SH2-115 in Cygnus, imaged in SII Ha OIII and RGB. Done remotely from Spain with the 12in ASA Newtonian f3.6 and ASI2600MM pro. I collimated it 2 years ago after stripping it to wash the optics….Its such a stable scope even with the extreme heat of the Extremadura region of Spain.
Exposure times were 3 hrs in SII, 4hrs in Ha and 5hrs in OIII all 300s subs. Plus 1hr each in RGB all 120s subs. Processed in Pixinsight and Photoshop to finish it off. Thanks for looking Peter
