The summer has proven challenging weather-wise here in the UK. The original plan was for 5 hours each of SII, Ha and OIII on this object. I got pretty close to completion last night before the clouds rolled in. I have decided to call it therefore, even though I am still 4 subs short of target. This is my Esprit 120, with QSI 690 atop a Mesu 200 in my home observatory. Data captured between 27 May and 19 August 2017 and consists of: Ha: 18x1200" OIII: 13x1200" SII: 13x1200" For a total of 14.7 hours Data was then brutalised using PI and PS.
