Yes, something is not right! I use SIRIL to process my imagies and NINA to capture them. My first astrophotos a few months ago didn't have so many noise! They had just a bit of walking noise but hard to see... I switched to NINA from APT but the next time I will try to work with it. Also how can I do unguided dither in APT?

Thank you,clear skies!

Ok,thank you I use SIRIL anyway...

Thank you everyone for responding! Well,my ISO was 1600.

Also, how can I do astrophotography without darks? I hope subtacting the offset will work better.

Thank you again!

So, I have to use more data

Dither

Use dark frames

Rallemikken,Elp thank you!

I used bias frames with that image!

Ratlet thank you responding again. Ok, the goto accuracy isn't as much important as the tracking accuracy,I agree with that. I may start working on a project like this one Home Made Telescope Mount - Concrete Cellar. If I improve the worm gears( I want to make better that them) and use guiding I could have all of the trcking accurcy needed. And no, I am not working on an old mount I am making a new one from skratch! 

Ok thank you!

Ok that was easy! I have an EQ GoTo mount(the staradventurer Gti). Maybye a good amount of slew speed would be 2 or 3 right?

Thank you again clear skies!

Sorry about my teribble image!

Hello everyone! Three days ago, I captured the lagoon and trifild nebula with my unmodified camera;Canon EOS 60d. I took 125 imagies 60sec each. Then I stacked them in DSS and I processed the image a bit but I was dissapointed. My image was full of noise! I think that this is walking noise(I don't use guiding yet,so I cannot dither). I also didn't add dark frames. I should also mention that walking noise is getting worse and worse through the year. In the colder nights I didn't have any issues with it but now in the really hot I have! How can I overcome this problem?

Ok,Vroobel! My idea is quite simple; To make a DIY EQ mount(not harmonic). I want to use this mount for;

1.Astrometry 

2.Astrophotograpy

So,you see that I need much accuracy,in order to find faint celestial object. The goto accuracy is really important but I will have to use plate solving. I also need the Onstep controller to support guiding. This is a really good example of what I want 

I of course will use worm gears. And acording to you I souldn't use 400 steps? But this will do the tracking worse right?

Thank you again Vroobel!

Ok, Also a really impotant question; How can I improve the goto accuracy?

Thank you again, clear skies!

Ok,so I am going to buy this!

Thank you Vroober for responding again! I want to control my mount from NINA. I a this suggestion; To use the D1-r32 kit with the CNCv3 sheild. Could this do a good job?

Ok thank you everyone! So, what stepper motors sould I buy(remember I want a payload capacity of at least 25kg)

Also I will have a complex system for astrophotography that needs to be really acurate! What Onstep microcontroller sould I buy. I really need a good one!

Thank you everyone again!

What do you mean?

Hellon again,thank you responding! How can I face this problem?

Vroobel,I have to tell you something! You are the reason that I begun this project! I just learned so many from your videos and I think that I found the best person to advise me! Thank you providing me all the information needed. I am also designing a rotator because of you! Also what can I do to improve the tracking the tracking accuracy?

Thank you and clear skies!

Thank you AstroKeith! Do the Nemas 17 have backlash issues?

And also because you mentiond that you are motorizing a dob what else sould I buy exept the controller and the steppers?

Thank you,clear skies!

Hello stargazers! I would like to make an EQ mount with OnstepX. The microcontroller that I'll be using is the CNCv3.

I also want a NEMA 23 stepper motort(400steps) but others suggested me to buy the Nema 17. 

I want the payload capacity to be at least 20-25kg,so can you tell me what motors to use?

Last but not least what else do I need?

Clear skies,Manos
