Both emission Nebulae, the Flying Bat mainly composed mainly of Hydrogen emission and the Squid’s emission composed of double ionized oxygen. An extremely faint object The Squid Nebula was discovered in 2011 by French Astro-imager Nicolas OuttersCaptured recently in Narrowband (H-Alpha and OIII) and Broadband using a QHY600 60 Megapixel Full Frame Monochrome CMOS camera mounted on a Takahashi 130 FSQ, courtesy of QHYCCD.This setup is available immediately for people wanting to subscribe to Grand Mesa Observatory's system 1.
grandmesaobservatory.com/equipment-rentals.In this Bi Color version (HOO) the H-Alpha is mapped to the red channel and OIII is mapped to the green and blue channel. The raw data was preprocessed using Pixinsight, the stars were then removed using a tool in Photoshop called "StarXTerminator and the stars were later replaced with the more naturally colored stars from the RGB data.Taken bin 2x2 over 17 nights between September and October 2021 for a total acquisition time of 51 hours.Technical Details
