Mars looks a bit like Venus...Like  a waxing moon..Like  3/4 sphere,  Am I just high or is this true?

Not just high, also correct - its got a gibbous phase. it'll be 'full' closer to opposition.

Although Mars is an outer planet relative to Earth, its orbit is close enough so when the Earth approaches Mars, we can see a bit of the shadow side. As we get closer, we'll become more face-on to Mars lighted side. So yeah, it does look like a waxing moon.

 

Opposition to Mars occurs on Oct 13. That's when the Earth will be directly lined up with Mars - we're seeing Mars fully face-on to the lighted side. That's also as close as we'll get to Mars, so with a good enough telescope, you can see some planetary details.

Of all the planets, Mars benefits most from the judicious use of color filters. Surface details pop more when you insert a red, orange, or magenta filter. The polar caps are enhanced by light blue filter.

Hi Mark. I just received my Mars filter and I have written down some colors to try as well for detail. I'll check back in after new moon. Since I'm a photographer (not astro), I have a ton of filters, just have to convert the sizes to 1.25 and 2". Best,
