Hi all,

I want to create a cloud/rain detection system with a MLX90614 infraredsensor. When pointed at a clear sky the temperature read is far below zero celsius. As soon as clouds move in the temperature rises considerable.
I want to create with arduino a utility that sensors a rise in temperature, indicating clouds, and shutting down the observing session. Parking the scope and closing the roof of my ROR.

Has anybody tried this or sees any difficulties?

Regards,

Joshua

so pointing roughly to NCP is required. You can't do it pointing straight east?

Hi,

Is it necessary to point the telescope in the direction of Polaris to execute the polar alignment procedure in Ekos or can it be done with every position?

I want to take 100 180 sec subs from for instance M33 but i want to re-align every 20 subs (1 hour).

I tried sequences: 5 jobs of 20 subs and align before each job. But the sequence makes a directory M33 for the subs and it will be used for the first job.
The second, third etc job can not make use of this directory.
So sequences doesn't work.

How can i do this?

Today during daylight i could get a good look at the focusser and there were indeed some allen screw a bit loose.
I saw while the focusser motor was running that the tube sometimes was not moving as if it was slipping.

Now the allen screw are tightend all seems to be ok.

The proof of the pudding i will see tonight.

I have tried other algoritmes but with no effect.
My focusser goes from 0 (full inward) to 100000 (full outward).
When i go to 50000 thru Ekos where my infocus normally was and i try autofocus then i eventually end up around 10000.
Then when i look at my focusser then i see the focusser at around 40000!!! So i thing it must be something like slippage.
I wil look at it today and hopefully i can image tonight.

Since a few days i can get into focus anymore whatever i try.
As i look at the v-curve diagram it looks like there is slippage in the focusser.
Anybodey have another clue?

See the screenprint:
