Location: Spain, Andalucia, Huercal de Almeria

Data Acquisition Method: Personal Telescope Setup

Description and Details: This is by far the most challenging image I've taken.

It's a 2x4 mosaic (8 tiles) taken on days with challenging weather conditions. Due to its faintness, I had to use BIN2X2 to obtain a sufficient signal; there are 50 exposures in Ha and 50 exposures in OIII per tile. I used dithering during capture and drizzle x2 during processing. Combining and matching them all was a minor ordeal for me. Using Spectrophotometric Flux Calibration + Multiscale Gradient Correction was essential to match the backgrounds of the 8 tiles once they were joined. Even after obtaining the master mosaic in Ha and OIII, the problems didn't end. Handling such a high resolution pushed my computer and my patience to the limit. The rest was the usual HOO process, and the stars were colored using RGB to NB.
