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

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.

Really nice close up Jorge. Lovely stars.

[jsmoraes (Jorge)]

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 !

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.
