I pulled the dustcap off the OTA the next afternoon, and there was still moisture on the corrector.  Gotta make sure to let things dry out when they get frosted over like that.

Absolutely stunning vista! The Sonoran Desert is one of my to see places. I have many cacti I keep here in KY, but the humidity and rainfall make it a challenge.

 

Best,
Randy

That scope has seen worse.  It spent the first 30 years of its life in Alaska, where you can only do astronomy when it's bitterly cold...

You've got the OTA mounted backwards, and could have goto/tracking issues... The fork arm should be on the left as you use the telescope.
Funny you recognized this. I did set it up as per text book instructions. But to me the focus knob was way too low to the base plus with the arm on the right works excellent. I guess because of my dyslexia and I am also left handed. With the focuser knob on the top is an easy to get to operation. When I did decide to put the knob on the top and the arm to the left. There was issues with the goto tracking. So I decided to switch the arm to the right to over come this issue.

It should be fork arm to the left, locking knob to the bottom.

yes and also avoid letting the handcontrol hang like it is now. a liitle use of velcro??

Where I grew up, there was still several hours of sunshine mid-winter.  However, between the 60* latitude, and mountains on the horizon, I don't think it's actually possible to do a marathon from up there.  Several objects simply are not visible.

 

Besides, most MMs are done in the spring, where there's no advantage to being up there for additional darkness.
