Description

87min integral RGB exposure of M11 and its surroundings, captured remotely using Telescope #5 (Officina Stellare Riccardi-Honders RH200 D = 200mm f/3, FLI Microline 16200) system of ChileScope observatory; over two observation sessions carried out on Aug 3 & 5, 2022.

The RGB image is photometrically calibrated using PixInsight tools and the further correction in Photoshop.

Taken in celebration of 35 years since my first observation of this wonderful object: it is the first Messier catalog object and deep sky object that I ever observed and identified
