Getting ready for Mars opposition/close approach

Post by geyes30 »

In anticipation of the close approach of Mars in a few weeks' time, I took the opportunity to image the planet this morning. Unfortunately, it was super cloudy, and so I had little time to focus properly between the channels. Furthermore, thin whispy clouds continually obscured the planet during imaging, further degrading the image. Nevertheless, it was nice to be able to catch it from my balcony. Looking forward to more opportunities in the coming month.

Not bad a catch! What's your gear in use here?

The angular size of Mars was 19.1" yesterday, and will grow to 22.6" around Oct-13. That is a ~10% increase in size.

We are not going to see Mars this close until 2035 (then 2050)!
