Update: I got sub arc second guiding with Easytrack and Autoguide when i was out a few days ago: (Graph uploaded on Astrobin) https://astrob.in/full/mlbcpm/0/ Even though it is possible to calibrate

Thank you Gary, happy to help! Great tip, this also means you will visually get a rough idea/understanding of the guide calibration, so when PHD2 moves the scope east, back west, north back to south

I will add one note to this info - and thanks Gabriel - MUCH more than I was asking for but very much appreciated. That note is that using a standard refractor as a guide scope (i.e. a guide scope) if

Thank you Gary, much appreciated! /Gabriel

Gabriel, HATS OFF TO YOU SIR! Super exercise ... and definitive results. Great job. Gary Myers StellarCAT

Just for fun this evening i tried using Easytrack on it's own without any DSC just to see if autoguiding is able to compensate for such basic tracking. I have marks on my scope so i manually can point

Hi Raphael, Your welcome Thank you and clear skies! /Gabriel

Hi Gabriel, Thank you so much to have described in detail how to autoguide ! It will be very usefull if I decided to autoguide in future ! Thanks Rapha?l

Here comes a description of the hardware and settings i have used to successfully Autoguide with my ServoCat driven Starstructure: *1. Hardware:* - I use a 50mm /180mm focal length Guidescope (Omegon

Raphael, Yes indeed! Since there was only the one GUIDE switch position on Gen1/2 hand pads I had to come up with a system that would support the dual buttons. It is as the labels suggest, though one

Dear both, Thanks to your message, I realise I made a confusion : I though the guide 1 was used for guide fast value and guide 2 for guide slow value. But this is completely wrong as you explained and

Indeed! The tracking can be extremely good. I had nights where I could measure it using a 240mm guide scope and a camera... and know what it was ... and in AZ it stayed UNDER 1 arcsec for a long

Raphael, Good question. First the main intention of GUIDE speeds is for visual use. At the eyepiece. It is there to allow you - looking into an eyepiece, to move around a field at a comfortable rate.

I am not using my scope for visual anymore, but if you leave the guide 1 values as they are and the switch on the ServoCAT is flipped to "1" visually you will not be using the guide 2 values when

Dear all, Thanks Gary to have explained the way the guiding correction works. You say " The way ST4 applies guiding is to add a fixed amount (programmed in GUIDE 2 speed value.... ". OK Then in his

At last guiding works as intended and without changing the settings wildly or going against PHD2 recommendations. From the last time out I have tightened the screws on my guidescope which caused it to

Hello Gary, Thank you for the info, interesting and helpful! I have read some about guiding on Cloudy nights and it seems other systems do the same, they add to the current track rate, so when they

Gabriel, Just a note on how the ST4 guide port works as implemented in the ServoCAT. First off both the AZ and the ALT tracking rates are changing continuously on an ALT/AZ mount. They will go from

Thanks Gabriel, clear !!!

I have seen very few images taken with dobs that have been autoguided, i can only remember one and that was on an EQ platform from Tom O, so i have only read about 2 that have succeded in doing this
