NGC 6946 Totale 9 ore di esposizione con filtro H-alfa circa due mesi per avere giornate con un seeing almeno discreto. - Fatta dal centro di Torino. Lo scatto è solo un bianco e nero i colori li ho aggiunti in base a un certo criterio.

I do not want to undermine the job done, because to handle 9 hours of exposure and above all the patience to complete them in 2 months is admirable ... but I see a bit 'defects in this photo :-(
The stars are a little too big, but could be caused by seeing; But above all I do not understand what happened to the lower left-hand storage: that star movement is strange ... maybe it's all because of the alignment of the unsuitable frames.

Hello, nice the NGC 6946. In my view, colors apart, you should have the diameter of the stars .. you did not specify what program you used for pp, unfortunately even the monochromatic stars that give the photo the lack of depth Of the field. Now I do not understand if it depends on the end result or all the frames are so. Hi, Beppe

Thanks for the comments.

Unfortunately, turning a picture born in black and white is not easy. To this is added the seeing that distorts the stars and in the end as observed by you a bad alignment of the images.
About this last observation I have to have something pasted with Photoshop. By the power of watching all the stars the eyes go to the ball.
I tried to identify the level involved.
This is the result.
