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

Thanks Gabriel for clarification. You indicate your unguided precision is " 0.08 arc seconds per axis per second". In the last session I did to improve my ratio, I measured initially a 0.05 arc

I would also like to take the opportunity to correct myself. I have now read the PHD2 documentation (mostly the troubleshooting section) and according to what is written there, if you get large/abrupt

Hello Raphael Glad it is of interest! 2.0-2.5 arc seconds unguided for my sub exposure time which? is 10-13s with only a slice of time from 1 night as reference so would need more nights to verify

Thanls Gabriel, Really appreciate how you share your experience ! Try astrophotography using my 36" Fullum alt/az is a target for future and with your explainations it becomes clearer what to do. And

I appreciate your gratitude Mickey, luckily the hard work has also been very interesting and rewarding! /Gabriel

Thank you Gabriel for the hard work and time you put in in this project so far. I am hopeful to use this in some way with my rig, using SharpCap. We will see. Thank you Mickey

Thanks to the moon i have been able to dedicate the last 3 clear nights on getting autoguding to work with my ServoCat driven 30" F3.4 Starstructure dob. The first night i used a guidespeed of 25 arc

I downloaded your image as a *.png and then did some Pixinsight + BlurXTerminator + NoiseXTerminator + StarXTerminator + GHS.? Then did some predistortion in GIMP, then went back to Pixinsight and

Beautiful image Gabriel. Unless you wish to go thru the mind numbing exercise of full deconvolution in any post processing program and then not have it work the way you hoped (& that will be the case)

Here is my latest image: 1073x 10s (2h 59m) on NGC 2336. Distance about 100 million light years. Data from 2 nights (Thurs-Fri & Sat-Sun). High res: https://astrob.in/full/a12fsd/0/ I have thought a

To close out this thread… Sunday night we set up and then the dew and clouds came rolling in. We just kept everything covered, no observing, no testing. We probably won’t be out until the end of

Gary and Bill, I had a friend make a cable for me. It will be a while before I can test it. My scope is stuffed into our cargo trailer, next to Amelia’s. So for now, lets consider this case closed.

Steve - I'm sending you a private email. BC

Gary and Bill, I think I figured out my hand paddle control issue. When I plug the HC into the port on the SC I can get the motors to spin. Image .2325. If I trace the cable from the SC going to the
