Mars through the 13.1"

I viewed Mars at 3 a.m. this morning with my 13.1" Discovery Dob and noted Solis Lacus and Mare Sirenum, the only surface features that really stood out (besides the SPC). Solis Lacus had the "eye" quality to it when viewed through a #25 red filter. I used a variety of filters to decrease the brightness of the planet, the red filter finally working well with Mars so bright. I collimated the Dob just prior to viewing. Best views were with a 5.1mm Epic ED-2(293x), it's slightly darker images helped it compared to a 4mm Radian (374x). The ED-2 had some coma toward the field stop. I tried a 12.5mm Highlight Plossl (119x), but the image was just too darn small for my poor eyes. A beautiful night for viewing Mars and the deep sky.
