| Scope, mount, camera: | 12.5" Newtonian, f/5.1, MAM50, ST-10XME |
| Filter, exposure time: | LchiRGB, Lchi = L+R+G+B, L = 20*180s, RGB=(17x17x12)*300s |

| Comments: | Image seeing: 1.9" Data reduction with THELI, colour composition in PS. The longer integration times in R and G compensate for not so good transparency in one of the nights. The image was resampled from the native scale of 0.855"/pixel to 0.700"/pixel, resulting in about 2.7 pixels in the FWHM. |
