How do you control movement of the stars?

I mean... if i took a photo of 60 secs shutter speed... position of moon in the beginning is not the same at finish.

How do you get rid of "blurring" images?

Thanks... and great moon shots!!!

For astrophotography you need to use a motorized equatorial mount EQ, which follows the movement of the celestial sphere.

Ouch!

That's expensive... it's out of my budget... :(

But thanks for the answer ;)

I have  two hardware modifications for the camera too.

First I remove the internal infrared filter of the camera and replace with a external IR cut filter.
Later  I remove the optical from the camera (Leaving the electric connection pluged) and put an optical adapter.

With this I can do primary focus images.

Last night's lunar eclipse was taken using the camera A590 and Intervalometer script.

Very nice !

Would it take very long to adjust each frame so that the image does not jump around at all ?

Would require a lot of time to adjust to all 38 frames of gif.
The difference is about 2 pixels, and it would be delicate work, and the result would not be much different than this.

align_image_stack doesn't help?
