There is still time, but not a lot. Since Mars is particularly large this time, it will stay larger for longer. It will be larger than 20 arcsecs until after the first week in September I have tried for new photos recently, but the results haven't been worth posting. It isn't just the Martain dust storm that is causing problems. The local atmosphere is particularly dusty at the moment, and the low altitude makes for a lot of murk to see through. Judging by the red dust on my car, it looks like bits of the Sahara desert!

To be honest it will be much better in 2020. It will be half way up in a dark autumn sky. It will be only a tiny bit smaller than it is now.

The change in the weather can't be helping too much either!

It isn't, but that's the way it goes - sometimes. The metors will be a wash-out this weekend, and Mars will have to wait until the end of the week at the earliest. :cry:

Missing the Perseids is a big disappointment. Saw one though the other night. Hopefully I'll have my new telescope before Mars gets too small!

This is Mars as seen on 14th August at 2221 UT. The image was dancing around like a bonfire was lit underneath it! The resulting stack of 120 from 1200 was not very good. However, it did show what appeared to be 2 southern polar caps! In fact the one to the left is the bright Hellas Basin. The dark areas are Mare Cimmarium and Mare Tyrrhenum. There are signs of faint cloud on the extreme left hand side

Mars is being left behind now, and is getting smaller. It also no longer looks 'full' and have a gibbous phase of 92% The features are clearer now that the sand storm has disappeared. The dark triangluar feature on the right is the Syrtis Major. The bright feature under it is the Hellas Basin, again looking like a second polar cap.

Nice detail. Shame it wasn't that clear when in opposition!
