IC1396 Elephants trunk from Norway

[Pryce]

Althoguh I can clearly see there's something wrong with the stars(I have enlisted the help of the big brains in the help section) I wanted to share this, since it's still only my third astrophoto to date.
Since I noticed the halo effect on the stars, I only did a quick and dirty edit, but star halos aside, it didn't turn out too bad.

But about the halos.  I focused with a bahtinov mask,  rechecked focus twice throught the night and stars seems to be nice and round(and in focus as shown below) across all the individual subs. So my first thoyught was a stacking issue.  I've tried stacking only the ligth frames but still got the same effect.

Hei Pryce. Bra med flere nordmenn

As your third astrophoto this is looking very well executed.

Guiding looks like it's a 10/10 with no noticable streking of the stars.

Setup loks great with the corner stars as round as the center stars, so that's good.

I'll let someone else comment abuot the stars. My guess is focus is slightly off, however could it be a dew issue? 

I see in your sig that you have a dew heater and strips, where have you mounted them, and where they on for this capture?

Nice image. Love the elephant nebula. What camera are you using? I use the optolong filter too and it really enhances the red channel which is maybe why your image looks as it does (I am careful to tune this down if it looks a bit over saturated with the red colour). 
The stars as mentioned earlier could be due to a bit of dew forming on your lens despite your dew heating strap (maybe make a cardboard dew shield as well?).

Astrophotography is a great hobby. I am loving my journey here so far and hope you do too.

I appliedsome photoshop magic that made the star issue less apparent

They are mounted at the base of the dew shield closest to the lens,  and they were on.  At about 50-60%.

I don't think it was dew, because the guys over in getting started helped me select a few different stacking parameters to test out, and with a few of them I didnt encounter the same haloing effect. But I did get some weird gradient in one of the corners that ruined the image in a whole other way 😂😂

I used a full sprectrum EOS 600D for this 😁

 

I absolutely love it so far! I don't even mind sitting outside in negative 15-20c while setting things up. And I hate the cold.  And the outside 😂

Every time I solve a problem or when what I'm imaging pops up on the screen for the first time I jump up and down like a giddy schoolgirl! 😆 

This is the coolest hobby I have ever started and I hope I NEVER stop!

Was the setting that produced halos the (3x drizzle) or similar in deep sky stacker? I remember that setting reeking havoc on my stars when I tried that a few years back.

I'm out imaging right now, but off the top of my head I cant say i know exactly what that is.  Can you elaborate?
