Hi,

 

I have an ASIAir Pro with EAF and external sensor.

In the EAF tab, you can set the AutoFocus sequence to be triggered every 1, 2, 5 degree variance during an Autorun.

 

Problem, I have checked my Autorun logs, and temperature variance has never triggered an AF sequence, only the time trigger (1 hr).

Log below.

So I decided to bag the sensor in a glass, and add ice-cubes see if during an autorun, AF would trigger. As EAF temp does not appear in the log, I have edited with what I captured on the screenshot of the EAF tab...

Nada....

 

Have you checked your Autorun logs, see if the AF sequence has been triggered by temperature? or only time?

Anybody else noticed this?

So nobody with temperature triggered AF sequence issues?
All working good?

I use the time setting instead of temperature, but will try the temperature if or when the sky ever gets clear again.

Thanks, some feedback mention the 2deg setting could be working.
But I am interested in 1 deg setting, as the FRA400 is a petzval, so focus and temperature.....

The wind and clouds just started to clear and I’ll give it a try for both temperate and time and will let you know too. Going to do that on my C11” Edge HD
 

Sebriviere, I have a FRA400 also and would be interested in knowing results on that from you using that as well. I’m still waiting for my second EAF to arrive so that I can install on the FRA400 and test that too.

You will love it. I use mine with ASI533MC-P, EAF and 462MC guider on OAG.
Just need clearsky to make best of it with ASIAir Pro...

I have redone my experiment being gentle on the ice cubes, and it works.
I got two instance of AF sequence strating for each settings 1 deg and 2 deg.

Note: be aware the temperature variation has to be in full integer, decimals are not accounted for.

Temperature started about 18deg. 1st ice cube.
Started Autorun with 180s lights...
About couple of minutes later, I did have the screen showing the AF sequence, and logged:
2020/10/28 23:19:10 [AutoFocus|Begin]: Run AF when temperature changed X degrees, 17.51¡æ changed to 14.52¡æ, exposure 5s Bin1, temperature 14.53¡æ
2020/10/28 23:19:10: Find Focus Star
2020/10/28 23:19:18: Find Focus Star: detect and calculate star HFD 0.0 , EAF position 1700
2020/10/28 23:19:18: Find Focus Star: not found Focus Star
2020/10/28 23:19:18 [AutoFocus|End]: Auto focus failed
This was first try at 2 deg, it did indeed required 2 full degree integer variation (17.51 down to 14.52) so decimals are ignored.
Second Autorun using 1 deg, reduced lights to 10sec.
Temperature was down 14.2 deg, about stable so added 2nd ice cube.
AF sequence showed up on screen and logged:
2020/10/28 23:26:09 [AutoFocus|Begin]: Run AF when temperature changed X degrees, 13.06¡æ changed to 11.96¡æ, exposure 5s Bin1, temperature 11.96¡æ
2020/10/28 23:26:09: Find Focus Star
2020/10/28 23:26:17: Find Focus Star: detect and calculate star HFD 0.0 , EAF position 1700
2020/10/28 23:26:17: Find Focus Star: not found Focus Star
2020/10/28 23:26:17 [AutoFocus|End]: Auto focus failed
Once again, decimal ignored and full degree integer had to differ (13.6 down to 11.96)

During some checks on my guiding cam focus, I ran an AF sequence on my main imager (ASI533MC-P) AF EAF value 1265.
about 25 mins later, redone an AF sequence before Autorun on NGC7000 AF EAF 1237.

Close to 30 steps within 30 mins.
And AF temperature trigger requires 2 full degree integer variation...

So, if you own a Petzval, make sure you select 1 deg and 30 mins, most of all if temperature change sharply in your area.
