essex sky Posted March 2, 2010 Share Posted March 2, 2010 at last it was a clear last night.observed mars with my c8 at 200 and 250x.started around 2100 when the seeing was rather poor, could have been the scope cooling as it had been a mild daybut by 2200 at had improved markedly.the npc is still the most prominent feature but now shrinking. as at this time the quietface was turned towards me. but using a yellow filter, subtle dark shadings were still visible in the southern hemisphere in the mare sirenum area.also noted on the western limb 'the left edge of the planet as seen through the scope' there appeared to be a covering of bright white mist or cloud this was well seen with a light blue filter appearing almost as bright as the npc.here's hoping for more of the same soon:)clear skieslance Link to comment Share on other sites More sharing options...
Bizibilder Posted March 2, 2010 Share Posted March 2, 2010 I was looking at Mars last night from Norfolk - I had the same problem with very poor seeing - no detail on the disc and I could only just make out the NPC. Link to comment Share on other sites More sharing options...
essex sky Posted March 2, 2010 Author Share Posted March 2, 2010 hi bizibilderyes the seeing was poor here in essex early in the eveningat that time only the npc was visible and i was having to re,focus the scope every few minutes usually a sign that the scope has not cooled to ambient temp. later on things did improve a lot.which enabled more subtle detail to show throughsirius was very steady and not twinkling through binocularsa sure sign of good seeing.

DarkerSky Posted March 2, 2010 Share Posted March 2, 2010 Good stuff Lance. You're right about the NPC. It really is just a slither now compared to how it was a couple of months ago. I was out roughly the same time as you last night with Mars. There were 2 very bright features I noted other than the NPC. One was up in the Chyrse region - almost a band like brightness that extended off the eastern limb immediately to the north of Aurorae Sinus. There was a distinct lighter area on the western edge of Mare Acidalium too, just south of the NPC collar. I've been out again tonight and this brightness has gone now, so must have been cloud or mist or some other transient feature I never fail to get excited when I see Martian clouds. Funny really. Don't get half as excited about Earth clouds Link to comment Share on other sites More sharing options...
