, a 7nm narrowband filter to capture this beauty. I was only able to get 120 minutes total integration time before it gets obstructed :(
