Mars polar cap looked smaller last night!!
the polar cap looked smaller last night compared with my first obsevation
made a few days ago , as Mars rotates can you see more or less of it depending on how much is pointing towards us? thanks Simon |

Thanks. I thought I was seeing things, but the cap even appears smaller over a few days in the fuzzy pictures I'm producing at the moment. It's summer on Mars in the Southern hemisphere and it's at perihelion, so it's probably getting quite warm for the place. -- "Forty millions of miles it was from us, more than forty millions of miles of void" |

it was pretty good in cambridge, but i stacked a x2 and x3 barlow lens and
the magnification was much better, but the saved images appeared darker, im not sure if it was the stacked barlows that did it or something else, Simon "Jim" wrote in message ...

Mars polar cap looked smaller last night - Its gone
I observed and sketched last night and again today. The polar cap appears to
have gone tonight. Syrtis Major is still visible although contrast is much reduced compared to last night ( and rotated a bit as expected). Mike A wrote in message ...

I'll post an image when I have the data processed. This evening didn't look too promising at first - as I went out the door it was raining and overcast. But I trusted the weatherman (!) and sure enough it cleared up. ChrisH UK Astro Ads: http://www.UKAstroAds.co.uk |

yes in Cambridge there was a little cloud but cleared as the evening went
on, the polar cap was less visable for me last night but still there, and Syrtis Major appeared a little smaller, i will have to see what happens when i get roung to do the image processing.
