Trying work with long time exposure in two sessions, in two differents days.

The image here is merely illustrative. You should see in large scale.

Nice image Jorge!

Are you using a coma corrector?
Just noticed in the lage scale image coma in the upper left corner of the frame. Could also be flexure, my setup suffers a bit from this.

Cheers,

Justin.

Thank you for attention, Atalas, Justin and Marc.

No Justin, I am not using coma corrector, nor any filter and nor guiding. Not yet ! :(

I am not sure if I will buy another better camera and filter wheel. So I am waiting for thi$ deci$ion ! :prey:

Because this I am trying more total exposure time.
Critical is repeat the same angle position of the camera every day.
Now, I will try any nebula. Two or four days, to get some hours of data.
