Internal Guider not calibrating

Don't use backlash, I made that for a home made mount hardware, I will disable it. The calibration process takes care of that.
Select the ASI120 in the menu to use its ST4 port.
And try again using the default settings. That should work, I use the same setup
Anyway your last log file was almost empty.

Oh no, it is empty, indeed - and no other file stored from last night. What a shame.

Anyway, thanks for the feedback, and good to know better not to touch the backlash - do you think that could have been disturbing the calibration?

Quick question: is the calibration process affected the brightness of the stars, should the autostretch function be enabled?

Subframing shouldn't be used, binning 2x2 or higher, exposure time 1-2 seconds.

Why should subframing be avoided?

Now you can try my way of guiding. I am also having the same mount and ASI120MC for guiding.
1. under profile editor, guiding set to internal
2. Under Guide tab, choose via EQmod moun and bin to 2x2
3. under guide option page, follow my setting in attached photo if you wish to perform dithering.
4. Please remove ST4 cable!!!!!!!

Are you using USB to connect to the mount? I am doing that as well.

Good luck!

Great, thanks a lot! I never thought about not using the ST4 cable. I have connected the mount via Bluetooth to the Raspberry, as well as the ASI via USB to the Pi.

Best, Helge

try to connect the mount using USB cable and see any miracle happen? Pulse guiding either doing great with USB or RS232.

Hm..does it mean that the BT connection is not good enough to support guiding?

I still think that cable still play a very important role in transmitting data without failing.

My personal experience was that BT is even more unreliable than Wifi connections but it could also be just delusion

It's true. There is a noticeable delay with BT over USB with serial TTL adapter.

Hi all i noticed exactly the same thing over the weekend. Bluetooth works great inside my house with just the mount connected. Once i attached bluetooth moonlite focuser it starts to play up. Add guiding to the mix and forget about it, it falls over within a minute. It seems like there is just way too much data being transfered and bluetooth is just not up to the task. After changing to eqmod USB cabled connection the thing ran all night, no issues with pulse guiding (no ST4 cable) with a ASI 120MC and 2x2 binning and SER algorithm (looks to me that it is better than the smart algorithm, i don't know why, just an observation after using both).

One thing i did notice was internal guider worked flawlessly on my first target. After aligning on my second target and clicking on guide, the internal guider did not guide properly. I had to restart the computer to get the guider to recalibrate for successful guiding.

Is there is a way to just reset the internal guider calibration and have it recalibrate on a new star without having to restart everything?
