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!
