Re: [ap-gto] 600E Temp Operating Range

I used my AP 600E GTO mount today to shoot an ISS transit of the Sun...



www.astropix.com/HTML/SHOW_DIG/055.HTM



I had planned on doing a daytime polar alignment, and then using the

GoTo to find Venus and focus.



But when I arrived at the remote observing site and plugged in the

drive and electronics for the mount, the hand controller wouldn't

work. The mount tracked, but no hand controller. I unplugged and then

plugged in all the cables again, but no luck.



The ambient temperature at the site was 92F, but it didn't work as

soon as it came out of the air-conditioned jeep.



When I plugged it in when I got back home, in the garage, it worked.



Is 92F outside of the operating range for the hand controller?



Any other ideas?



Thanks,



Jerry

Are you sure it wasn't working? It can be virtually impossible to see

the display in daylight. You have to shield the display thoroughly and

really work at seeing it. I suspect that it was working just fine. Try

it again in the bright daylight. To check it out, put it at the bottom

of a moderately deep small box and use your head to block the light

from the opening. You should be able to see the display as your eyes

adjust to the 'darkness'.

Hi Rick,



That might be what it was, I will have to try it again today in the sunshine.



I did try to shade it from the sun and cup my hands around it but

still couldn't see it.



I did notice that it beeped when I tried to press the west button.



It is very disappointing if this is the reason. Roland is so worried

about it working at minus 50 degrees, but it's not usable for solar

work in the daytime? That is almost inconceiveable.

Hi Jerry,



I don't know about the 600E but I have used my AP900GTO at

temperatures of over 100F and almost 90% humidity without any problem! 8)

Hi Chris,



And you didn't have any problem reading the display in the sunshine?

If it beeped, it was almost certainly working. I did almost the exact

same thing the first time I tried it outside in the daylight. The only

difference was that I was in my backyard and I had another keypad

available to me. I went and got it and when it didn't 'work' either, I

went back inside and powered up the mount in the basement with the

first keypad where I could see the screen just fine. I went back

outside and after much difficulty managed to get the screen into just

enough shade that I could finally see that it was working.

I really don't know what to say. That is just the way the keypad

screen is, too bright at night even on the low setting and far too dim

in the daylight. For my tastes, there should be four settings with an

ultra- dim setting about half as bright as the current dim is, and an

ultra-bright setting at least twice as bright as the regular power-up

setting is. Some nights when I am fully dark adapted, the display

actually seems so bright that it 'hurts' to look at it. I have cut a

piece of red Rubylith to put over the display but seem to lose it

regularly.

Well that's another matter. I had to hide under the hood to be able

to see the display. 8) When I do solar imaging I normally hide in a

hood. I used to be brave before and spent 4 hours solar imaging. I

got heat stroke and almost fainted. I was sick (fever) for almost a week.

Hi Rick,



I just took it outside from the garage, and you were right, it was

working, just impossible to see.



Thanks,

I wonder if something like a small piece of the Rubylith red cellophane laptop

screen cover, we use to preserve night vision, would work equally well on the

pad display in bright sunshine. If so, a snap on filter for the pad would be a

good option, for those doing daytime astronomy.
