Here in Arizona the temperatures get so hot that it can degrade synthetic materials. Things like plastics, nylon gears, rubber gaskets, electronic capacitors, etc...
When the temps hit 100, it's only a matter of a few days before it's 108 - 115 degrees. During July and August, now sometimes in September, the temps go as high as 112-118 . That's material destroying temps.
This is the signal to pack up my 12" Meade LX -90 SCT. I've had it for 19 years and I really don't want to spend $3k replacing the mount. So to protect the mounts electronics and materials I pack it up and store it inside. There it sits in air conditioned comfort until around Late September or early October.
This is when I switch to using a stripped down bare bones 8" SCT with a Nexus Pro PUSH TO DSC system.
Between the sky mucking up from the heat and galaxy season coming to an end, it's a good time to pack it up. Besides, as globular and open clusters start to fill the sky, the wider FOV of the smaller scope is better suited.
Truth be told I do actually enjoy using this scope. I find it fun and easy to use.
