Iam still working on it...i have dec curve making high peaks and the issue of doubled stars come back again.... iam not ignoring u at all i attached a pictureas evidence i followed ur advice ....what should i do further to prove that....anyway thank you

Of course i will post full detailed post about my progress in this autoguiding problem...that is in my plan from.the start....i was following suggestion here until i was shocked by your last reply....any way thank you

Most frustrating ?!!! Anyway ...if u refer to your last comment about the photos i posted here...you pointed to the usb cable and said it was st4 cable while it was the usb cable ....i alrealdy replied to u and confirmed that i had disconnectrd the st4 cable while the cable in the photo u attached is the usb not the st4 ....if you read my topic and replies well, u would get my point that the problem in guiding was in the st4 and also the usb cable ...the guiding didnt start untill i connect both...that was what my problem was....I find also your comment about my posts in phd forum or here very weird ...is there a problem if i try to find solution for my obstacles in different places ?????

Hi Astroandy....thanks alot for the link....it was really helpful....Last night i begin my imaging session for IC 4606 and RHO OPHICHUI region.. i made around 40 ×3 minutes exposure slots....i used canon 200 D with optolong l pro filter and Redcat 51 scope....i am using skywatcher eq 35 mount... I am doing strectching now for the stacked photo....But the colors still not appeared now for the nebulas .

Thank you....i found star alignment in pixinsight and it helps me 😊

I dont know what i did wrong to get this angry reply.... I notrd from start of this thread that i am totally beginner....things that you may consider very simple and logic maybe so difficult for me to get it .... i shared with u all information i could have....i even attach pictures for my implementation to your ( Steve - David - Budgie) advices and if you refer to your last respond it was about my picture and aligning RA axis to the leg of tripod....so i wander why you said that i dont share anything with you..... i Put my screenshot for stacking of image because i was so happy that i finally get a nice image with good guiding because of your advice... so i want it to share with you and let you know what i am through now....Any way you were a great help and support to me....i really appreciate all your advice and follow up with me ....Thank you Malc- c

Hello , Iam still newbie for imaging sky....I have done imaging session yesterday for IC 4606 and RHO OPHICHUI region.. i made around 40 ×3 minutes exposure slots....i used canon 200 D with optolong l pro filter and Redcat 51 scope....i am using skywatcher eq 35 mount... I am doing strectching now for the stacked photo....But the colors still not appeared now for the nebulas .

I have done good session yesterday for IC 4606 and RHO OPHICHUI region.. i made around 40 ×3 minutes exposure slots....i am doing strectching now for the stacked photo....But the colors still not appeared now for the nebulas .

Thanks for the video i followed the steps and here is the shape of tripod now ...its still away alittle but better than the first look.... I dont understand the Marking of Home position...could u explain it more ?

This is excellent explaining for PHD graph ...thanks alot.... i ll try to follow video suggestrd by Budgie and advice from Malc c to make the RA axis aligned with the leg of tripod facing north.

Yes it was in the home position and i didnt figure out why the RA is away from the leg of tripod...but it become so after polar alignment adjustment by sharpcap

Thanks alot for all ur advices...you are a great help and support.... I am trying now to align axis by spirit level but it seems the RA is alityle bit away from the center...maybe the degree circle is not accurate

Thank you so much ... but i am still beginner and dont understand the meaning of X: 400 setting 😅 ?!

Iam doing now imaging session and i took some photos to record what i was doing . I started by making polar al9gnment with sharpcap i got excellent result but i want to say here that the final step in sharpcap alignment is to rotate the RA axis by 90 degrees then make the adjustment untill u get the excellent PA ...after that i returned the RA axis to 0 angle but it gives me Fair PA result so should i depend on the 90 degrees result or the 0 degree result ? I made new profile in PHD and new cal9bration i got perpendicular axis so i slew to my target which is IC 4606 and start guiding there.... i got the best RA and DEC curves through the last 4 weeks ....i know it may not be good bit its better than any curves i got before....i changet MINMO and Aggression values but i found the default setting is the best for my curves..... i start imaging the exposure was for 3 minutes i got very nice round stars.

Thanks David....i use sharpcap for polar alignment and got excellent result...i dont know why it gives me that large error in PA with PHD. I adjust the usb cable for guide camera as u suggested.

Thank you and i am sorry i thought i answered all questions....i connect the Camera to pc by usb cable and the mount to pc by usb cable ....i use eqmod to move the mount ....i create a profile in phd according to phd best practice.... tonight i ll delete all profiles and use shorter cable and start again

I disconnect the st4 cable.... whats shown in the pic u attached is the usb cable and yes u are right ...i should rotate the camera to release the tension in the cable.... I d like to know how to correct the periodic error in my mount ? ANd how to get perpendicular axis on the guide log .

Yes i have 5 M usb cable from mount to my pc.... I have a question here ...is the Pulse guiding the same as guiding rate in mount ?

Thanks for your advice...i was thinking in the aggression values...i ll try it tonight and come back to u

How could i solve the backlash or the periodic error ? Forgive me if i asked silly questions as i am still beginner and i have no one here either astro friend or astroshop in my country to give me advice about these issues 😊

But i use only one and i could balance it by getting to counterweight to the top of the bar.

Yes i wws doing it near polaris and i discovered it was wrong but i still have problem with guiding ....the RA curve has zigzag rough curve as in this picture

Sure here are the photos....by the way i just remove the center plate that support the three legs because i want to transfer the mouny when i took the photos....also i dont use the st4 cable during my last imaging ...i disconnect it from the mount.

This is my guidelog : https://openphdguiding.org/logs/dl/PHD2_logs_fFq6.zip

I balance my mount and scope always .... i use bubble level to balance the RA aziz at 90 angle then return it to home position at 0 angle. Also the same for DEC axis . I was thinking in the RA and DEC aggression values at my PHD profile
